I am trying to get my 420A to 225-250hp. There are alot of things I need to go through, including rebuilding my bottom end, turbo kit, etc. I have basicly found everything I need with the exception of the fuel system. The cheapest I can find is about $800 on ebay. I was wondering if there is one out there slightly cheaper. ALl I really need on my engine is about 15psi, and I am already in the lower 5k range, and am digging pretty deep to get this thing done correctly. Also, what does a good volt-clamp run?
