ok so a 5.7 has a displacment of 345 cid so now would that be labled 350? I ask in regard to if i was to put displacment in retro on side of scoops. would i put 345 or 350? i guess i am asking is a 5.7 considered a 350? everything is leters now days what happened to good old cubic inches? are we getting that old? lol even when i had my 5.7 GTO never got a straight answer.
