Running a 3800 stall (4200 flash) converter in my '65 Belvedere. I'm currently launching at 2000 RPM and getting no spin on the tires so there's room for a harder launch. Question is do I launch at a lower or higher RPM to put more torque to the tires? My guess is to launch lower. Anybody know of a tech article that discusses this, what I would consider a very basic question? Akron Don Gallimore
