Horsepower guess?
I'm taking an '87 +.040 shortblock, sticking a cam in it, and fresh bone stock Magnum heads drilled for the LA intake for my truck. I need torque, not HP... well, that and rods that dont rattle :D. I dont really care about compression at this point. You can go out of you mind worryign about things, or just accept it and go enjoy it. There's always the NEXT engine to build...
