The tac is right now and I turn 2500 rpms at 50 mph with my 4;56 rear end. I have had it up to 57 mph which gets about 2800 rpms and I think close to the top. I am going to a show with my 1948 chev 1 ton panel with a 235 and want to know if 2500 rpms will be fine for a 3 hour trip. Thanks for any help.
