Just built 451 stroker for my 68 Cuda (4spd, 3.55's), 440 source kit, Eddy large chamber heads, Engle hyd flat tappet cam (special grind K56/K58 on 114 centerline), Approx 10:1 compresson. I've got a TM6 w/ Holley 850 on it now, but would the RPM air gap yield more torque & better performance? I'm also thinking of mililng the heads for more compression or switching to the smaller chamber eddys. Want the Cuda to be a hot street car that won't see the strip too much.
