All of are's are done with girdles and good parts...All are kept to 6700rpm or less..

The one we have not done is a 440/543....A 4.5" crank is a big crank in a stock block.....I would love to hear feedback on one of these


question, I have a aftermarket "b" block, what is the biggest stroke crank i can get to fit with a 55mm cam? Can you get a 4.5 crank to fit? I would love to have a 572

Thanks
