For mostly street use, on a 233+/heads setup, would I be able to really tell a difference? I am thinking of buying a used Vig, have it restalled/rebuilt, and then selling mine when I have it installed (I don't want to drop the tranny myself), so it would be the cheaper fix, thus this option. If there is going to be a big difference though, I may buy a TCI or Yank.

 

for a 4000+ stall I would do a TCI or Yank and not a Vig. I ran the 3600 in my car when it was stock internal and it did pretty well, but i wouldn't really recommend it for the H/C setup you are talking about.

 

How big of a difference can you tell b/w the stall you have now and the vig?
