Headers and intake made no improvement on the dyno. So I hooked up a vacuum gauge and took it for a ride. Screaming in third gear, it was making two inches of vacuum. Card waay too small. I then installed a Carter BBD 2bbl, and it then made only 1/2" vaccuum. It really came alive, but I haven;t had it back on the dyno since.
Results of earlier dyno runs:
One bbl made 54 hp to the ground at 2750. Very level from 2500 to 3200. Came up to 56hp with the headers and power flo muffler.
Torque max 122 ft/lbs at 2,000, up to 125 with the mods. Drops on a straight line to only 30 f/lbs at 3500...
