What do you think my 1965 361 is making for horsepower now?
Stock 361 pistons, 383 magnum cam, 452 heads with valve job, M-1 dual plane intake, 1 inch 4 hole spacer, Carter AVS carb, points distibutor, Mallory ignition box, stock manifolds, dual 2 1/4 exhaust pipes, Dynomax super turbo mufflers.. the motor was freshened by chrysler, we used the 452's to have the use of hardened valve seats..

The 383 Magnum made around 330-340 hp with Hi-Po manifolds. You have to figure what your mods would do for the Maggy, and subtract for your smaller displacement, compression ratio, and log exhaust. My guess would be around 315hp. What do the rest of you think?
