Now i have a new question motor is built and done right now its cr is 8.5:1 i was wondering if anyone has gone low compression n/a i want to eventually put a turbo on it but don't have the money in the immediate moments so i look at and think of just putting headers on i know the power wont be there but was wondering if it will affect motor function by going that low at n/a

I ran around on my 327 quite awhile before finally working toward the turbo. It comes in at around 9:1 after figuring the head gasket. No problems and actually put down just over 310 to the rear wheels on a nitrous cam.

Not that it makes a difference i was just talking about it being ok and all now the question would be what injectors? I was thinking with the turbo to be at 60# at least thats what the guys at jpc told me so at n/a would 42# be ok? Or could i use the 60s and be at 50% duty cycle?

60's would be fine it just needs to be tuned correctly. I have 160's in my car and it idled at 1% duty cycle with no problems. Buy objectors once, take it from the guy who has bought almost every size they make. Lol
