he said it has gaskets and stuff too...I'm liking the upgrade mojo...but that comes with replacing a bunch of other stuff..I want the stuff I have to work so I guess I'm going exact replacement. 4.3L...like the $850 one, 33,000 miles from a silverado...I'd say exact swap, like turning back the clock on the engine I have. Hell he may have some stuff still hooked to it, make my job easier..
I'd check into this Ninja. Also see if you can get him down on the price. If I remember, your truck is pretty much a base model isn't? Just go with the 4.3 for the cheap patch, and 33K, is just a broke in motor. Even if they didn't ever change the oil in that 33,000 you still have a like new motor. You maintain it right, from here on out, you should be able to 177,000 miles out of it if its a factory standard engine. Save your bucks, keep the better fuel economy, and less tickets for now, and then instead of upgrading the engine, upgrade trucks at a later date. JMO
and what I'd do with a base model standard cab truck.
