Thanks guys. Maybe the 4.3 isn't a viable choice then.

I asked about swaps some time ago and J Lemond volunteered some info about the 3.5 isuzu - I'll have to search and find that thread. Seems like the 3.5 is kind of spendy, so that's part of the hesitation with going that route...

I'll search around the forum and find my old thread as well as others concerning the 3.2 to 3.5 swap. If anyone has those threads bookmarked, feel free to post the links!

Thanks...
