LM7 into an Astro work van

Not for the inexperienced engine swapper. I've done quite a few swaps, and this one was a PITA. 01 LM7 from a Silverado into a 97 Astro. Still putting it back together, but here it is running open manifolds. Runs like a bat outta Hell.

gotta take the whole motor out to replace the alternator and spark plugs, but it's cool. LMAO. There's barely enough space to work on the damn 4.3L V6...

@i811st Actually it's easier to work on than with the 4.3 because the fan shrowding and air intake crap isn't in the way. Alternator is very easy to get to, especially since I have replaced the F body brackets with some TBSS brackets. Spark plugs are a pain to relace, but no worse than on the 4.3.
