wats up guys....one of my buddies has a single cab 07classic 5.3 chevy. Fully bolt on minus pulley his best time was a 14.0 with a 2.1 60ft...he recently installed a 3200 converter that brake stalls at 3600 at the track. Converter feels great, a little on the tight side but feels good since I've personally driven it. Yet, his best time has been a 14.0 with a 1.95 60ft with the converter. What could be wrong??
