The base engine was a 250 inline 6 cylinder. Also could be ordered with:
292 Inline 6
307 V8
350 V8
396 V8
250 ci,305 ci, 350 ci, 350 ci (Diesel), 379 ci (Diesel) (1982).
It would be the 700R4
Yes. Chevy actually came out with a diesel s-10 pickup. They are rare but you can do it.
That would be the 4L60E
Yes, if it came from the factory with a converter.
My 1970 gmc 2500 came has one.
The 1970 Chevy Chevelle came with a 6 cylinder, all the way up to a 454 V8. If you have the 396 or 454 you need to use Premium Fuel. All other engines can run on Regular.
16 inch rims
302, 351, 360, 390, and 427
Some already came with a/c, so yes.
That truck came factory with a 700R4 transmission. And that has overdrive in it already.
The one that came in it works quite well.
