Re: 4.3 Swaps?

I would stay as close to the 2003 model year as you can. Somewhere between 2000 and 2002, a lot of the thread bosses in the blocks and heads were changed from standard to metric.

A 2003-2006(2004 was the last year for the blazer) will be a direct drop in. If you get one from a blazer, you may need to use the oil pan and pick up from your full size
