383 Stroker
383 Stroker I'm in the process of researching and building a 383. I already have a bare block, carb, intake, and heads. Now i need to match my assembly to what i have so far.
I'm trying to make 500+ HP at least.
Carburetor: Edelbrock 650 CFM
Intake: Edelbrock Performer
Block: 350 with 4 bolt main
Heads: Pro comp Aluminum heads with roller rockers. 64cc/190cc ( minor port work ) and stud guides, hardened valve seats, stainless valves, and angled plugs.
I need help obviously, with choosing a rotating assembly and what changes in parts that i need to make in order to make this hp rating. I'm not getting rid of the heads, so i need to work with those for now.
Are eagle products good to choose from?
Id like to do a roller cam and lifters.
This motor needs to be street able also
Where do i start????

i made 508 hp and 480tq with 383 on a engine dyno. edel brock victor jr. heads64cc/215 intake runner. single plane edelbrock victor jr intake with wilson carb spacer and 750 demon. comp cams 244/244 3000 to 6500. roller lifters and rocker arms.
you will need a 750 or better carb, different heads with at least 200cc chambers, and definitly a better intake than the performer. your previous combo would be a good 400ish horse motor but not near 500hp.
I have a 750 Holley, and i can buy a better intake. This motor is going to get a Hillbourn fuel injection manifold, but i don't have it right now so i need to make good HP on a good intake and carb for now. And im in the process of finding out what cam is needed for the fuel injection.
I have to keep the heads. There is minor port work done already and im going to have more done. I'm purchasing a roller cam and roller lifters. I read good feedback on Eagle products, so im going to buy a kit from them. Is it really worth the extra money for get forged internals?
This is a street motor so im not going to be abusing it like i would on the track. I need to achieve at least 500HP, so what ever i need to do or buy id really appreciate the knowledge. Google isn't much help either
I'm trying to figure questions out like,
-What company should i buy my roller cam and lifters from?? Comp cams?
-What length rods should i get?
-Are there any particular brand of pistons that i should look for?
The whole motor is going to be with ARP products.
Id like to achieve this HP rating at 6500 RPM range, or am i going in the wrong direction?
I got a quote to have my motor balanced, machined, etc.. and to have my motor put together the guy wanted $2000. Does this sound reasonable? Its my first estimate, ill call tomorrow for more.

If you're keeping what you have heres my advice on cam..
Comp Cams Extreme Energy XR274R. it's a 236/242 Duration with .570" lift or .600 with a 1.6 rocker. Use Comp Cams Endure-X solid roller lifters. Trans wise, this cam will appreciate a 3000-4000rpm stall. If you want GREAT power, ditch the intake a get Super Victor intake from Edelbrock and a custom built Pro Systems Holley carb.. it'll make life sweet. visit pro-system.com for the order form after you purchase the cam/intake..
I'm thinking it'll make 450hp if it has great exhaust and intake parts. Compression will be a factor also. Shoot for 11:1 and run premium pump gas.

I have a 650 demon for sale if you are intrested i was going to use it on my marine engine that i am building but i think i am going to go with a marine base holley to meet coast guard requirements. Pm me if you are interested carb comes in the box...
I agree with denny except the intake. for a street engine, def. go with the rpm air gap. unless its a weekend racer/fuel mileage and low rpm power not a concern. then I still think that might be a bit too much intake for that cam/power band.
I had a very similar cam in my Iroc basic 355 build (stock trick flow heads, torker II intake, 750 carb, cheapo 3000 stall ) and it was awesome to drive, and went 12.4's in the 1/4. prolly around the 425HP range. but mine was flat tappet solid cam. same 236/242 duration. could go little larger cam with the rpm air gap intake and a 4000 stall and have very good street manners and prolly very low 12's at the track if not into the 11's. roller cams are awesome if you can afford it. but for the HP returned compared to the extra cost, not worth it if your on a budget.

Here is the answer to all your questions. We already did the homework, all you need to do is install it.

i also found out that i have the 210 CC and not the 190 CC. Im still looking for deals every where. If anyone has leads to a good set of forged pistons, eagle H beams, or anything at a good deal. I have the funds, i just need a place to send spend it
look on ebay. there's tons of good deals. just make sure there not seconds and are backed with the same warranty/quality you'd get anywhere else. the eagle Hbeams were like $260 long time ago I found out after paying like $400 to one of our sponsors.
and the only good that intake and carb are gonna do you is breaking in the eng. where it wont see WOT anyways. then sell them off.

Heres my setup and I should be around 530-550hp and 500 ft-lbs.
Eagle 4340 6" H-beam rods (becareful there are 2 versions of these rods, they make a budget version for much cheaper and they are not 4340.)
Eagle 4340 3.750" Crank
SRP Flat top pistons 11.3:1 compression
Mildly ported with Brodix track1 heads lost my flow sheet but they flowed around 290 cfm @ .600".
Professional Products single plane intake, ported and gasket matched
750HP Holley carb
Lunati Solid roller cam 242/242 .592/.592 on a 110LSA with 1.6 scorpion roller rockers
Full arp studs and bolts
1 3/4" hooker super comp header
NOS big shot 400hp single shot
I figuire the 4340 setup is good to 1000hp.
