Before was basic bolt ons. After is GT40p heads, 1.7 rockers, Cobra intake with tmoss ported lower, 24lb. injectors, mass air conversion, 75mm pro m maf, alum. driveshaft, 340 fuel pump, 130 amp alt.,
All work done by Mike Post in Hampshire IL. The guy is awesome! He said with some tweaking and an 80mm MAF there are some more ponies there. And maybe a SCT chip in my future?

That's awesome Bob! Congrats. Throw a cam in there and you might see close to 300! But probably not worth the trouble. You're going to install a blower next year aren't you?

Thanks Todd, It was raining yesterday so with lower humidity it might be a little better. Only problem now is approaching stops with the clutch in the idle drops to 500 and has died twice. My mechanic said TPS is set at .94. He thinks it could be loading up because it is running a little rich due to the BBK adj. regulator not going under 40 psi (and BBK pressure gauge is reading a false 50 psi). Or he said to check the line going from passenger side valve cover to throttle body. The blower would be nice and that is my goal. I'm sure I would also have to go down to a 3.73 gear or I might even want a 3.55.

I'm going crazy with this perfect weather for a vert and no time to make it drivable, but This Fri. I should get the upper manifold back on and should be good enough until I can install the new Kirban fuel pressure regulator. I am tempted to try a SCT BAMA 4 bank chip. I know a Dyno tune is better but this sounds like it will help with the Idle and low speed bucking and should add maybe 10-15 hp. Also I could have one of the selectable tunes for nitrous and since I have the kit in my basement I could do a safe 75 hp shot. So approx. 285 rwhp plus 75 hp shot with 4.10 gears, 5 speed, drag radials, and all the suspension mods I think I will be running mid 12 e.t.'s

Let off at the 1000' mark I was actually racing the guy in the other lane so didn't need to drag it all the way out

Very nice! I'm taking my 273 RWHP to Byron Dragway tomorrow. I'm hoping for high 13's. I just added two Flowmaster cats yesterday cause it smelled so bad, so I'm sure I lost a little hp.

Mike Post is a legend out here, especially with these push rod Windsors.
