Cool swap man! Where are the exterior pics to show off the new stance? Lol. What pcm mount is that?

I cut and modified a stock mount from a 98 silverado,, I'll post more tomorrow

I am sure you know but that nipple on the radiator is threaded on the inside.

I noticed some are threaded and some are not, just my luck that mine is not threaded

Nice swap - I'm thinking about doing the same with a 96 4.3... how long did it take you once you had the majority of your parts and what was your biggest challenge that you didn't expect?

I didn't want to take apart the suspension on both sides of the truck, just to access the bolts to remove the frame mounts for the engine, just to have to put it all back together again. The V-6 frame mounts are plenty stout enough to use. I simply fabbed two basic engine block mounts, to bolt to the existing frame mounts. Piece of cake.

Nice job! I too like the better gas mileage out of the V8 vs the V6!

Looks real good! What a blast to drive huh? I am very very interested in your A/C setup....... I've been going 2 years now on 5.3 swap in central Texas heat with NO A/C!!
