BTW, I'll again add that I'm not saying the diesel thing sucks; I just think that it's a little over-glorified today.

The 292 in stock form is rated @ 153 net HP @ 3,600RPM; no problem holding it wide-open there until the sun burns out. It's a truck engine, and that's what GM designed it to do.

The 4BT normally makes something like 105HP @ 2,300RPM from what I'm reading; it's also a truck/tractor engine, and can also do that until the sun burns out.

292 wins hands-down here IMO, as it makes pretty much 50HP more than the 4BT does--a 50% increase in power!

A jacked-up 4BT will make more power than the 292, but it also might melt it's pistons out pulling a long hill running wide-open. Likewise, you could also put a turbo on the 292 (or otherwise hot-rod it) and push it until you start finding the weak links. Just my opinion, but those are my thoughts on the matter as of right now.
