72cc E-heads with 1.77 exhaust added ported to around 324 or so at .700.
Comp solid roller 270 ish @ .050 intake and exhaust. 440 lobe, 1.65 rocker.

Johnny,

That is one bad GTO you have built there. I hope my Firebird runs that hard with the roller cam I bought from you a while back when I get it finished.

Johnny,

Did you do any tricks to the 12 bolt rear. I am going to use one that has been pretty highly modified and take a lot of flak that it will not last.

Robert - I don't have a trans brake so all I have is footbrake Data... I have the regular Richmond Street gear I bought used off of PY. No mods to the rear other than welding the axle ????? and using Moser c-clip eliminators and a rear cover/girdle. 33 spline Moser race axles. I don't worry about the rear in the car at all...

Thanks- well I shift at 7k so the only way I could get it to buzz those RPM's was to put allot of spring in it. I had some 580lb springs and could not get it to rev past 6600 rpm. Changed springs, shift at 7K and it picked up about a tenth. Hoping to put a glass hood on soon. This should pick it up a bunch. Right now the carbs are only about 1/2 in from the hood. That plus the weight of this thing is killing me.
