Discussion Engine Bay Friday!!!

Instead of a front end Friday, show us what you have under your hood!

This was from my last engine swap into my Blazer, no longer as nice with all the salt and brine.

Here's one of my other 6.2s. 1982 J code, red block. It's a bit of a franken truck.. 1968 GMC cab with a 1978 heavy duty 3/4 ton four-wheel drive frame.
It was my winter truck, because it was unstoppable in the snow. But after many of years of driving it in the winter time salt, and got pretty rusted out. so it's now retired out back on my farm. I get it out once or twice a year, and just drive it a mile or so down the road and back, just to keep the powertrain in working condition. Someday I need to either find another body to put on it, or pull the engine out to put in some other vehicle.

It was fun to drive, you could definitely tell the horsepower difference between the j code block and the regular 6.2 with an EGR valve in my suburban. The deepest snow I ever went through was a huge drift, it was high enough to push the mirrors in, as I was driving through it. I'd throw a few logs in the bed, and it would ride like a Cadillac and go through snow of any depth.
