I spray about 115 shot

I have a 221/227 561/569 114 comp cam, jet hot LT, lanes duals, lid, filter, S3, Ported heads on the way(flow around 290)

I had a PT4000 but it blew up with only have about 9k miles on it, so that is out of the question.

I have a nice built tranny, a couple of options I was looking at

PY3600
SS3600
Maybe a different brand of converter

 

Why do you want to change the PT4000 converter ?

 

b/c the pt4000 blew up and it is not fixable, it scares me to get another yank

 

Then I would suggest TCI 3500 or 3800 would be a good choice for you with a small shot of nitrous.
