You think I can fit a Big Block In there? I know i can install a Small Block, If id get a 350 i would get a Manual Tranny and Change the Engine mounts and also i would have to modify the radiator fan shroud im assuming

 

Anything is possible. Just depends on how much money you want to spend.

Being 2wd simplifies things as well as broadens the possibilities.

You would want to just go to an electric fan setup to save space and cut down on the headaches.

 

I Would Love to throw in the 572 Chevy Crate Motor. I Know its overkill but I had a chance to drive with that engine and its amazing. I could get that and throw in a new tranny coupled to it. With that i would not need my PCM would I? Its Carbed or DoI still need a PCM?

 

Different transmission without computer control and you no longer need the PCM. You would have to redo the dash though.

 

Well Ill either completely redo the 4.3, rebuild and upgrades or ill just get a 350 Fuel Injected Crate Engine Turn-Key From Perfomance Unlimited. Cost About 8K for the Whole Turn Key. Drop That In an then ill just modify my 4L60E if it cant handle it, or sell that and get a manual Tranny. But i mainly would like to Rebuild the 4.3 and then get the manual tranny. My Last question is how much is a rebuild of the 4.3 usually go for? Rough Estimates will be good if your not sure thanks
