GT40P Header Myth
Just a basic video of my experiences with GT40P heads. Not all engines are the same with header combos so take this video with a grain of salt. Those are aftermarket headers so im sure stock headers theres even more room between boot/plug and header. Will this work on equal length shorty headers? Doing a 90degree boot is easy. Just take the 45 angle boot off and bend the conductor inside and put it into a 90 degree boot!

93 Mustang LX Dyno Run
93 LX 2.3 to 5.0 Conversion. Stock block 302 from my 88 GT, GT40P heads(unported, stock rockers, trickflow valvesprings), GT40 intake(minor lower port), Trickflow Stage 1 cam, Mac longtube headers, Mac prochamber, and Mac catback. Dyno cell temperature was 101 degrees and at the time coolant was spewing out the radiator cap from a blown headgasket. I probably could of hit a little higher with better temps and a sealed head gasket but I don't think I was giving up more than 10 rwhp as is.

My 86 Mustang 5.0 GT 500HP
This was my 1986 Mustang GT Hatchback. It's running a 306 Windsor with Trickflow heads ported to hell, custom grind high RPM Cam, Victor Jr. Single plane intake ported, Edelbrock 750 double pump Carb, and Hooker Shorty Headers. Altogether running just under 500 horsepower and 480 Torque. Top it off with the Tremec T-5 tranny and Posi rear end and it's one mean son of a gun. No longer have her. It is rated just under 500 HP If I still had the Dyno vid of the car I would put it up to shut the non believers up, but computer crashes take no prisoners.
