i have 5000 saved up for a engine, 331, that i want to install into my 1990 gt. should i bore my engine over or should i by one thats already stroked? and if so any good deals that are out there cus i dont want to spend all my saved up money. still need to invest into a good transmission. lol
well i heard that u cant do any additional upgrades to the 347, like a supercharger or turbo. so i decided to do a 331 just in case later if i need more power i still have that option. lol
idk. thats wat i said but a few people said that the 347 is naturally aspirated. so idk. plus they said that the 331 option is the best bang for the buck. especially if i want to keep pump gas, etc.
a 347 stroker wont make high compression unless you have small cc combustion chambers in the heads... and the aspirated and naturally aspirated has nothing to do with the stroker kit, if your motor is just all motor no power adder then it is naturally aspirated and if you have a blower or turbo then it is aspirated...
I'd go with a 331 stroker if you want to boost/spray it later. 347s get really stressed out with boost, specially if its a stock block. I'd get a 347 stroker if it was a Man O' war block or something. I'm going with turbo, so I'm stroking my block to a 331, the block is weak as it is, I want to keep as much meat on the walls as possible until I can afford the $4K block tag. But then again its your car
