2002年2月16日 · Do a search on 496 or 496HO. I think the 496HO has a forged crank, different cam, and chip is programmed differently. I believe that the main differance is that the 375 has a cast iron crank, which I don't think is balanced. The cam is also differant, WOT is 4400- 4800, the HO is 4600- 5000. The HO has better internals, from what info I can get.

2007年5月20日 · raylar kit for the 496 will make between 500 and 600 h.p. I think the original question is "what's the difference between a mag vs. HO, other than the 50 hp". I think it's a different cam and different ECU tune, but I'm not sure.
