The short block is new with less than 1,000 street miles (balanced, blue printed, etc). I don't think it will have too much of an issue handling the power. I am using a Ram SFI billet steel flywheel and DFX Clutch rated to 650-700HP. Bell housing is stock, but don't think that is going to be an issue. Probably should go to an SFI approved balancer, but it is not just a strip car but is primarily a street bruiser. Their is nothing like the sound of a nasty solid lifter cammed' Mopar pulling up in the show, when surrounded by hydraulic roller cammed' Fords and Chevys :headbang:
Mopar recommends a pretty weak spring for this camshaft, but I have noticed some people using wild spring rates and wearing out the camshafts prematurely. The edelbrock spring rates for their valve springs on this car are 120# seated, and 320# open. I believe the comp spring setup that is recommended is only 328# open. Not looking to spin the engine to the moon, just enough to make good power by 6,000-6,500RPM. I can buy the cam and lifter kit for $188 shipped online so that is why I am leaning toward this setup, and also it has a very proven track record.
