Does anyone have a list of Chevy engine casting numbers. I'm trying to find out what "mystery" motor is in the Blazer. This was a hack job when I bought it.. was diesel converted over to gas. Any help is greatly appreciated. And BTW : The new guy "PHYTE" his wife is about to have a baby. He called me today.. we're trying to get a local Austin K5 gathering going.. Just thought I'd pass on the info.. Not only did Phyte get a new baby (blazer) his wife is having his baby.. It's better to have it and not need it. Than to need it and not have it !
