Thanks, mine won't have quite as much torque at take off, lol. Running a 350 4-bolt with Vortec heads and 650cfm 4bbl but matching it with an M23 4spd with a 2.98 first ratio so that I can launch the 3.07 rear and get some mileage. Mostly plan on cruising. I just don't want to cruise and shake at the same time.
