Race Ported Gt40 Intake Manifold on 2040-parts.com

Here we go, this is a very great deal on the ultimate street/strip manifold for the 87'-95'EFI Ford 5.0 V8. This manifold has a fully race ported lower (not just basic mild port work) and a partial ported upper that gives you the best of both worlds. The upper has been partially ported to eliminate the restrictions in the runners, TB opening and curves. The lower has been fully race ported. The lower has an average flow of 297 CFM and with it's upper bolted on top , together it's average flow is 261 CFM which is more than the top 5 aftermarket manifolds in it's class.

This manifold will support more than 540 FWHP with supporting parts. Most heads for the SBF don't flow 261 CFM at the max lift of the cam so this piece will work very well with just about any combo.

With this manifold you won't lose any of the low/midrange torque and power that you loose with the aftermarket ones but will make more average HP than the top 5 manifolds in it's class. This manifold is great for the grudge cars or the sleeper cars because you can make great power but have a stock look. A motor doesn't care what brand name is on the manifold it only cares about air flow, CSA and runner length and if you get those right then you make more average HP And that means a much faster car!!!

Ported to accept up to a 75mm TB but will work with any size smaller and with a runner size CSA of 2.25" (the System Max II has a 2.47 CSA but only flows in the mid 240s CFM). With an extremely broad power range from idle - 6,500 RPM with the proper supporting parts. This manifold is hard to beat and is drilled and tapped for the ACT (air sensor).

A great choice for the 302, 306, 331 and 347 size engines.

This manifold has more than 20 hours of professional porting and flow testing done to it so it is proven  with solid data and track times. It will make more average power from idle to 6,500 RPM than the top 5 manifolds in it's class. I have one on my full weight  91' GT with heat, AC, power everything, AOD with 3500 stall and full interior that runs low 11s on pump gas with no power adders.

If you were to take a stock GT40 manifold and have it ported to my specs by another Pro porter you would pay over $750 plus the price of the manifold. The price of these manifolds will not remain this low for long so don't miss out on this one by waiting. Get the jump on it before your buddy does!!!!!
