Building a 383

[BKFT_HOTRODER]

I am building a 383 stroker, I don't have any knowledge about performace heads for 350's just wondering if anyone has any helpful input

Also If you know of a good site to buy stroker kits.

BKFT,
Head choices are abundant. Your budget and performance level are the limiting factors. What kind of horsepower are you after? Pump gas or race gas? What car are you putting this thing in? Manual or automatic trans? Rear gear? Street or race? (If it is to be driven at all on the street, it is a "street" car. Race cars live on the track or a trailer, for definition purposes)

Be advised, there are MANY stroker kits out there for Chevy. W like the Eagle, but there are others as good or better, depending on budget. If you intend to rev it past 5,000, or make more than 400 horsepower, I highly advise to get a kit with a "forged steel" ("cast steel" is NOT the same) crankshaft. We have seen significant problems with main bearings with the cast cranks. Also, if you're after the larger power numbers, get forged pistons as well. We avoid the KB "hyper-eutectic" pistons as they require too much prep to live, and aren't enough "cheaper" than a good forging to make the effort worthwhile.
Answer the above questions, and I can give you specific answers regarding the heads.

Jim

I've used these on a 350 with: roller cam, holley strip dominator intake, holley 750 vac secondaries, hooker headers, Flowmaster 40's (2.5 in and 2.25 out) Turbo 350 with shift kit and 3000 stall, 12 bolt posi 4.10. It ran 11's on 94 octane and was good for the street. It got bad gas milage though.
