rebuild motor and upgrade horsepower

by Brian Richards
(Bedford, Indiana)

Hello, I haven't seen this website yet, so I am newbe on here. Anyway, I bought car from original owner, and he took good care of the car, but it has 173k miles on it, and I want to do a rebuild. It runs fine, and doesn't burn any oil, so it is a good motor to build up some. My problem is; I don't know how to upgrade the horsepower and keep everything within the operating parameters of the computer. In other words, I want to achieve around 500 HP, but want it to be reliable as well. I want the computer to be able to interface as much, or even better than it is now. Here is what I think I need to do: Bore cylinders .030, new flat top pistons, balance crank or new one, 3angle valve job, better springs to avoid floating valves, roller rockers, semi-radical cam, perhaps mill the heads if recomended, will I need a new intake? recomended fuel injectors, recomended headers, recommended exaust, and recomended computer chip.
Do I need to have my machinist get together with my computer dude get together and make sure everything is going to work out smoothly and dependably? I'm thinking 2k money spent. Any insight from anyone on here that has already done this, would be greatly appreciated. I just don't want to re-invent the wheel as they say.
Thanks much
