Ok this is what I have running through my head. Stock block 351w, stock crank, light I-beams, Mahle pistons, Something along the lines of a TFS stage 3 cam, and I think I can get my hands on some 2v heads from a 400-M. This build is race only. No more than 6500 rpm. I already know there are other better heads out there but not for the money. I 'm pretty sure I can do this build for about 2k. What do you think?
