thanks guys. That one article definitley has some nice tips that I didn't know. However its more based towards an economic build. I dont care if I gotta run race gas and only get 1 mile to the gallon though. I just want to build the nastiest motor I can for the money I have and to be dependable for about 9 months of weekends out of the year then pull it and freshen it up. I notice one suggestion was 10.5 pistons. Why not go all out with 12.5?
