i appreciate the response. Cant find any info on the actual block with hp. everyone says "i am thinking of do this set up....ect"....I am only looking for max 450-500 (unless i get happy with it) to the wheels on pump gas (if able to). but i guess i will have to see. I guess that means i need to get some mahles (any places locally or know where to get them for the low?) ........and that also some good info with the press in sleeves..... are you the one that everyone says send the head to you/ your dad for head work?? .......what setup are you running? if you don't mind me asking and any numbers?
