what would be better for boost 331 or 347 some say 331 (3.2500) some say 347 (3.4000) i always thought a 347 stroke was to large for boost and benfits more from na or nitrous and that a 331 stroke is perfect for boost just want some opions for building a bullet proof short block also what are some good companys that make stroker kits

what block?

if youre going 4 bolt block..

Big bore is going to be your best bet..

I would do a 3.25 and a 4.125 big bore 347.It would be good match for your 185's

too large for boost? who told you this?

it's not the engine that determines that...it's the tune/combo

once again...the engine itself, in your case, has nothing to do with that

i would go smaller..if it ever blows up, you might have a chance to rebuild it. and you can always turn the boost up

Are you using a factory block? If so save a ton of cash. Go 306 forget all the stroker stuff because after 450-500hp youre askin to split the block anyway....

yes dss also said if it does blow i kan rebuild it and have no problems and dan yes 4.185 is the biggest they recomend to go should be done in 6 to 9 weeks and came to $5086.95 total with everything and compression ratio should be 9;8;1 with my afr 185's

thanks for everyones help

Dammmmn 5k? To each his own but why wouldn't you have just rebuilt a f4te block?

Dss
Good luck... I've lived and learned I rather pay more and have an engine built local. I've seen and owned mail order engines and will never be down that road again

Those blocks are also a gamble at 700 hp.......
