I have two intakes. One is a ported lower gt40 with Downs Ford box upper. The other is a ported Typhoon. I'm wondering if it would make much of a difference between the two with my set-up. I have a 5.0 with stock bottom end, performer heads, cam, and Vortech running 12lbs. What do you think, coin toss?

I think the typhoon might make a little better power on the street (low end)

The gt40 will have alot more torque and probably about the same hp. So I would go with the gt40.

I think the downs box will show a loss of torque, however your SC should make up for it.

My bad....I didn't see you were running a Vortec. Go with the Downs Upper/GT 40 intake!

That's what's on the car now. I came across the Typhoon and the price was right so I picked it up.

I have a 70mm throttle body on Downs now. I have a 75mm with egr spacer that was given to me with the Typhoon. I'll put that on the Downs. Normally I would think 75mm would be too much but with the blower I should be OK.
