Hey there crazygn, when you switched over to the V2, did you hook a vacuum line back up the the modulator can on the TH350 tranny??? If so, where did you hook it up to???...You might also be actually applying boost to vacuum modulator, which could cause all sorts of problems...If you put a bigger cam in on the new setup, then you probably don't have enough vacuum for the tranny to operate properly...
Your tranny may be the WHOLE problem...There may not be anything wrong with your setup, you really ought to mothball that TH350 and put a built 200-4r back in it with at least a 3200 stall converter...
A -54 turbo ain't gonna spool worth a crap on an 1800 stall converter and with not enough vacuum to the tranny, your gonna have all kinds of performance problems which may make you think it's your motor...
You really should post ALL of your mods in your first post about the problems you were having, rather than being all p*ssed off for weeks when you can't get your car to run right...
Not a flame, just trying to help out, dude...
I hope you do finally get your car running right, it should run like a raped ape!!!
