Sounds awsome mate.
They are a good motor, Dad has one sitting in his garage for a project one day. keeping it low revving by the looks of that? 4800rpm isnt all that much.. but the 450-500hp you are after wont be hard to get with what your doing to it. they guy that dad bought his off said it can comfortably see 6000rpm. He's also got a 460 sitting next to it, and physical size there is nothing in it, they are a massive motor! |

The cam is actually the second largest hydraulic cam CROW CAMS offer and is supposed to rev out to 6,000 (makes power up to 5,500). These are the figures they put down in the catalogue, which even the bloke working their said was 'CRAP' don't take any notice of it.
The engine requires a bigger cam with more overlap to bleed off some of that static, otherwise it will detonate itself pieces. |

Ahh no problems, just read 4800rpm and thought, wait a minute thats 'soft' lol..
power to 5,500 and revs till 6000rpm sounds a bit more like it  Dads one from last I heard was making 380hp, and it only had carb and headers from memory(dosnet have headers anymore). I havn't heard of these motors detonating from compression issues, there you go! learn something new every day.. im kinda hoping dad doesnt do anything with it, so I can get my hands on it and do something with it lol. Cant wait to see how this all goes, make sure you keep us updated ;) and pics are good to lol |
