IMHO....

Grab a reco 350, preferably a Vortec style.

Have the TH400 built correctly, 4L80e are great transmissions but the a 4L80e would run you more than the new engine and built TH400 combined.


Grab a new set of long tube headers and have an exhaust shop do the pipes and mufflers....why? Do you really want to lay on the cold ground and try and build an exhaust system?

IMHO, you dont need to get into the swap out and go electronic scenario...

Seems most of your problem is a tired trans and old exhaust.
