- HOW CAN I MAKE MORE TORQUE FROM MY SBC? SHOULD I BUILD A 383 STROKER? HOW MUCH POWER DOES A 383 STROKER MAKE? WHAT IS THE BEST CAM FOR A STROKER 383 CHEVY? IS A 383 BETTER THAN A 350 CHEVY? DO I NEED A BIG CAM IN MY STROKER? WHAT HEADS SHOULD I USE ON MY 383 STROKER? IS A STROKER A GOOD CHOICE FOR TOWING? CHECK OUT THIS VIDEO WHERE I COMPARED A STOCK AND MODIFIED 350 BUILD TO A 383 BUILD TO ILLUSTRATE THE EXTRA TORQUE AND POWER OFFERED BY THE STROKER COMBO. THE GREATTHING IS YOU CAN ADD A LITTLE MORE CAM TO THE BIGGER MOTOR AND STILL HAVE ALL THE DRIVABILITY AND POWER OFFERED BY THE EXTRA CUBIC INCHES.

406 ... 030 over 400 always my favorite
The SBC 383 will always hold a place in history! Was the go to small block before the LS motors that succeeded it
My father, four decades ago, always said "Horsepower sells cars, but Torque wins races". Not a racer myself, but the cam in my 325 Dodge Hemi puts the peak torque right where I need it for passing on the highway in my '33 Coupe. Gotta love a Hemi.
More cubic inches = more torque & power = more fun 👍
AFR heads on anything really can make a combo come together they are just good, always
Yup. Pretty much my go to ford a SBF or a trick flow 11R
That "mild" 383" is a fantastic street engine. The numbers are bigger than I thought they would be.
be great in a truck, suv, van, or small rv
I build tons of small block chevys on my channel. There's no replacement for displacement!
I'm currently finishing up a twin turbo build and getting it ready for the dyno 👌
I had the same cam in my stock gen II LT1, but with AFR heads and 11.0:1 compression. It made about 460hp to the flywheel
Usually a 112 lobe sep. Works with 283, 110 a 327, 108 a 350, 106 with 400, depends alot on combo, such as valve size, rpm range, street or track, etc. But this is a better than most magazine or book cams with all ground on 110 lobe separation angle, also dial it in,dont trust gears !
Much rather have 406 vs 383 between those 2 choices
Love your videos.keep up the good work
More cubic inches = more torque & power = more fun . What's the part numbers on the cams for the 383?Thanks.
Built 350 Chevys for years until I decided on a 383 for my truck. Never looked back after feeling the difference between the two. 383 is a beast!! . Put one in a 260z Datsun body and ran ten flat through the 1/4😊 and it was mildly built with a set of aluminum heads. 💪😆
Wow! Love those 240 and 260s!! Too many love to post a 383 only makes a lil more tq will run about the same.
B F S! lol No comprison between my SR 350 and 383 not even in the same zip code.
Always build bigger
i have my dad's 66 Chevelle, that he got off his grandmother that she bought new. dad rebuilt the 283 in 1990 and again in 2001. i got in 2020 and drove it for over 2 years, then my dad and i built a 383 stroker. going from basically a stock 283 to a 383 was night and day. i can't stop the 0 to 80 pulls in it.. lol
Love to try that Mild 383 in my truck!!
Really appreciate your videos!
Good runners, would love to see how much the 383 would of picked up getting that 112 lsa cam out of there. I,d bet money with a few degrees shorter duration on both intake and exhaust and a 107 lsa camshaft that 383 would pick up 25-35 hp and torque accross the board.
Learned my lesson the hard way via an old mentor. Put a bigger arm in it not bigger cams.
Makes all the difference in the world.
Nice. I built a 381 (only 0.020" bored over) and made 511hp and 492tq. And that's with a 650 speed demon. The throttle response is awesome.
This way, if you like the power of a wild 350, but you don't want to lose out on the lower speed tq, build a wild 383! You get back the lower speed tq, plus a bit more higher speed hp. Great combo, especially with 4.11 gears for the street! Let's just say I have fun on the street and never even wound out the engine. Granny shift at 5k and she boots! One day I'll open her up
2hp/ci costs a lot of money lol. Most of my builds generate roughly 1.5-1.55hp/ci with conventional 23° afr heads, super Victor 2, and a solid roller
i have a 350.040, with flattops, stroker crank & a comp cam.. My heads are the weakest link but they have springs to match my cam
I had a 383 stroker in my 81 Z28.on the street with NOS..What a ride,,I missed that car,
A 79 with a 350 with a 268he Comp cam, headers, Corvette intake, 750 Holley DP. It would haul the mail!
Power from the tq cammed was more impressive than the others. WOuld be perfect for an Iroc or C4
This was a great video!
Would've been nice to also have seen a test with the 383 using the Vortec Heads & maybe a set of Double Humps,if for no other reason that most of us that would be building a 383 Stroker either already have one,the other or both types of heads already,or know at least one person....probably more?....with a set of them lying about 'doing nothing' they'd like to quit having to move around (or tripping over!) that they could get cheap?
Im a ford guy but 383 strokers are awesome motors
I built a 383 stroker engine with Dart Pro1 ported heads...keith black forged pistons...555 lift cam. High rise single open intake....850 double pumper Holley. 3500 stall TCI converter making 650 hp. & 650 torque at 5,500 rpm. Everything matched up & blue printed. It's a beast in my 1985 iroc z28 camaro!!😡🚘👍
650 hp and 650 lb-ft? 1.697 hp per inch and (even more so) 1.697 lb-ft per inch seems very high for a 555-lift 383
That combo would probably be around 500ish hp and 480 torque, no? 650 hp seems to be more like a well built 400cui combo.
And we all know torque and horsepower are not the same at 5500 rpm.
Bingo ,didn't want to bust anybodies bubble, but since you called it. Can't BS everbody. 1.6 hp. Per cube . Not with that combo. Sorry.
Where did your horsepower peak? I’m guessing north of 7k rpm?
So now you’re letting the cat out of the bag as to how I won all of these street races back in the 90s. Thanks a lot. 😂
A 400 CID has even more cubic inches! :)
That was very good information. I have a 350 and was wondering how to put more power to it and still keep it as a daily driver
Supercharger
@@2015_Rubicnnwhat supercharger?
the first 383 combo he showed would be perfect for that. BB torque down low, idle in traffic with the ac on
Great content
Would you mind supplying the full specs or part no of the cam for the mild 383? That curve is pretty much exactly what I'm aiming for, but I simply cannot find a cam matching the ones in the video, and I don't want to mess things up. Many thanks Richard.
Great video.
Richard how bout some examples of how a 112lsa cam could be lumpy yet a 109 could be pretty tame that will ruffle feathers!
Or explain the difference say between a sbc cam that uses 290 adv duration compared with an idential grind that uses 306?
Too many are regurgitating posts of "Has to be 106 for torque" type stuff thats not a blanket statement.
PRobably not wording it right but you catch my drift
Iv got a 383 tunnel ram dual 750 Holley brawlers. 10.7:1 pump gas , runs 10.7 in the quarter hitting 130 mph
Also use a closed cooling system with air chamber on top, this allow radiator to be filled to top with no external expansion tank like BMW, works better!
My question is the 383 is with 6 inch rods for wild and if you got a similar comparisom video with solid flat tapped
These videos are a wealth of knowledge!
How about a 5.7" vs 6" rod comparison, or maybe a 383 to 396 video? Keep them coming!
5.7 vs 6.0 rods showed no power change
I was also gonna ask his opinion on 383 vs 396 sbc
It doesn't cost any extra money for the 6.0 rods so might as well get them...
@@BuzzLOLOL on a 383 no. On a 350 yes because they crank is the same style but it needs to be a crank used for 6.0 rods
@@BuzzLOLOL you have to look close because some do specify even the cheap cranks. Scat has different part numbers that end in 5700 or 6000 for obvious reasons
Richard good job as always! What happens if you change bore from 4.00" to 4.165"?
4.165-bore smc? 4.125 is common for after market or 400 blocks
you can overheat with stock 400 blok, go as small over as you can
Hey Richard I enjoy all your videos and information! I was wondering if you had any dyno pulls with Lunati Voodoo flat tappet 268/274 in a sbc & the a Bootlegger HR in a sbc. I watched the short video of a 383 with a bootlegger but no specs of the cam.
I don't think those specific cams
Chevy guys really used to be stupid about this. The nitrous guys would use heads with giant valves (2.08/2.10" etc.) on a 383, robbing the crank from a 400 SBC. They should have been building 377 destroked 400s or perhaps a 406, for less bore shrouding (flow). A 383 is a torque motor and well suited to heavy cars/daily drivers/trucks on motor. Built a 388 (.060" over) for a 1960s P60 (cab forward 2-1/2 ton chassis) for a friend's ramp truck. Had so much low end with Promaxx 180cc runner heads and a RPM intake that he had to put a Brownie-box behind the 4spd trans and in front of the 2spd differential. The 327 was turning 3000rpm at 65mph, so I put a circle track cam in the 388 for a lot of torque (tight LSA) and it turned out to be a beast at even 2500, so hence the o/d unit.
Brownie box ??????
@@getthegaff1 Auxilary transmission behind the original, two speeds- 1:1 straight drive and one overdrive (aprox .7:1), and also a neutral.
Richard when are you gonna "Big Bang" the 350 on some turbos!!!!!!!
One day, I’d love to see someone build an engine to produce maximum power in an rpm range that people actually drive at. I’m old and slow, and rarely rev above 3000 rpm’s.
I think you are confusing the needs of "people" and your own needs. People watch this channel to find out what makes more power. The vast majority of enthusiasts don't run their performance motors below 3000 rpm when accelerating.
@@richardholdener1727 you are correct. My needs are not the same as people’s wants. Just as people describing their daily drivers as race cars. Most people need engines to do things like idle, and make vacuum. It’s cool to see an engine rev to 8000 rpm’s making 1000 hp, and if you have a dedicated track vehicle, great. 2 terms foreign to most people that would build an engine is duty cycle and overall power. Maybe I’ll make a video about those 2 terms that are absent from the automotive community in the next engine I’ll build.
I would like to see results of a 350 stroked with a 3 7/8 stroke.
Especially if you went one size up from the 3/4 race cam and used the legendary 7/8 race cam. Now that would be awesome 7/8 stroke with the 7/8 cam.....
What's the part numbers on the cams for the 383?
Thanks
Just saw the video and liked what I heard as this is exactly what I'm looking to build for street and strip. I have a Malibu wagon with a350 4bolt main block. Want to configure to 383 specs but don't exactly know what parts to use. Like to possibly get close to 550hp or maybe 600hp and use pump gas. I see you use AFR195 heads on your build, but what if you wanted to go higher with the AFR 220 Eliminator heads.Tranny choice would be to use the 350 that's in the wagon, change planetary gears include a trans brake and beef up the rear to 3.73 or 4,11. Since I'm new to the game, was wondering if you could compile a build sheet for the wagon. thanks in advance. Ray
you won't like a 600-hp 383 for street driving
So, I guess it's proper to choose reality. Definitly don't want to compromise fuel and drive with headaches. I'll go with the modified 383. Could you provide Cam manufacturer for 232/238-543/538 grind? Or Is there a lower engine assembly you recommend with the same cam, e.g., when choosing a package, should I go with 6" or 5.7" For I or H beam rods? Also with purchasing the AFR 195 Heads, would it suit best to include 1.5 or 1.6 rockers. Like I mentioned before I'm starting out and would appreciate all the advise I can get. Thanks in advance. @@richardholdener1727

How about keeping these 383's cool and what's the best way to go?
We need some Richard holder name brand parts is what we need would love to buy a cam that says Richard holder designed
SBC truck motor, from 400ci to 420ci or 434ci 😎
I could never understand why anyone would replace a 350 crank for another 350 crank. The cost to go to a 3.750 crank is minimal at best. I've NEVER been disappointed in with any of the 383's I've built over the years. I can't say the same for the 350's.
For me, it's a 383 or nothing.
Huhhhhhhhh 350s are really nice motors as well!!
400
Might as well build a 4" stroke, roller cam motor, vortec or aftermarket heads with a modern combustion chamber
( not Edelbrock or copies) cam to match rpm range desired and compression to match the cam and fuel
Fen exactly 💯
Thats what i did Dart block ,4.125 bore, 4in. Stroke crank,6 in rods, wiseco pistons , AFR heads , 427. When its time to regresh .030 over , new slugs, presto a 434. A Howards solid roller. It is a torque animal.
@@ronniecox109 way to go I do not see why anyone would build a 383 now that rebuilt stock 400 cranks cost as much as a new 4", cast cranks work fine" and you do not need to go nuts on the rods and pistons if not road racing or marine. WE bored the 62 327 block to 4 1/8 you could bore 283 1/8 so we said why not. Spent a long night at a gas station with a quickway sleeving 16 holes
4in stroke has been done on 350s but are few and far between
@@gordocarbo Chet Herbert did hundreds of 4" stroke 6" rods,, injected gas and fuel, blown fuel and gas and street using 283,327 and 350 block He also built several 452 cu in 4 1/4 strokers and won top fuel at the 62 AHRA Nationals at Cado Mills Texas with the 452s and top gas with the 400s The light Shubie blown fuel car was competitive until the larger tires allowed the hemis to hook up
Blocks are the limiting factor as opposed to the 60s stronger, raised cam, larger cam tunnel, larger bore blocks are available
I like 4"stroke builds I was part of the 62 team 4 1/8 bore on 327 -350 blocks split cylinder walls BTw AMC was better
I built a 700 horsepower 383 stroker for my 69 Chevelle I'll be giving it to 350 shots of nitrous nice video
My early 383's I used Scat and Eagle stroker cranks and I have had both of the break, very poor quality, for many years now I only use Callies/Howards or Crower crank and rods, you can buy a Callies or Howards rotating assembly from Competition Products and they will internally balance it for you at a very affordable package price, these products will never fail you, I build these engines for road course racing, I have had a couple people swap this LT1 stroker in place of their LS power.
Great test to show how much more torque you gain. Like to see 400 added in show where it stands.
Same here I'm getting ready to build a 406 would like to see how they compare

I just finished watching your 408cid LS stroker video and started craving one for sbc. And look, here it already is :)! Thank you Richard! I wonder how much would a basic budget stroker kit increase the price tag of sbc rebuild?
Last I checked you can buy an entire rotating assembly for $900. Cast crank, forged i-beam rods and hypereutectic pistons. Plenty strong for a naturally aspirated build or a low boost build. More like $1200+ if you want a forged crank and pistons too.
It can quickly become a difference between what quality of the machining is on the budget parts, most kits with say Eagle or Scat for instance usually need machining to get them good.
@@PSA78 SCAT better
@@jmflournoy386 Than Eagle, yes. Than anything else, not even close from what I've seen. 😄
Are these SBC HP/TQ numbers directly comparible to the L96 6.0 tests you have done Mr Holdener? Same dyno and such? Your tests of mild, dish piston rectangle port 6.0's, with very mild cams CRUSH the sbc results.
Ls has superior heads add a set of aluminum heads the sbc will close the gap alot
A lot of money for only 125hp. Depending on the target power range someone wants. You done a video on the vortec 350 and boost. 600hp is easily attainable for the same amount of money as a stroker kit, without the extra from buying aluminum heads.
I like it.
Would the 351W/387W combo work with EECIV? Mass air seems like it might, but I am curious if speed density could be tricked into running it.
Yes, I'm cheap.
It isn't "cheap" per se, but Sringer performance sells their PiMP eec 4 replacement that is basically Mega squirt in a plug and play package for eec4. You can even pick batch or sequentially fired injection
@@AndyR1982 Yeah... $2500... It's a bit salty.
@@Heathh49008 , yeah but if i read right, Moates is dropping further support for the Quarterhorse stuff in eec4 so it may be the only way in the near future

Hey Richo.
Was the 405hp 350 kinda typical of an engine like that?
Not experienced with Chevrolets myself but It seems a little weak.
Did it have much compression?

Why not a 400? Or 406 to be exact
Ever think about doing a video comparing small block to big block same cubic inch engines? Like a 396 stroked small block to a 396 big block. Or a 427 sbc to a 427 bbc. Would just be neat to see them side by side.
Been there don that except at really low rpm BBC rules, it's the heads but think weight BBC also holds up in HD or Boats
I don't dislike the 350 engine I've had very good experience with them. But I've always wanted a 383 because I believe that if you're going to spend the to rebuild spend a few extra bucks on a stroker crank. I think scat used to sell a 383 kit that was almost a bolt in deal. It had cast steel crank and was 3.68 stroke and needed to have a. 040 overbore to make up for the smaller stroke crank. But it didn't need the extra clearance that 3.75 crank does. I don't know how much they are now but it was like 1150 dollars for the whole bottom end. Crank, rods,pistons rings and bearings
There are several kits on the market.

It is fun looking at these dyno sheets. I have a freshly rebuild 350 Buick in my daily driver. Mostly stock minus intake and headers. Engine just up and dies over 4000rpm. But even though it’s a cheezy low compression 350, I can rock a 28 foot flatbed trailer full of firewood with my 3.08 gears and 32 inch tires. Peak torque is at like 2000 and it still makes excellent torque at 1500.
Great video Rich, what is your preference when building a 383 using a 5.7" rod or 6" rod??
They cost the same
I'd do the 6.0 rod.
Any difference in power will be small. A longer rod might add some extra hours (longer life) on your engine run time due to less wear.
Is it better to build a 383 or a 427?
A 427 REQUIRES AN AFTER MARKET BLOCK
I have 67 camaro with 327. what can i do to this motor on budget build. It currently has a 3 speed manual transmission that i would like to change as well.
cam and springs
I wonder what max tow torque is possible with cheapish 400 sbc. I'm open to vortecs and tpi and maybe even cheap boost.
But, honestly I think I would prefer it naturally aspirated, reliable, and hope for good MPG. All I want is that + max torque.

put a sizeable solid cam in the 383 and watch it jump
Try a 108 lobe separation angle, should bring torque up quick and have more !
Had a custom 108 LSA Crane roller in my 355 and it was a beast(.615/.625, 235/245 @ .050). Rowdy idle, too.
The thing about 350's is that you already have the 3.48" crank
Thinkin about a 383 for my 87 k10.....can i use a stock...or close to stock cam.....so i dont lose power down low.....99 pcnt of driving is,1800 to 3600 rpm
something slightly bigger would help without any loss
Does it make more sense to put a 350 crank in a 400 block, or a 400 crank in a 350 block? Just curious. You get more cubic inches, but you have to make sure all the rotating stuff doesn't hit the block, and use an external balancer (and flywheel?) in one case, and in the other case, you have the block with the siamesed cylinders so maybe cooling is a worry... Just curious which is "better?"
most don't like to deal with Siamesed bores and steam holes-so 383 is more common unless an after market block is used
@@richardholdener1727 makes sense. Thanks. Looking forward to the 396 results. I first worked on my buddy's 396 that he put into a '63 Impala, in...1977.

No substitute for cubic inches I agree
You ask why not build a 383. I say why not build a 406? If you really want torque, how about TPI?
I have a chevy small block 267 what can I do to make it faster because it slows as hell....
Throw that into the scrap bin!
yes-boost
Small block 400 ?? Obtainable HP ????
350 crank in this block ? Can any one shed light on pros cons?
406 😄
Once you make it a 383 is it still technically a SMALL block? Small if talking cubic inches... I'd say the cubic inches pushes it into the Big Block range. So, just get the junk yard Big Block.. your mpg is going to be the same.
Add a superram for insane torque!
TPI and a cheap turbo setup for 700+ tq
Would a 383 still be good for a daily?
yep. plenty of 450HP 383s running around and they idle fine
I drove a 383 powered ‘71 Nova daily in the 90s and it was phenomenal. Horsepower may win races at the racetrack but torque is what you want on the streets. Small displacement engines need to be rev’d to be enjoyed. A fat torque curve will put a smile on your face at 1/2 throttle. I have built hundreds of engines and that 383 is still my all time favorite. Planning to build another in the future.
How is the miles per gallon on the 383 daily driver?
NO IDEA
I’m not being a wisenhiemer, I really want to know. Thinking about breathing new life into an old 350 with a 383
@@chadrowlett893 /the more the efficiency is, and the more power it makes, means it takes less throttle to maintain any speed.
Why build a puny 383 stroker when you can start out with a 400 SBC block, bore ity .030" and stroke it to a 415? I mean, if bigger is better, then...
383 All day everyday!!!
Could one do thecsame with an lm7?
383 is possible
@@richardholdener1727 yeah I saw some of your different ls 383 after..
Strangely enough the LM7 is the only chevy v8 one can get fairly cheap in Sweden.
Most v8s people want $5-8000 for and a later ls more than that.
The lm7 can be had for around $2500 so its the only sensible offer in my mind..
I have a pair of double hump heads and a aluminum intake and a holly 600 CFM carb and would it be alright to build a 350 Chevy engine with a 279 degree cam stock push rods and rocker arms how would this combo work out for a budget build for my car
279 advertised duration would be fine, but it will need springs too
