question about a setup
for a while ive been wanting to actually build a car, more or less from the ground up. i figured id sell the 03GT i got now, get some lill econobox and get myself a 5.0 to tinker with.
so as im looking around i decide i wanted a 347 stroker, i come to realize, well with that... adding a supercharger may be a bit on the uneasy side. ive heard some bad things about the combo. so anyway from what ive read the 331 is a better stroker for a s/c. mind you im not going to supercharge the thing right away, but its always nice to have room to add on.
i came across this DSS engine. ive heard really good things about this. the shortblock comes with forged pistions and rods... the crank however isnt. the longblock comes with 205cc AFR heads. i wanted 225cc AFR so im not sure if ill get the longblock or not, still need some research on that. the 225cc's i think may be for the 347 stroker and the 205cc's for the 331... im hoping i can put the 225cc's on the 331.
anyway! i was curious. DSS states this block is built for 650hp n/a or with a power adder. they basically state that its built to take a super. im just curious if that IS safe with a non forged crank? i know a stock LS1 crank can take 1500hp so im not sure if a forged crank is really needed.
alot of people tell me the only things i should be worried about are the rods and pistons being forged. just curious to what kinda opinions you all have

RE: question about a setup
the 331 should be ok for a supercharger running under 10 psi, but if you go any higher your gonna break ****. if i was you id drop a 351W in there. they are a much stronger block and you wouldnt have to stroke it. it could handle the supercharger and youd get another couple cubic inches. most 5.0 parts interchange with a 350 and they bolt right up to stock engine mounts. 225's are pretty much all out racing engine only heads, and theres no way a 347 would need them. if you go stroker or 351 the 205's should be plenty.
i think DSS sells 351 blocks too and if your set on having a stroker you can stroke a 351 out all the way up to a 427. if your going stroker/sc id definitely recommend the 351W.
good luck!

wow... after looking into it. a 357W longblock is actually cheaper then the 331 stroker block i wanted... haha go figure... i didnt even look before, figured it would cost way to much.... thanx =)

RE: question about a setup
Ok where to start, first off tom and crew at DSS have sucked you in on their cnc stock block marketing gimmicks. Anything over 500hp at the crank is a crapshoot on when the block is gonna split in half. The last thing you need to worry about is the crank, atleast dss gives you the main girdle that will keep everything in place when the block splits. As for the 331vs347, whatever you read is nonsense, the 347 is fine.

+1 on the 351W
the 351 is the engine the 302 shoulda been, they're stronger than a stroked 302 and usually cheaper to build up too.
you also dont have all the block flex that the 302 has probs with, not only causes
the block to crack but is also know for causing head gasket leaking problems too.
If you're starting from scratch the 351W is hands down the way to go.

also consider a turbo over an s/c, they make a ton more power.
