CHevy 350 and Muncie SM465 Trans into a YJ...your thoughts?

Hey guys/gals:

I am just in the process of deciding to swap out horses. I don't have enough of them rattling around in my engine bay and I'm kind of a hill billy...which means my anemic I4 isn't loud or quite obnoxious enough. I would like some opinions, however.

For now: I'm intending on leaving the NP231 tcase in tact...and throwing a 5.7L 350 v8 in there with a Muncie SM465 transmission to compliment it. This tranny is a good pairing both for the 350 and the 231. Anyone have any better ideas? Thoughts...suggestions...anything will help! I'm in no hurry as this is about project number 8 on my "projects that will take a while and I'm having a hard time finding motivation to start any of them, but probably should because my Jeep is a pos" list.

I appreciate it! Thanks!

Lol. Well thank you jsaw. I myself have put plenty of 350/Muncie combo's in...Chevy's. Just never in a Jeep. I don't know if the 465 marries up with the np231 as nicely as I think it will...I'm just wondering if anyone has placed this particular combination in their YJ yet...if there were any inherent problems that I'd rather know about now....

Both Novak and Advance have writ up`s on this swap. It might be a good idea to Google them and check it out.
