The shift from 1'st to 2'nd was at 14 mph on my speedomiter, 2"nd to 3"rd on my speedomiter was 24. We also confermed that I have a posi. rear end. I am going to chech oil and put in 30 wight royal purple,also check lift and I dont think it has roller lifters but I should check. To check this can I use dial indicater on top of lobe? Should it hang up on top of lobe longer, with it's profile? Thanks againe for all help.
Get a flash light and look through the push rod hole in the head you will see the lifter and the intake and exaust lifters are connected with a fulcrum you cant miss it!! if you see the lifters connected you have rollers!
