Does anyone know the STR of the 3 Vig convertors, the 2800, the 3200, and the 3600. I looked around online and can't find it.

I know the Vig 3600 has the reputation of excellent short times without a lot of MPH. Given two equal cars with 3.23s and full bolt-ons and a mild cam, of the 3 Vigs, which would pull the hardest on the highway?

I know the 3600 is the least efficient but with the higher shift extension, would it still out pull the 2800 and 3200 from a roll?

Yes. 3600 is not that big of a converter and you will start higher in your powerband than you would in the 2800. I do not even know why someone would bother with anything less than a 3500 stall. That is like running shorty headers IMO, waste of friggin money. I went 4400 w/2.2str on my daily driven stock internal LS1 before the motor swap. I'd do it with this motor if the tq wasn't too high.

Oh, and I am not positive of the str on those converters either but their website should have it.

Well the Vig 2800 IS a great convertor. My previous car went 11.98 with bolt-ons but stock manifolds, and a T1 cam. I cut 1.64s with that convertor, not bad at all. But I do agree I'll probably go with something just a touch bigger.

I think the 3600 will be the best from a roll. STR is something you'd have to contact PI about. I remember reading their 2800 for an LT1 was like 2.5 but I believe STR can be tuned to any converter; that is, I'm not sure that STR is locked to a particular one. I know for Yank, the Super Stock line has a special stator, and that I believe you could order any STR for any stall you like.

I'm sure if you give PI the specs' on your set-up they'll tailer you a good converter
