need some advice on a good converter for my 408 TransAm I have a th350 with a TCI 4000 now (more like a 4500)and on motor I do fine but when a spray I think I'm blowing threw the converter. I have a vig. 3800 if I go back with a built 4l60e or would it be more of the same? it's a full(over) weight TA with a TSP 408 and 4.10s as of now but thinking of droping back to 3.70's

thanks in advance
