for those who are running a 383 stroker

[truckincurt]

hey guys im in the middle of a 383 build and i was wonder what u guys are making for power and what componets you are using thanks alot

[71STPSDE]

Mine dyno'd at 400+ horsepower, but what I like is the 440 foot lbs of torque. I bought mine as a crate motor. It has some vortec heads, 9.5 to 1 compression and flat tappet cam.

I am considering doing the same. Are you building your own short block if so what kind of crank, rods, and pistons are you using? Are you using a roller or flat tappet cam? Heads? Intake? FI or Carb?

[CoggedBelt75]

Eagle 4340 forged crank
Crower 5.7 stroker sportsman rods
Arias 8:1 blower pistons
Isky hyd blower cam
World Sportsman II heads
Weiand 671
BDS 8 nozzle electronic bug catcher controlled by FAST ecu
No numbers on this yet, but even before the blower, had a good seat of the pants feel and is driven daily on pump gas. Without the blower, and with 10:1 pistons, same heads, Comp Cams 292H series flat tappet cam, Edelbrock Performer Intake, and 750 holley, she chassis dynoed at 426 HP AND 456 TQ.

I bet you will see somewhere in the neighborhood of 600hp from that motor...

im goin to build mine from scrach as the tatto on my back says DIY OR DIE lol but i got a early 70's 4 bolt main 350 .. i want to use eagle rotary componts but alot of ppl have ben telling me to run scat but they cant tell me y every drag racing team runs eagle not scat in my oppion eagle is better but any ways i was thinkin about 11:1 compression with some alum dart pro one heads full rollor cam /rockers u name its goin to be rollor and the worst thing u can do to a motor is over carb it but f carbs i was thinkin about tryin out the new accel mullti port fuel injection idk yet as u can see its no low budget build i want it to run and i want it to run like a raped ape

For the money you'll spend on the retro rollers for the cam, you could get a vortec builder that's already setup for a roller valvetrain, IMO.

[swb85]

^^^Agreed. I wish I would have done that with my 383 instead of spending the money converting the older block.

ya vortec heads would be the easy and cheaper way to go but vortec heads dont flow the best

Not that I'm disagreeing, but I’m curious as to what you meant. Stock vortec heads run more flow then P/P 202 cast heads. Now I know you can buy heads like Dart’s but you’ll also spend two to three times as much money. So is that what you meant?

As for your question, I also bought a create engine. It’s the 383 stroker from Blueprint engines (Marshal engines built it). Dynoed at the crank 405hp 440tq. I have to say that I’m way pleased with it so far. I still haven’t tuned the carburetor yet so it has an issue when you first hit it. But from 1500 rmps to 5500 it’s putting a hurtin on that ape!

[truckincurt]

yes thats what i ment... i would be happy with 400 tq but my crazy ass is lookin for like 550 well im hoping... i just want to sit at a stop lamp and punch it without tuching the brakes burn them threw 1-2 before hitting 3 and taking off.... after the motor its gointo be latter bared and tubbed then body work and lowering it 2.5 in's at some point... its a good body allready so thats y im not worring to much about it ... but at age 20 its all about the need for speed lol thanks alot guy for your input keep it coming!!!!

[78BO]

Gotcha,

To be honest I thought I would have that with this engine. But I can't get this (bad language) carb tuned. It smells like it's running rich. I've followed the carb instructions and nothing is working. But I DO NOT know anything about carbs. I need to find someone close that does. As for 500+tq, I was thinking after the warranty is gone I might change the heads and cam for these, 350-60989 E-Tec 200 Cylinder Heads with the 350-2207 Performer RPM SS383 Hydraulic Roller Cam. They claim Performance results obtained on a 383 ZZ383 short block with 9.5:1 compression. I bet if a person bumped up to 10-1 you could get a little more juice out of it. But that's to far down the road right now.

Hi everybody,

right now I´m collecting parts for my 383 project as well. I will purchase the eagle kit from summit, already balanced (B13405-030) with the new EDELBROCK F-Street heads (180cc), singleplain manifold, Holley street avenger carb 650cfm and summit headers.

The heads are the new "budget" heads from edelbrock, - but I´m not sure if its worth the money ??! Maybe I should go for those vortecs ??

I've seen Vortec heads support 600hp on a 406 SBC with a little bowl smoothing work. Vortec heads are pretty much the best out of the box heads you can buy. It's not all about flow unless you're running massive cubes or turning over 6500 RPM. The 170cc Runners and the 1.94/1.6 valves flow plenty. The big power is created in the runner velocity and swirl properties. Over heading an engine is worse than over camming it. Err on the side of caution and always go with a smaller head than you think you need, you can always have a little taken off, you can't put it back on so easily.

They're telling you that because Eagle Rotating assemblies are expensive. Much more so than Scats Nodular iron set. Scat makes great cranks, the fillet radius is just as much as anyone elses and the ductile iron will take a beating and keep on going since it will flex and absorb the impact a lot better than the Forged Steel cranks will. The drag teams use the Forged cranks because they're running 14:1 or more compression with blowers and methanol injection systems, they need the stiffer Forged cranks. The thing you don't see is them pulling those forged cranks and scrapping them after 2 or 3 competitions cuz they're cracked. If you're smart, you'll run Scat on a street engine and leave the forged stuff to the blown or NOx injected engines, cuz you're just throwing $1500 into something you don't need, money that could be spent elsewhere, like creating another 50hp. Just a little friendly advice from an old 2wd Modified pulling truck and dirt track car engine builder.

^^^And in my experience Scat has much better quality finish work than Eagle does. I've seen eagle rods & cranks that needed a ton of cleanup work right out of the box, scat stuff never has that problem. I run a scat crank/rods in my 383 and scat rods in my nitrous fed 370ci LSx.
