273 rev monster combos

I'll throw this info out there & you can do whatever you wnat with it. I built a 273 way back in 1976. It had 10.5 to one pistons, >484-284 cam (as best as I can recall) Isky springs, windage tray, Mallory dual point distributor & coil, Offy single plane manifold, Holley 3310 carb, stock bottom end (no balancing or rod work, just full groove mains), stock oil pump, pan & pickup, 1 5/8" full length headers, 10 1/2" aftermarket clutch & flywheel, 4 speed & 3.91 gears with Sure Grip. I usually tried to shift at 6000 but I know it pulled right on up to 7000 at least once & it never complained. Had no low end to speak of but the 3.09 first gear helped there. It wasn't a tire fryer but it was a screamer.
