Got engine back together this weekend and took it to the track. I changed the cam from .600 lift flat tappit to .672 sollid roller loosend converter and installed tranz-brake. It ran the same as it did last July. Same ET same 60 foot times same mph. I even ran it not using tranz-brake and still the same. Just as consistant, four 6.84's and a 6.83. Why didn't it run any faster?
