That car had a 4.56 rear and a 3000 stall. It ran very well and I shifted at 6000. I now want to put this motor in a 71 Chevelle to use on the weekends for street use with maybe an occasional strip run. Question is: the 71 Chevelle will have 3.73 gears and a 2500 stall. Should I keep the Magnum 280H cam, .230 dur @ .050 and .480/.480 lift, or switch to a smaller Voodoo 60102 or 60103 or even a Comp XE262H or XE268H cam ? Any suggestions????
I would run try to run a cam that favors the exhaust side by 6 or more degree's.
A good example would be something like a comp. cam xe 268 .477/.480 lift and a duration of 224/230 at .050.
Also your carb is to big.
Try a 600 at the largest for a carb.
