The block prep work is a good idea, but a few tips. -Leave the decks alone until after the block has been bored or decked. Your detailing might end up being removed by the machining. -You should chase all your threads twice - once before going to the machine shop to verify they are all good, and once after all of your machine work and detail work is done as part of your final cleaning to remove machining swarf. Thread chaser work best, but an old dull tap will also work. -when cleaning out blind bolt holes, turn the block on its side so the hole is parallel to the ground and use brake cleaner with the plastic tube to blow the crap out. Use a cloth over it unless you want to wear it. You will get a lot more crap out of blind holes this way than just using air, and the brake clean is also a degreaser than doesn't leave any residue. -Run a flat file over the deck to knock off any burrs caused by your detailing. You are not trying to remove metal, so just a few swipes in each direction will do. -Using a rat tail file, carefully remove any raised area from the original staking of the front oil galley plugs to hold them in. Again you want to just remove the raised part. This will make tapping it much easier. -When chamfering the bolt holes on the decks, put the head gasket on first and see if the holes are blocked or are open. Some engines have unused bolt holes. You don't have the chamfer them. Also, don't chamfer the water passages larger than the gasket. You are removing sealing surface, and many head gaskets have smaller holes in the water jacket passages than the block because they are acting as a restrictor to force water to go to the back of the block. Don't open up these holes. You have to understand that the reason you chamfer the holes is because the bolts will pull up the metal adjacent to the threads creating a small raised area around the bolt holes. Most factory original blocks will have a small chamfer, but if the block has ever been decked, it will probably be gone. The chamfering adds a little bit or crack resistance also, since it is much harder for a crack to form on the chamfer than a sharp edge. There is no downside to doing it.
You can't mention worldwide V8 technology without mentioning Edelbrock. When Vic created his company way back in 1938 he had no clue that he was creating an American legacy. What he did for the automotive performance world is unequivocal. I can't tell you how awesome it is to know that his entire family kept Edelbrock progressing after Otis Vic Sr passed. What an amazing story of ingenuity and what you can do when you set your mind to something.
That’s what I was thinking. I’ve had a couple Chevy 350’s that made over 500+HP N/A. They could have used better parts and got more than 520+HP without having to use the $7K+ supercharger
Boosted power is different then big cam power. The set up they showed can be used as a daily driver, impervious to heat and atmosphere. The old school cam set ups, load up, they don't like the heat, the power sucks down in the low rpm's, they buck with a stick shift at low speeds, etc. So hate on this all you want but it's not a bad deal.
Travis, didn’t say anything about 1,000 hp daily here. Just sayin if I put the amount of money they put in it, 518 seems fairly low since a typical 350 with decent heads and cam can put you north of 450. This is hardly more bang for your buck.

As it turns out though I don't think, historically, Khan or Washington were prone to great fits of laughter, one being brutal and the other being very soft spoken. When i think of laughing lunacy I think Roman emperor Nero, or Caligula.
wow for the money all that cost and only 518hp what a joke,weve been building 500 plus hp 350's on the street for 30 plus years with no supercharger and not even close to this much money
And this right here is why I LOVE fuel injection! It just WORKS! And you don't mention it but it bears pointing out that this engine will run the exact same way in cool air, hot air, dry air, humid air, high altitude, sea level, and It DON'T need no steenkin jet changes or air bleed adjustment or accelerator pump cam swapping! Especially with today's ethanol gas. I REALLY like the idea of something I can park one day and still run perfectly the next
It most certainly doesn’t just work. This past year my shop installed 2 self tuning kits that had the whole computer stop working, one couldn’t get fixed for months because of parts shortages. The biggest problem with carbs is most people think they can tune good when they can’t, a properly tuned carb has no problem starting up the same every day.
@@stephenkrambeck6589 IF they are used right. Carbs are temperamental. When they work they are splendid. But if you let them sit, something evil this way cometh. Bottom line, if you are on top of it, they are fine. But don't think they are hands off devices. A good car guy checks things. On the other hand, not being able to get parts for a bad CPU is equally aggravating. Makes you really appreciate a Toyota Camry that just runs! Boring as they are, factory cars really are reliable these days.
@@stephenkrambeck6589 Agree. Only truly reliable efi system is on new oem cars GUys assume aftermarket will be the same, spend thousands of dollars and half the time put a carb back on.

This exact combination was offered by Edelbrock as a complete crate engine 4-5 years ago. They just used the same parts, assembled it, and ran it to match Edelbrock's claimed dyno numbers.
This video is prolly even older than that... the basis for Edelbrock's HP claims was prolly this blower on a stock 1975 SBC 350" with actual 7.6:1 compression ratio...
People are complaining about the peak hp without taking into consideration that the engine n/a with that cam and heads is making somewhere between 375-390hp if I had give an estimation with what I have seen before with even better AFR heads on a 350. So when you really think about it adding 130-140hp ish is not bad.
These guys commenting have NO idea what they are talking about. It's really hilarious to read. The 519 number is really good out of a 350ci engine on pump gas. No crazy parts. Will run for years and years and years. You can't daily old school engines making huge power. This one is made for burning tires and having any where you want to go. Blowers look cool, sound cool.
@Randal TheVandal first the hr motor isnt a stroker... its 350ci.... yes they did a 383 not what i was talking about... second i can do pistons cam and heads for a hell of a lot less than a blower... the point was why waste money to make a lot less power... and you can make well into the 400s on 9.5:1 with no blower that will beat the higher hp blown engine..
@BW MadDog [retired] i personally like a balance or hp/tq for a street car ive had a 383 with 450/480ish n/a its plenty on the street... brother has an 86 el camino ss... roller 350 sniper efi... e-force 122 charger w/pulley 8psi... e-street heads and cam... th350 w/3.73s... its fun... prntscr.com/sdjbiw ... wasnt the point just saying thats a bunch of money for little gain on their part
Ive been reading about how superchargers work and the reason why it doesnt make as much horsepower as you might think is because of the massive pulley wheel on the supercharger the motor is definitely more cappable than 500 horsepower
To everyone complaining about the low numbers, here's a few things to keep in mind. The setup is running on essentially the stock tune which is made very conservative for longevity purposes. If they did a bit of tuning and rejetting, you'd probably see another 25-35hp alone. Next is the stock 10psi pulley. A 12 or more psi pulley (with proper tuning) is obviously going to jump the numbers up quite a bit especially with bigger carbs. Lastly, head choice plays a really big factor in any forced induction application. I set of higher flowing heads would also increase hp/tq numbers without changing anything else.
Its fuel injected.. no re-jeting required. Depending on the injectors, may not need new injectors either. I believe this is a really solid motor. It can be a daily driver, get stuck in traffic, and run into 100k plus mileage wit no problems. Most of the comments are not taking into account real street use. This is a expensive set up though... nice, but very pricey.
@@hawkdsl Didn't catch the fuel injection part. Either way, you have a good point of this being tuned for longevity. Once you get into the 8 and 900+ hp range, it becomes harder to maintain the smooth "daily driver" aspect of a build like this.
@nallen100 yeah NASCAR engines are not good on the street dumb FUCK...They are designed for sustained high rpm driving...They have like 13:1 compression dumb ass....Not exactly practical in a street car...Wise up butter cup
@@bilbobaggins4710 LOL, cool off a little there sparky. Your "not with a 350ci" is a broad statement indicating that no matter what a 350 won't make that kind of power. These guys are simply taking every situation where you CAN make more power, application aside, and saying yes it will. @Justin Bozeman provides the method of determining an engines power and clearly shows that 800-900 hp can be achieved on a street car. End of the day, this was a VERY mild "blown" engine.
At 1:20 it says 1996 was the final year Chevy installed the small block, that was only for the corvette. The 1/2 ton trucks carried the small block until 1998 and the vans/1 tons I think a couple years later.
10.8:1 355 or ls vortec 240-260 @ 50 600-610. 112 lsa . 1.6 roller rockers under drive pulleys. Now you have saved enough money for a 3000-3500 stall, 4l80e and Ford 8.8 or 9".
It looks like this was an application-specific combination designed to have eye appeal, dead reliable pump gas power, and modern fuel injection for a nice street rod. Also to talk about Edelbrock. It wasn't a max effort racing engine. Could they change up some components and double the output? Absolutely. Perhaps people are missing the intended application of this engine build.
I'd like to see this engine at 15 lbs of boost, however, the limiting factor will be those hypereutectic pistons, so you'd want to make sure you have some methanol injection to cool the pistons further than a heat exchanger.
I think this build is more a tribute to Vic edelbrock. That engine is nearly 100% edelbrock. Just the basic dimensions are Chevy. Years ago, I think Hot Rod wanted to do a budget performance street engine. Their choice was the 350. So they went to the junkyard and bought a 350. Well, it was a 2 bolt main. Couldn’t find a 4 bolt main in the wild. Chunked the block and bought an aftermarket 4 bolt block. Had a cast crank. Chunked that and bought a steel crank. Ported the heads and cut it for larger valves. Aftermarket aluminum intake, lumpy crane cam (don’t recall about the connecting rods) and voila a really decent street engine for it’s day. But sounds like they couldn’t do what they set out to do. Not bad mouthing the 350 just the mentality of the builders.
500hp out of a 350 (5.7) liters isn't that hard. 400 hp on very mild cams and middle of the road heads is common already. A blower should see in the 600's easy.
Looking at some of the comments here I'm thinking some of you guys have uses optimistic dyno's in the past ? This unit on 10 psi giving 500 on the brake at fairly low rpm is what you'd expect. If the heads are any good it should make a bit more on a weaker AFR 12.9 - 13.5 is where the power is at, but at the risk of piston damage if everything is not as good as it could be
I’m pretty sure the guys at MotorTrend’s Engine Masters made 1300+ Crank horsepower with an unmodified stock 350 bottom end and a centrifugal supercharger
Definently not stock 350 bottom end, but yeah 518 hp out of all this? Nobody who has a fucking supercharged 350 running on race gas cares for smooth driveability. They need to retard their timing, gush more fuel into it, and up the boost at least 5 psi for some decent power. Even if the low end suffers a bit, nobody street races in the low rpms. You'll pull up to the drag strip, beat your competitor the first 75 feet then get left in the dust.
A ZZ4 block with production parts, and HYPER pistons, 9.5 pushing 10lbs boost on pump gas! Fuel injected $$ dead nuts street reliability, 2300 blower, and a superior roots type blower drive. Oh and it's inter cooled too. For what it is INTENDED TO DO......this could be a blast in a street highway cruiser. I would have no problem putting this in my street strip cruiser 88 s-10 blazer, 78 Malibu, or my 68 Impala, and drive for many miles. Every body thinks they can build 1000 hp in their driveway.
Exactly. The guys running their mouths are keyboard warriors that have no idea what they are doing. 500hp in a properly set up street car will smoke a Hellcat. They all think it's easy to make huge numbers today.
@@DamionG1987 Hey it's the sign of the times I guess...plastic fantastic store bought super cars. Big HP numbers in throw away plastic cars. Tear up your hell cat trying to be chief doughnut maker, no problem. Get mom or dad to co-sign for another, and go crazy. I am a big time car nut, my whole life. But some of these squirrels never heard the line.....DON'T LET THE SOUND OF YOUR OWN WHEELS DRIVE YOU CRAZY.
Factory 350 block is good to about 450 hp according to experts, so they can't really push this build but real nicely done though, builders and testers say one would have to go to dart block with thicker main material to do much more hp.
Perfect mill for it Almost every single commenter here is clueless about engines from thier posts. Even the ones that claim to build for 20 yrs Torque is king on the st look at that curve!! Low end tq is amazing
depends what your judging criteria is... it is certainly one of the most mass produced... but best? I dont think so. I would judge an engine on actual engineering and efficiency rather than production numbers
you can make 500+ with a 350 and no boost. and id be taking an LS apart anyways to gap the rings for boost so maybe a little cheaper. maybe but those blow up too and around here people figured that out so LS arent as cheap in the northwest anymore
4:23 “We will be using... pushrods” ahh yeah I thought that the small block Chevy was DOHC thank you for that clarification. Lol great video tho just poking fun at ya.
No not the best. SImply a daily driver capable engine that is reliable and makes stupid torque starting way low None of these commenters imaginary 500hp na engines will make this kind of torque...anywhere.
I think you should do a SBC build where you replicate the Z28 DZ motor, but then put a six pack Holley set up! You could take it a step further and make it a full roller set up to REALLY make the RPMs scream!
@@Bozemanjustin good to know! I'm most curious about how a six pack works with I high revving, small displacement motor? Will it unlock the best of both worlds?
@@jeffrey4547 my theory goes as such, small displacement dz setup would run on center 2 barrel around town, possibly fair fuel economy (for a carb V8) but then on the highway you lay into it and use all 6 barrels! Seems like the perfect scenario! They used to run these things will dual quads stock! So I know they can handle the CFMs
@@WC_Beer_Reviews my pro built 327 for drag racing built by bell automotive running over 1200 hp the blue prints required 2 485 carbs . any more i would lose power by putting to much fuel in it and i'm running a tunnel ram a bit different then fuel injection or just a six pack but runs pump gas the best .
Was hoping you guys would redeem yourselves after the nitrous Iroc disaster........ welp, a guy can hope 😂😂😂. Maybe use an LS next time, no way you guys can screw that up.
What tuning? The A/F is good, after that you have total timing (which should be retarded from N/A) You can move the cam around with a cloyes set. I dont see it.
@@BuzzLOLOL Sincerely, ... Not as reliable vs. belt/chains that can stretch over time or with really high torque engines. Not a humble brag, but money wasn't an issue, I wanted the noise, 600lbft torque, naturally aspirated 410 SBC, legit dead on timing for 23 years now.
That’s funny! I know of several people who have 530hp+ mopar small blocks without a blower and on a stock rotating assembly!! Check Simpson speed shop for his 68 dart for build specs. That’s so cute, it needs a four bolt main to handle that power 😂😅🤣🤣 a mopar small block can handle 600-800hp on a stock rotating assembly 😂 oh chevy 😂 must be nice to finally have a real small block that can keep up with a mopar from 50 years ago. (Referring to the LS of course)
Just fyi, you can achieve this and more hp for less than half the money with a 177 supercharger. At 10psi on e85 with no intercooler i was a little over 600hp with my old sbc. Technically this can be done NA but without as good a curve
So many people whining that it only makes 500 horsepower. People buy this because It looks cool. It's a street engine that looks right in a hot rod. There's plenty of ways to make more power, but it might not look as pretty. It's EFI too so you don't have to worry about adjusting two four-barrel carbs. To much rich for my blood. I'll stick with junk yard shopping!
Damn I do most of that work for free in my machine shop. If I use torque plates I chase and chamfer the threads for my own sake, and I’ll chamfer oil galley passages/thread oil plug galleys for anything over a mild build.
If you max out the motor to aprox . 500/500 what type of top end transmission would be suggested is it possible to get the car to 230-250 mph and what type of speed set up could be used of off the shelf ?
There is a lot of people talking about the output of this....it's a very mild small block to begin with and the blower is not a super efficient deal. Granted a bit more power could be tuned out of this. But it's a car show , old guy , parade engine.
Correction, Edelbrock was NOT the first person who built a small block with one horsepower per cubic inch. Chevrolet was the very first and surpassed 1hp/CI in 1957 with the fuel injection 283 with 290hp but advertised it using 1hp per cube.
@@kurtpoblenz2741 and since this video is about a small block Chevy and NOT a hemi, my comment still stands. Was only referring to the video saying that Edelbrock was the first to do so, which they weren't.

the stock footage of them attaching that screw to the buss bar is hilarious. you guys really got your moneys worth out of that clip lolol
Really only 518 hp out a blown sbc . i have made that with vortec headed sbc naturally aspirated. Come on guys.
Not with a 350ci. You didn't
@@bilbobaggins4710 yes they do you just dont know nothing about engine
@nallen100 yeah NASCAR engines are not good on the street dumb FUCK...They are designed for sustained high rpm driving...They have like 13:1 compression dumb ass....Not exactly practical in a street car...Wise up butter cup
@@bilbobaggins4710 LOL, cool off a little there sparky. Your "not with a 350ci" is a broad statement indicating that no matter what a 350 won't make that kind of power. These guys are simply taking every situation where you CAN make more power, application aside, and saying yes it will. @Justin Bozeman provides the method of determining an engines power and clearly shows that 800-900 hp can be achieved on a street car.
End of the day, this was a VERY mild "blown" engine.
@@Dakktyrel the original commentor admitted he was referring to a 400ci Dart block there "sparky"...
At 1:20 it says 1996 was the final year Chevy installed the small block, that was only for the corvette. The 1/2 ton trucks carried the small block until 1998 and the vans/1 tons I think a couple years later.
Joseph Julian as late as 2000 in Tahoes had 350's. Someone on this show evidently didn't do much research
10.8:1 355 or ls vortec 240-260 @ 50 600-610. 112 lsa . 1.6 roller rockers under drive pulleys. Now you have saved enough money for a 3000-3500 stall, 4l80e and Ford 8.8 or 9".
It looks like this was an application-specific combination designed to have eye appeal, dead reliable pump gas power, and modern fuel injection for a nice street rod. Also to talk about Edelbrock. It wasn't a max effort racing engine. Could they change up some components and double the output? Absolutely. Perhaps people are missing the intended application of this engine build.
Bingo. 500+ is a *lot* of power for most street rods.
@@dennisyoung4631 Most commenters have never expreienced a true 500hp 350.
Beyond clueless!!
I'd like to see this engine at 15 lbs of boost, however, the limiting factor will be those hypereutectic pistons, so you'd want to make sure you have some methanol injection to cool the pistons further than a heat exchanger.
Or do it right and use forged. WHen hypers break its like a bomb going off it will destroy every part of that engine even the carb.
That young amish guy sure knows his stuff when it comes to superchargers & Chevy V8s
How much does he like spinning that speed handle 😂
I think this build is more a tribute to Vic edelbrock. That engine is nearly 100% edelbrock. Just the basic dimensions are Chevy. Years ago, I think Hot Rod wanted to do a budget performance street engine. Their choice was the 350. So they went to the junkyard and bought a 350. Well, it was a 2 bolt main. Couldn’t find a 4 bolt main in the wild. Chunked the block and bought an aftermarket 4 bolt block. Had a cast crank. Chunked that and bought a steel crank. Ported the heads and cut it for larger valves. Aftermarket aluminum intake, lumpy crane cam (don’t recall about the connecting rods) and voila a really decent street engine for it’s day. But sounds like they couldn’t do what they set out to do. Not bad mouthing the 350 just the mentality of the builders.
518 hp out of blower sad 😪 should be 750-800hp
Not much power you get more out of a stock ford Barra 4.0 L straight 6
500hp out of a 350 (5.7) liters isn't that hard. 400 hp on very mild cams and middle of the road heads is common already. A blower should see in the 600's easy.
Jr's Garage I know lol then they said a forged crank is needed 😂
@@Bozemanjustin yeah but the blower is eating 100hp
It's a Chevy don't expect to much.
These dudes the masters of low hp builds
I Kind Of Miss Seeing Tool Box's And Tools, Named Snap On, And Mac Tools. Matco Sure Shines Nice.
Man, this would’ve been a badass build in 1996!!!
you mean 1976
1966 .....i corrected you
1956...
Lol
Wouldn’t mind seeing an LS and Coyote episode with roots style superchargers🤗
Looking at some of the comments here I'm thinking some of you guys have uses optimistic dyno's in the past ? This unit on 10 psi giving 500 on the brake at fairly low rpm is what you'd expect. If the heads are any good it should make a bit more on a weaker AFR 12.9 - 13.5 is where the power is at, but at the risk of piston damage if everything is not as good as it could be
Actually, the RPMS is HIGH... look at the chart... 6200 - 6500 RPMs... should be making that HP without the blower with 200cc heads and 234/238 cam...
makes my top half heme orange painted 7176 with avs carb look like a baby but will find out I be happy with 350 400 hp out my old 318
Dylan Leonard Sounds like a Mopar to me. Check out Nick’s garage and uncle Tony’s garage for a budget build
I'd be livid at those power numbers considering what "little black and blue" made with zero boost!
YOU BEST NOW POWER NATION
I’m pretty sure the guys at MotorTrend’s Engine Masters made 1300+ Crank horsepower with an unmodified stock 350 bottom end and a centrifugal supercharger
im pretty sure they didn't.
Definently not stock 350 bottom end, but yeah 518 hp out of all this? Nobody who has a fucking supercharged 350 running on race gas cares for smooth driveability. They need to retard their timing, gush more fuel into it, and up the boost at least 5 psi for some decent power. Even if the low end suffers a bit, nobody street races in the low rpms. You'll pull up to the drag strip, beat your competitor the first 75 feet then get left in the dust.
@@spicketspaghet7773 ever watch NHRA?
A ZZ4 block with production parts, and HYPER pistons, 9.5 pushing 10lbs boost on pump gas!
Fuel injected $$ dead nuts street reliability, 2300 blower, and a superior roots type blower drive. Oh and it's inter cooled too. For what it is INTENDED TO DO......this could be a blast in a street highway cruiser. I would have no problem putting this in my street strip cruiser 88 s-10 blazer, 78 Malibu, or my 68 Impala, and drive for many miles. Every body thinks they can build 1000 hp in their driveway.
Exactly. The guys running their mouths are keyboard warriors that have no idea what they are doing. 500hp in a properly set up street car will smoke a Hellcat. They all think it's easy to make huge numbers today.
@@DamionG1987 Hey it's the sign of the times I guess...plastic fantastic store bought super cars. Big HP numbers in throw away plastic cars. Tear up your hell cat trying to be chief doughnut maker, no problem. Get mom or dad to co-sign for another, and go crazy. I am a big time car nut, my whole life. But some of these squirrels never heard the line.....DON'T LET THE SOUND OF YOUR OWN WHEELS DRIVE YOU CRAZY.
Factory 350 block is good to about 450 hp according to experts, so they can't really push this build but real nicely done though, builders and testers say one would have to go to dart block with thicker main material to do much more hp.
Gm rates them low to be safe knowing they are capable of a ton more
dream engine for my truck
Perfect mill for it
Almost every single commenter here is clueless about engines from thier posts. Even the ones that claim to build for 20 yrs
Torque is king on the st look at that curve!! Low end tq is amazing
Just found this channel. A hidden gem👍nice editing.very talented guys👍
This is a TV show that was on Saturday mornings on spike TV when I was a teen, to a young man 30 years ago. Some of these videos are that old.
Best eninge that's ever been made.
depends what your judging criteria is... it is certainly one of the most mass produced... but best? I dont think so. I would judge an engine on actual engineering and efficiency rather than production numbers
Locktite is your friend on blower drive setups. Have had and seen many come loose
Great job lots of really good info for the diy shade tree car guys
Whew ... Did you see those piston ... Things ... 😆 Sweet ...
Dollar per hp, a turbo LS completely destroys these old boat anchors.
you can make 500+ with a 350 and no boost. and id be taking an LS apart anyways to gap the rings for boost so maybe a little cheaper. maybe but those blow up too and around here people figured that out so LS arent as cheap in the northwest anymore
4:23 “We will be using... pushrods” ahh yeah I thought that the small block Chevy was DOHC thank you for that clarification. Lol great video tho just poking fun at ya.
SBC had DOHC in 1990...
I LOVE IT!!!!! THANKS FOR SHARING!!!! YOU MADE MY NIGHT!!!!
I have a question? I was wondering if y'all could do a video showing how to tune for a timing and degree what very much love to learn that
They put out the same amount of horsepower as a 12:1 350.. good job, you won the interwebz
Those edelbrock heads are holding that thing back. Should be at 600hp with that boost..
Small block Chevy best overall motor you can get
Ridiculous only 500 horsepower out of a blower motor and it only cost them $20,000 to do it if that's the best elderbrock can do
Rob Mcclure
Hey but it looks cool lol
They Have to SELL shiny JUNK to the People that don't know any better...
No not the best.
SImply a daily driver capable engine that is reliable and makes stupid torque starting way low
None of these commenters imaginary 500hp na engines will make this kind of torque...anywhere.
@@Firstmajortomlikestoticker Ignorant statement to the nth degree.
Do you even own a car? Sure dont know anything about blown engines.
I think you should do a SBC build where you replicate the Z28 DZ motor, but then put a six pack Holley set up! You could take it a step further and make it a full roller set up to REALLY make the RPMs scream!
@@Bozemanjustin good to know! I'm most curious about how a six pack works with I high revving, small displacement motor? Will it unlock the best of both worlds?
i use to have a 327 that we built it like the 302 dz same stroke and i would run it against this engine any day with just a 4 barrel
@@jeffrey4547 my theory goes as such, small displacement dz setup would run on center 2 barrel around town, possibly fair fuel economy (for a carb V8) but then on the highway you lay into it and use all 6 barrels! Seems like the perfect scenario! They used to run these things will dual quads stock! So I know they can handle the CFMs
@@WC_Beer_Reviews my pro built 327 for drag racing built by bell automotive running over 1200 hp the blue prints required 2 485 carbs . any more i would lose power by putting to much fuel in it and i'm running a tunnel ram a bit different then fuel injection or just a six pack but runs pump gas the best .
500HP on a built blown 5.7L? eh. 20 years ago impressive. Not anymote. AFR heads can make 500HP on a 383.
That wasn't impressive 20 years ago, or 30, or 40.
well most of the shows this channel is uploading are from 20 years ago XD
And the LS especially with a turbo
The right build small block AFR headed naturally aspirated will top out at 750 hp.
Man give me that engine I'll take it no matter awesome job guys 👍
ive got a 355 sitting in the garage that makes 700+ and its a damn street engine... #chad speier heads ftw!!!!!
Was hoping you guys would redeem yourselves after the nitrous Iroc disaster........ welp, a guy can hope 😂😂😂. Maybe use an LS next time, no way you guys can screw that up.
Hope that FI system works better than the E-street trash I purchased
Man a cam and heads should get you past 500hp it's almost 6 liters!
I can't believe they put champion plugs in it
I love watching the builds and of course the numbers but I needa stay away from the comments.
Thank you for the tips!
I love how everyone says that it’s a pathetic power number but don’t understand that with a bit of tuning they can get 800 horse out of it
What tuning? The A/F is good, after that you have total timing (which should be retarded from N/A) You can move the cam around with a cloyes set. I dont see it.
@@sandyshoremann7524 Simple pulley swap will get you way more boost out of that blower.
Putting this in my c10 🥵
A 1" ball stone can be used to put 1/8" chamfer on top of each lifter hole to keep oil on the lifter
Still have yet to see a build by these guys, show(s) that uses a gear drive timing set.
Nobody uses those hokey gear drives...
@@BuzzLOLOL And why is that? Dead nuts timing is not appreciated on Gen 1 blocks anymore? 🙄
@@jasonrobertsutliff - Gear drives expensive, noisy, not as reliable, the noise upsets EFI computers...

“Lightweight cast iron block”
500 lbs. engine instead of earlier 1,000 lb. engines...
That’s funny! I know of several people who have 530hp+ mopar small blocks without a blower and on a stock rotating assembly!! Check Simpson speed shop for his 68 dart for build specs. That’s so cute, it needs a four bolt main to handle that power 😂😅🤣🤣 a mopar small block can handle 600-800hp on a stock rotating assembly 😂 oh chevy 😂 must be nice to finally have a real small block that can keep up with a mopar from 50 years ago. (Referring to the LS of course)
RIP Vic Edelbrock Jr.
Just fyi, you can achieve this and more hp for less than half the money with a 177 supercharger. At 10psi on e85 with no intercooler i was a little over 600hp with my old sbc.
Technically this can be done NA but without as good a curve
So many people whining that it only makes 500 horsepower. People buy this because It looks cool. It's a street engine that looks right in a hot rod. There's plenty of ways to make more power, but it might not look as pretty. It's EFI too so you don't have to worry about adjusting two four-barrel carbs.
To much rich for my blood. I'll stick with junk yard shopping!
I agree. Would like to have that set up to take to cruise ins. Junkyard shopping 👍. A man’s shopping mall.
Seems like that engine could use some more camshaft, 1.7.1. Rocker Arms and 12-15 PSI of boost.
Forged crank with a powder rod? I think I'd have opted for a forged piston and rod, and not worry about a cast crank at those power levels.
Cast iron cranks can be used at 500 hp.above that, shops say go steel crank
Powdered steel forged rods are great, they're stronger than the old stock forged rods smallblocks came with originally
$14891.95 for that E-FORCE ENFORCER CRATE ENGINE. Golly!
And yet they just did a SBF 347 stroker that made 550hp+ on 93 NA.
You stole my thoughts, I was hoping someone posted this and U did .
Damn I do most of that work for free in my machine shop. If I use torque plates I chase and chamfer the threads for my own sake, and I’ll chamfer oil galley passages/thread oil plug galleys for anything over a mild build.
Can you imagine all those upgrades just for 500 hp..
There using a small pulley. If you use a larger pulley you will make roughly 700hp
Question when adjusting for zero lash by turning the push rod are you feeling for slight drag or when the push rod can't spin anymore.
Drag........any drag. But it's the First noticeable drag, then you stop.
@@stevenon5664 thanks brother
Actually, jiggle it up and down until no clicking...
5:15 why are you putting anti-seize on the crank snout? The two parts are too close together for rust to build.
@BW MadDog [retired] Guys with no videos have all the answers.
If you max out the motor to aprox . 500/500 what type of top end transmission would be suggested is it possible to get the car to 230-250 mph and what type of speed set up could be used of off the shelf ?
Not enough power to go that fast in most cases
There is a lot of people talking about the output of this....it's a very mild small block to begin with and the blower is not a super efficient deal. Granted a bit more power could be tuned out of this. But it's a car show , old guy , parade engine.
Why you not using Summit electric water pump? You said last time it doesn’t eat up hp like a belt driven pump.
Great viewing
Beautiful move P N good luck
I didn't even look to see when this video was made and I was thinking it must of been a while ago cause Pat has hair😂😂
Gallery bro, Gallery. A galley is a kitchen on a ship...
The blades on that supercharger look like they suck something through it they had some gouges
Brad Binion
I noticed that also. I figured quality control was on break that day
*_IS ANYONE ON THIS PLANET IMPRESSED BY THIS HMMMM NO ONE OK!!!!_*
Correction, Edelbrock was NOT the first person who built a small block with one horsepower per cubic inch. Chevrolet was the very first and surpassed 1hp/CI in 1957 with the fuel injection 283 with 290hp but advertised it using 1hp per cube.
Terry Kehler ......actually Chrysler did it with the hemi before Chevrolet. Everybody always thinks it was Chevy , but it wasn't.
@@kurtpoblenz2741 and since this video is about a small block Chevy and NOT a hemi, my comment still stands. Was only referring to the video saying that Edelbrock was the first to do so, which they weren't.
All those blocks come out to about 15,000,000,000 pounds of metal! if each bare block weighs about 150 pounds
You know we’ve come so far when 300 ci was considered a small engine
