I'm heading to the dyno. This a 40 over magnum 360 with 4" forged crank,H beams, and flat tops. It retains the factory hydr. roller setup. The cam is a racer brown 248/252@50 with 608 lift. Compression came in at 11.8:1. Carb is a 950hp.It's also on E85. Intake is a ported M1 with a fully ported eddy magnum that flows 290s at 600 lift. Headers are a little bit of a compromise. They are a midlength with 1 3/4 primary and 3" collector. The cam is a little bit out there for the factory hydraulic roller stuff. I don't know of anyone running that much lift on a magnum set up. To control it, I'm running a nitrided PAC beehive with titanium retainer and a stud girdle.It's on the racier side for a magnum to be sure. I don't know really know what to expect.There's just not a ton of info on magnums with this type of build.
Place your bets boys!
