I have a 34 Ford with a tired 283/301 that I am swapping out for a ZZ3 350 crate engine. I noticed that the old engine was tilted about 5 degrees to the rear when sitting at ride height and I am thinking I need to readjust the motor mounts to bring the new motor level. Do I really need to go to all the trouble or will the new motor be allright at that angle or will it just create problems with carburetion since I am installing the Barry Grant Six Shooter, three two barrels, on the new motor. Help!
