Padre, you mentioned you had a built GTO before this car. What size converter did you run in the previous car? Reason I ask is, I've been thinking that 3200 would be the smallest converter I'd potentially run, also thought a 3600. In the old LS1 4th gen days a 3200 stall was not very noticeable to me. I used to run a Yank TP4500. I did run a 4800 and then a 5500 stall in my last 4th gen, and the last converter was... unstreetable.
