- FULL RESULTS. SBC HP HOW TO, TRIPLE TEST, MILD, MEDIUM & WILD. Using the same 350 short block, this video shows you how to build a mild combo for mileage, torque and towing, a dual-purpose, performance street/strip combo and wild, race motor. Three SBC combos, with completely different power outputs and power curves, depending on the components applied. Choose wisely!

Was nice to see a comprehensive test on an old school small block. They always respond well to sensible modifications!
Great Video Richard! Nice to see a section on more of a daily/ tow setup. Most people always want to see the high HP numbers, but some of us like to see the performance down low where it would be used in daily use.
Me too. Got trucks.
They are underrated. Most of us can have plenty of fun with a sub 6000 rpm build made with torque in mind. The old Isky 264 mega cam remains one of my favorites for general purpose fun. Given the tech of the day, how he got so good so fast at his craft still amazes me.
Awesome content & one of the only vids out there I’ve ever seen with dyno proven gains with each mod being done! I’d love to see more videos like this from you!!
This was a great test. I like the step by step upgrades and dyno for each step. You are the man Richard!!!!
Hey RH, your content has been my medicine during this lockdown pandemic! Thanks for the "NO" BS content and delivery. Keep up the great work!
Thanks, will do!
This Hits the spot... Like a double shot... Great info Richard like for real... And very helpful player💪🏾💪🏾💪🏾... Finna share this about 25 times right now I swear
Thank you, this helps me so much . Your generosity with your skills and knowledge is greatly appreciated.
By far the best TH-cam channel that gives you all the ins and outs of combinations of motors and listens to his comments and I just love it.
Absolutely
Love your videos so much great information! Keep it up man, appreciate all u do for the car enthusiast who watch informational videos thanks again
This is the way all dyno comparison videos should be filmed. Bravo!
Great video. For a practical street car which will spend little or no time at 5500 rpm or higher, the choices seem clear. Solid info.
This was the video I been waiting for! Well done sir👍👍
Richard definitely deserves more subscribers! He doesn’t fill his vids with off topic crap!
This is probably one of your best videos for your average Joe good job Richard
Just goes to show you how good an old school chevy small block was and personally I think how it still is. Really nice job with this video.
I built a 'mid' level sbc with a comp cam 280, .480.480 @ 110 lsa for 10 years in an 85 chevy short/wide. It's now with its 4th owner and in its 4th vehicle still running like a champ. Love me some SBC!
I love a guy that post real stuff and not ad for a company... cool cat. I am working on my 1955 hardtop i have put a vortec in so this has been some really valuable info for me. Thanks for your time.
This was awesome! I'm doing a 383 for my wife's 87 monte carlo ss. I'm probably shorting myself on heads, but I've got vortec heads with edelbrock dual plane air gap, 770 street avenger carb and comp xr276hr cam
That last portion of the test where you switched the intake makes me happy with what I did with my combo. A heavy truck needs that extra torque when launching into a mud pit.
I have a heavy truck my setup was close to the first build just bigger cam and better heads I think I might get close to 400hp
This was good for my old school small block soul.
Great Video. I have one in a wrangler and works well, but getting ready to play with it some. Thanks for the video.
I would love to see a similar video on a BBC. Thanks for your works man.
I rarely comment but this video is fantastic! Great practical information presented in a clear, understandable fashion. Information that is hard to find. Clearly a lot of effort went into this project. Thank you Richard!
Glad it was helpful!
People forget with all the turbo ls stuff and 1000 plus hp combos running the roads how fun 400 horsepower small blocks actually are .
Thank you bro. Love watching anything about sbc.
Honestly love this youtube channel.
That Qaudrajet will perform just as well as the Demon. Most people don't know how to tune a Qaudrajet. I've used the Qaudrajet for years. Some drag race series will even require the Qaudrajet. The Demon is a great carburetor also. I've had both and prefer the Qaudrajet just to be different. It would be nice to see a comparison of the 2 carbs by someone that knows how to tune the Qaudrajet. Cheers Richard Richard thanks for the great videos brother
I’ve got qjets on two of my cars. One has a 240 degree 560 lift at 050 cam and full cnc heads. It honestly wasn’t that hard to get the qjet running right on it just took some reading, Cliff ruggles qjet book helped out a lot. Holleys are fine I’ve had some before but the tuning parts are so expensive and they don’t feel as good driving as the qjet.
Love the video and thanks Richard for answering my cam/head question the other day
Even with all the LS stuff this is still one of my favorites. Big block stuff is still my favorite though!
Awesome videos. It still blows my mind how are we underrated these motors back in the day. And for those who did modify them people didn’t really say much but the moment someone said they had a 355 bored 10 over the first thing people screamed was “wow what a gas guzzler” lol 🤦♂️
They were never underrated
Absolutely love the videos n how thoroughly you test.
Great job, wakes up memories
this is another amazing test video! who dynos a tiny 2G 283 intake and carb? nobody but Rich, there are plenty of channels the test the usual stuff but rich test a super wide range of awesome stuff! thanks RICH!
Richard, thanks for these phenomenal videos. I am going to be adding a Nova SS350 to my garage to join my 512 stroker Barracuda. 👌 fastback
Sounds great!
Fabulous. My brother had an old, rusty, 1970 Monte Carlo with a 4bolt 350 2bbl. It said 245hp on the air cleaner - virtually the same as in the video. We put the engine in an old Chevy dually and added a 4bbl and manifold form a junk yard. No other mods - no headers, no cam, etc. We always wondered how much power we gained. It appears that we probably made another 25-30hp. It made that old truck come alive with a full load of oak. I enjoyed this video - the video didn't say but i assume it was working with a 4 bolt block
Thank you you give me hope for my 330hp gm crate motor. It's got the vortec heads but I thing some AFR heads, roller cam, RPM intake and 750 carb would bring it up to 500 HP.
I've always owned Ford trucks but when I built my speedboat, SBC was the only way to go. Awesome platform.
Thank you for these videos.great job
@Richard Holdener you could extend the content on your channel by meeting up with fans and showcasing their cars and engine builds and drive them and talk about results at the strip etc. awesome channel you are an engine master for sure. Thanks for all your awesome content. Very educational! Engine science😎
Great info. Motivates me to get my engine built.
SBC= The original LS! LOL lots of LS guys forget, they are still “small block Chevy”!
Uh. No we don't. All LS's are still small blocks. We know this. We aren't dumb.
whatre you doing here ;D
Sbc is the base but not an LS engine. Ls engine has all the new technology taken form the mistakes from the early days. Ls are more efficient but aftermarket has now helped the sbc make as mush power. You would never see Roller cams on early sbc and now aftermarket stepped up making the sbc more efficient. Yes ls is a sbc but it’s nothing like the 1 generation sbc. I would definitely build a sbc before doing a swap thanks to this video
FXIIBeaver you are a smart one! A Lot forget the Chevy part! Chevy been engine swapping Fords forever, lol
Kincent Carter love watching Richards vids! Very smart dude!
thanks for this! love it :D love all your videos
Richard , the king on content !
I'm building the Wild combo for my car, but after re-watching this, I'm most impressed by the ported 882's/RV cam combo. It's extremely basic and makes respectable power for many applications.
Now I wonder how, RV cam + Vortec heads + TPI would look (for a towing application)?
Loved the comparisons
Would absolutely love to see this same comparison but with a 400 ,/ 406 cid sbc, that would be very interesting!
Me too 🤞🏽
I’d like to see a mild to wild 400 combos video as well. I'm getting ready to build a 400 SBC to go in a 1968 Malibu station wagon.
Great video as usual. I built a solid roller 406 that made 611 hp at the crank and people thought I was full of BS. I had to show them how easily you made over 500 with a 350👍
That’s pretty big HP for 406 if it is truly a street engine with pump gas compression and a hydraulic cam. Unless of course your engine has high compression and a could cam which make it more of a race engine vs a street/strip engine.
Dan Myers Dan Myers I think he’s spot on, if you use the right combination. Think about it Richard got 542hp from the 350!
Cheers
I’ve got 660hp from my 434 sbc 10.8:1 comp
My 388 is at about 650. Not at all streetable (still street driven)but with the right parts, just about anything is possible
I have a 383 stroker 11.0 compression, 243/249 solid roller and afr 210s with a Holley sniper x flow system, I’d say it’s stout
Hi Richard, This mild combo sounds like the one in Chevy Rumble magazine May 2007? You have the best channel on TH-cam keep up all the hard work and the great content!
Baselining with the old heads made the following mods more impressive, but my first change would be vortec heads and a compatible manifold. No complaints with your progression, just moving to modern combustion chambers and ports is what makes sense to me. Looking back at the DZ engine, they kept some mid-range by using a dual plane manifold on a 7000 rpm engine. Looking at how airflow works, it seems to me the active cylinder only sees half the carb on a dual plane, thus could always use a BIGGER carb than a single plane, at least with the same cam/heads. Getting to 520-540 hp range with a 350 is serious stuff, especially the dual plane setup with little to no torque loss. Incredible stuff in this video, thanks Richard!
One more thing, we need to see TPI on the RV cam engine...
I mentioned the Vortec heads as an option in the video-they work well
Love your vids. Would love to see a vid testing cam timing on a stout n/a build!
I'm most impressed with the rv cam and ported 882s. That is almost as much power as any factory sbc with a lot less camshaft and compression.
Great job! Awesome info and well explained. Can you do the same thing with forced induction? 3 builds of mild to wild roots or centrifugal would be incredible.
Awesome video Richard. Now I think what you need to do is the ins-and-outs of the Chevy small block 400. It would make a great other guys episode I think. What do you think?
I'm also eager to see more "other guys" builds, especially BB & SB Mopars, and not just junkyard motorhome ones, lol.
Really interesting tests and some nice combos. Id sure like to see some detailed info on porting the 882s and like, that made a good increase
check out horsepower monsters. they did it made 380hp with 882. and the dart iron eagles still whooped their ass and they put about 1000+ dollars of labor into them not worth it. just buy dart vortecs
Ya i get it, its just sometime you got a good set of 882s or the like and not much money, iv got a few heads and shortblocks from oval track friends, usaly end up puttin turbo on them but its still fun to try to get the most out of whats there
You do great work bro
We need more videos like this
That was a great video especially with the 2bbl. I would have tried the 500cc 2bbl in this test.
Great video richard.
Awesome video Richard. Now I
Richard, I would like to see a test using a single plane intake on a mild SBC combo. I'm running multiport EFI on my SBC but dual plane EFI intakes aren't really out there for a 4150 style throttle body. I know my combo is severely mismatched now with the single plane RHS EFI manifold as it seemed to run a lot stronger back with a carb and a Performer RPM. Keep up the great work!
Nice shirt, I'm minutes away from Vacaville. .........I had those holley heads on my 355 but that motor is long gone, gave it to my lil brother, in favor for a LS.......
Excellent job like the old school gen 1 sbc stuff. I still have good cores left. It would be interesting something like this on BBC IV 396 or 402. Or like my next project a 540 BBC with only 9:00 CR that will hopefully run on 87 octane.
Nice builds
I add one more, Chevrolet what a design very good oil flow for oil pressure very easy to work on make horsepower and torque you can't go wrong
Wooooooooooo SBC!
would be really interested to see the real world difference between LS and small block chevy, both same carburetor, comparable intakes, as similar cubes as possible and same cam specs. would be kinda cool someday
Awesome video!
Good information! Good video! But what about was the last camshaft? One reason I like your videos is you help take out the guessing part of what the engine will do if I do this or that to it. And if I just is the same parts I will get close to the same power which is awesome for that I thank you. My first car I Hot Rodded was my 67 Galaxie 500 2 door fast back I put a 390GT camshaft a 428 Police Interceptor Intake with a 800 QJet carb. Car went from a top speed of 130 to a top speed of 150! From watching a lot of your videos I really messed up not putting headers on it stock exhaust manifolds are junk on 390 Ford
That 639 hp stock vortec motor was really pushing the limits. Anything past 450 with a stocker I start sweater.
Bloodviking
"what the heck, let's do all 3" 🤘😎🤘
That's Richard for ya!
Awesome! When do you sleep? Also can you do a full kill sbc? Like a 427 with tall deck Iron Eagle block , 18° Brodix heads, egg shaped cam and a 1050 dominator? thanks in advance!
Once again , thanks Richard for all you do in testing. My question is, I noticed this motor had a tci balancer on it. Are you seeing any gain in hp or just smoothness in the motor or even more valvetrain stability with this balancer. Elaborate a little if you can! Thanks. P.S. That dip at around 4,000 rpm is indicative of to wide a lobe separation. Tighten that sucker up to a 107 or a 106 and let er rip.
444 Ft lbs and 418 HP! That's a Street Killer and a towing machine! all around fun for only 350 inches, that's the way to go!
Great video sir.
It's already been mentioned, but I'll ad another vote for a similar video with a 454. Please
I’m actually looking at building my small block with specs very similar to the wild combo! Assuming ring gap was added, how would you feel about adding boost to that wild combo? Do you think the block could take it?
As I remember as a good combo was long tube headers with 3" collectors, ported and polished 202 high compression heads, Mantly 12.5:1 compression pistons with a Offenhouser 360 degree dual port high rise square bore aluminum intake manifold and a 780 dual feed double pumper carb and a Crane mechanical "phase 3 cam" with springs and screw in studs. Then a nitous shot of whatever your engine bottom end could handle. It made great power and it didnt break the bank. Drop that in a Chevy Vega or a Chevy Monza and go have some fun trying to get i tto hook up. No Idea what the HP or torque rating was but braggards were saying things like 800 hp and other just as unbelievable numbers but they were serious tire burners and I've seen at least one in the very low 11 sec range playing with the possibility of breaking into the 10's. I remember the anouncer at Cecil county drag strip anouncing him and saying "He's tickling 10's. Can he do it!" Which made me laugh. That's probably why I remember it so vividly. There was at least one guy in hotrod magazine that boasted a 69 camero with an NA small block running 9's I never saw it happen but I assume someone did otherwise it wouldn't have made it into the magizine. Back in the day those were some serious numbers. Perhaps not so much today with turbo charging and computers but back then that was big stuff.
That Offy intake is seriously obsolete nowadays. Probably wasn't much else available back then.
Since you had to answer it a few times, would you mind pinning the Wild Cam grind, in the comment section?
I was expecting XR288 myself. Glad the biggest of the SBC XE line is still so streetable.
Cool! I’m putting together a 355 with an eagle rotating assembly, and a comp 268xe! Not sure what heads to go with, because I’m trying to stay on a modest budget, but I also want a little more than a stock head
What heads did you use?
Love Seeing the old school sbc.. would love to see a run of the mill 383 with twin turbos oh and a carburetor.
Very informative, thanks
I love it, a stair step build from mild 882 heads to afr190's. You are really cooking now. I know ls stuff is tough and can make crazy power, I don't got any. I got a ton of gen 1 stuff that has no real value, but i have been lugging this stuff around, and I am going to use it up, making room for upgrades, maybe. My street strip car, mild or wild car dont care what generation of motor it has, just what it can do today. How do you determine what piston has enough valve clearance, up front, so I will be ready when I get to the big cams? Great job!
You should put a list of parts you used. I would like to build one of those engine combo.
Great video
Also remember that the vortec heads have press in head studs and screw in studs are needed for most aftermarket cams and can be installed by any machine shop also I would of liked to see the big afr heads with the rv cam that way we can see what can be had with a great set of heads and a small cam many people think that to much head is a bad thing but in my experience it’s nice to have a car that drives and idles great in all conditions even with ac on and have the heads carry the cam higher up higher in the rpm and have the cam do the work down low please do a test showing a small cam with awesome heads to show no loss down low and nothing but gains it not make as much peak but no losses thru the rpm range in a street car that is super smooth and see if the loss wouldn’t be much down low also what was the wild cam specs i don’t think you let us know and I think it’s a good idea to let everyone know that many times vortec heads are cracked at the junk yard be very careful preferably get them from summit or jegs
Would be nice to see & hear some of the dyno runs!
excellent rich!!!
Richard I was wondering if you ever took a set of 220 china heads and ported them to the point you had to put tubes between the intake valve's? I've hurd of this and was wondering what kinda gains you could get from doing this. Love the videos
This will help me with my 71 C20 custom camper
Great vid
Hey Richard! Finally putting my 60 over sbc together with 9-1 compression, afr 180 heads and a howards retro roller cam with 213/217 @ .050 and 485/495 lift on a 110 lsa. I hope it runs strong!
How did it turn out, I’m currently building a sbc 360 and was looking at the Afr 195,cam is where I’m stuck on
Thanks Richard!! For not burying the SBC for the favoring LS motors, and doing different engines also.. And those AFR 195 move some air 290cfm@.600 lift. I suppose you used the 65cc heads?
Richard Holdener thanks for shouting out my hometown 😂
Would love to see a wild 377 NA small block build!
I have put together a 383 stroked SBC and with the pre Vortec swirl port heads that I ported for low end torque. The engine was together with Keith Black flattops. I reused them and had everything remilled again. Now my compression is 10.2:1. Is that too high for a truck application???? It will be used as a truck and not just to haul me around town.
Another great vid mate,, Given that the first test was 2 barrel and a basic shitter, it really does go to prove that my thoughts that the specs quoted for the 89 L98 TPI Vette are ridiculously low. The full vid also adds weight to the advice i have been giving to others for 50 years,, That it is like baking a cake, the results depend on the recipe, putting 6 eggs instead of 2 doesnt meant it will be better, it all has to match up.. O yes that exhaust manifold has to be the worst flowing/port match I have ever seen, old Rams horns way batter. Eddie Australia C4
What we’re the specs on the bottom end? I know you said forged pistons. But was it a stock block, crank, and rods?
Would like to see a comparison of the lunati voodoo cams vs comp Xtreme energy cams
Forged pistons? What brand? With xtra valve relief? Final compression on the wild set up? Regular premium on the wild set up?
