318 Stroker Build

yep- what heads- you can't pick pistons or cam till you sorta pick them all together - and exhaust
have you read the 318 porting thread at the top of the forum page?
late stock heads? magnum or magnum style heads? Enginquest Iron heads etc 318 heads ot 360 LA heads like late 318 4bbl?
start with a stock converter or the HP/340 converter and get a baseline -- internal or external balance
what do you mean lightweight connecting rods all the stock rods weigh about the same big question what rod bolts and are you going to have the rods professionally resized when you put the new bolts in? pressed pins or floating pins? if floating bronze bushings or steel on steel
headers or stock duals? (can't pick cam til you pick together)
