Sorry, brain fart at 4:00am in the morning
Gaz64 Yes you are right. The other question is we don't know if the camshaft was just dropped in or was setup to camshaft manufacture specs.
The other things are this
this motor is a 521 I think he said, how big is this camshaft?? That's a nice size 460 over built. Retarding the camshaft will kill alot more than 20 ft of torque. more in the range of 40-60ft. It may only kill about 20 HP down low. A small camshaft in a 482 motor with .600" total lift kill 35 ft of tork in the bottom end with a 4 degree change. Remember that these camshafts are designed for smaller motors. 70-90 more cubes is alot of extra room to fill. Kill the timing also will do the same thing. Rick L.
