high compression 408 build

Work with Ryan at Shady Dell Speed or contact Brian at IMM (user ou812) for the right cam. Then once you get that figured out have Ryan put the right valve springs at the correct install height and go. When building an engine, especially one like the one discussed here, you need to team up with an expert because you will need help with rockers, push rods, retained/locks, carb recommendations ect. Why not hook up with someone who does this every day and knows Mopar small blocks?? I had Ryan and Brian help me put mine together its got punch and two years of beatings runs like a champ.
