AMC 360 Engine Build - Cam Swap and Engine Specs

Combo Four: Lunati "Small" Cam
For you guys who want to run power brakes and have a milder idle, we swapped in a smaller Lunati cam with 221/230 @ 0.050 and 0.484-inch intake/exhaust lift with a 1.6:1 rocker. It pulled 12-14 inches of vacuum at 800 rpm and made over 450 lb-ft of torque starting at 3,500 rpm with a fat peak of 470 lb-ft at 3,900. Wanna burn rubber sideways on the way to work? Here you go.

Peak HP: 437.2 @ 6,000
Peak Torque: 470.8 @ 3,900

The "little" cam and the dual plane conspired to make the most average torque and horsepower at the lowest rpm with the best vacuum at idle and least popping and complaining on the dyno. Street combo? You decide.
