How much power can I get out of my 454, I want to do all the right stuff to make it last a while. Make it a 468. I have the 781's heads still deciding on the bigger valves or not. They are bare casting right now. The motor I want to use was running when I took it out of the truck. I suppose it would be better if I tore down the motor before I took it to the machine shop. I'm going to try to get by with 2000-3000 dollars. How much power do you guys think I can get out of it. I don't really want to much compression around 10:1 to keep away from the race gas. The motor also needs to pull 15 inches of vacuum for mud race rules.
Any ideas or suggestions on good cheap power is appreciated. Thanks
