A guy at my work wants to sell a new in the box GT40 Ford Motorsport intake (upper and lower) with a trick flow spacer for $550. I'll probably offer maybe a little over $400, but anyways, how much Horsepower would that intake give my car.
Specs (at least that increase power):
'89 GT 5.0L
1.72:1 roller rockers
70mm throttle body
MSD ignition
I'm also going to put on the 1 5/8" shorty headers w/ the 2 1/2" offroad H and Flowtech Stinger cat-back and put on some fairly heavily ported heads with slightly larger valves, all gasket matched. Any ideas? I just wanted to get an idea, i'm guessing 30hp but i don't know if it's worth the $$$.
