Reply to "408c cam spec advice"

Toby,
The 408 in my 72 Pantera was built by McKeown Motorsport with CHI 225 heads and manifold and 11:1 compression and is similar to what you’re contemplating. It was patterned after one Mark did for the Engine Masters annual competition. The solid roller cam is his own design and specs out at 248 INT/254 EX @ .50 lift, 671/681 lift and 110 degree lobe separation. The engine dyno’s out with average flywheel horsepower and torque of 614 and 544 respectively with 681 peak horsepower. It has a heavy lope at idle and is about as radical as I would go in a street car. I only do gentle, rolling starts as I fear for the life of my ZF with 345 rear tires especially now that I know the ZF is only rated at 325ft-lbs input max torque!
