Thanks Jerry.... Just considering some options on the big block for the 'maro..... with a 3000 pound car, I'll take all the torque I can get!!!! I'm sure somebody has a good hydraulic roller cam out with some decent numbers for it.... Not sure if I will go 496 or 540 cubes..... What do you think, is this old Ford guy on the right track trying to put a chebbie together??????
