The block is a 77. It's going in a w350 with an automatic and 4.10 gears. I want to build a torque motor. Im trying to figure out what cam to use. I was thinking about using the Hughes SEH1620AL-12. The heads have already had appropriate springs installed for big lift. They are 2.02 j heads. I will be running an edelbrock performer intake and headers. Any rough idea on how much power this could make?
