I know it has been asked a lot but I have looked and only found builds using the roller motor. I want to keep my current block which I believe has the date code for a 74 and e7 heads. What are my options? On a bit of a budget build. The motor is a reman with only 1500 miles on it which is why I don't want to switch. I believe these have a taller deck then pre 1971 blocks. Could I swap pistons and re use rings to up compression along with a cam? Already have Lt headers. Dual plane intake and a summit 650cfm carb w/electronic choke and vacuum secondaries. Any help would be great
