NEW MOTOR TIME!!!
Ok well my npi motor crapped out. So im probably gonna go for a full pi motor swap i Just have a couple of questions. Will my headers still fit on the new motor? And will my tanny still match up? Also what if i went for a cobra motor? Would the headers and trans match up to it. Its a t45 and there mac lt's btw.

ok thanks. Were gonna get the head tested first to make sure i dont just have a cracked head before we go and buy a whole motor. If its not the head than the only other thing it could be are the rings on that cylinder so ill just get a whole motor. If its the head ill just get npi heads for cheap and getem port and polished and maybe some nice cams.

and if there is something wrong with is heads and he needs to replace them, the bump in compression will increase power. I don't disagree that correctly ported NPI's will flow the same as correctly ported PI's, but you won't get a pump in compression using the NPI heads because of the larger chamber...

Actually according to ford, the NPI heads were flow tested and compared to PI heads and the PI heads were superior. Even the ported NPI heads were still inferior to the stock unported PI heads. You're gonna spend the same amount of money porting the PI and the NPI heads but obviously the ported PI heads will be far superior so go PI...BTW, I got an aluminum block and some H-beam rods you might wanna check out...

WTF did I just say a**hole...I said according to ford...meaning that the manufacturer of the actual head says that the NPI heads do not flow the same as the PI heads...where are you getting your "backwards" information from...?? Oh let me guess, your reply will be that your buddy has NPI heads and he tested them against PI heads and they flowed the same right...?? And what will you say if I post the website for you to read it yourself...??
