Im about to get a Torque converter installed and shift kit. I was told to go with a 2200 TC stall custom..but isnt a stock tc 1800? Also was told if i go higher the rpms are gonna be high? I see people sayin to go from 2400-3200. Its a Daily Driver, I have 373s but ima swap to 410s and gettin longtube headers and in the future supercharged maybe vortech or kb.
