ty for the info.

i just thought i'd be able to help out a friend and buy his engine he wasn't using. but it sounds like a v8 swap is too much trouble unless the van had originally came with a v8.

i suppose if the current engine ever gives up the ghost i'll just get a rebuild on the 4.3 rather than a v8 swap. really its not a lack of power, the 4.3 vortec has plenty of power for my needs. heck going off my seat of the pants dyno, it seems to have more power than my old 1996 g30 with a 350 in it. probably has more to do with the gearing than anything though.
