Before I weld in the new motor mounts and the transmission mount on the crossmember can anyone advise what the preferred front to back pitch of the SBC engine should be? I have it sitting at 5 degrees now on a level floor but the frame is bare with the exception of the cab shell. Still have the under bed gas tank and bed to install. If I raise the transmission more to reduce the current angle I will have to modify the floor of the cab for clearance (no big deal). What is the optimum angle for the engine and trans? Thanks for the help.
