now that im putting 4v heads on my gt block the compression is going to drop more than i was thinkinh.. is it still safe to spray at this low off a cr until i have some money to but a some boost?

and another side question.. will the gt exhaust fit cobra manifolds?

way back when, when we didn't know any better, a lot of us were spraying at way lower compression than that with no problem's. you'll be fine if you choose to spray it.

the mid pipe should bolt to the 4v manifolds, you just cant use 2v exhaust manifolds, you'll have to use 4v manifolds.

spray and compression arent related
they work hand in hand

nitrous does soo much better on motors with more cr

but 9-1 on a pump gas motor is more than fine
