what kind of power gains will i get from running a cobra intake?
306
flat top pistons
f cam
190lph pump
12* of timing

 

If you still have the stock heads on the car, 5-10hp. If you have aftermarket heads, 15-20hp

 

If you have stock heads, you wont gain much(15-20rwhp) But if you have good flowing heads, id say 20-35 horsepower, especially in the higher rpm's. If you have stock heads, putting the intake manifold on wont be worthless, as it will help the 5.0 breathe a little up top. you will lose some low end torque though.

 

well
heads arent too far off
i just gotta find something to fit with the f cam and flat top pistons without having to get them notched

 

I'd get it. Takingthe intake manifold off again for the new heads isnt that hard

 

okay then
what about heads
i know the Twisted wedge heads fit on a stock bottom end but since i have flat tops and a decent sized cam will they still work without notching?

 

Because the TW's have 2.02 valves you will have to notch them. GT-40 heads should clear. I'll have to look it up

 

okay then
what does it usually cost to have pistons notched? just a rough estimate

 

Acutally, you may not have to notch them with the Twisted Wedges because of how the valve is positioned. Call Trickflow and ask.

 

yea
i might do that
thanks for the info bro
