Hey Ventura, sorry to hear about your low rpm issues. Get 'em fixed yet? One of the reasons I wanted to go with a GM set-up was to avoid those types of problems, yet as you can see BADFISH went that route and had problems anyways. Mind you it could simply be his too-cool water temps...
I 've installed the engine on the subframe of a donor truck which I purchased 2 months ago. I also cut out the cab section so as to allow me to use it for fitment purposes. 4L80E from PATC c/w Compushift controller is now sitting in the frame as well, feeding an NP241C off've a 94 3/4 ton pick-up. The subframe has had pretty well all the steering/suspension components replaced. Within another 2 weeks, my baby'll be pulling into my garage with a puny 4.3 for tha last time.
