I know this is a Mopar forum and my Mopars are running pretty good. I just wanted to ask some basic questions about an American V8s. My son has the engine out of his 1973 Grand Am with a 400. Being the block is probably a mid seventies what's the easiest dirt cheap way to make lots of torque? He is not asking for help but I thought I might suggest something while the engine is torn down. He's a college student so he's really squeezing every dime.
My 1973 Grand Am came with a rebuilt 455. The previous owner said it was a very mild build which scares me since I don't want to put something in the car just to yank it back out because it's dog. Remember we live at 7,500 above sea level which is big power robber. One thing I thought of was to have the heads or the block shaved down to increase the compression, although I don't know how much that costs or if its even the right thing to do. Everything I see on the net is let's build a 750 hp Pontiac so it's not much help.
