I have a friend who own a machine shop here in Maryland, he has 2 or 3 454 gen IV blocks std bore out of cars or trucks. He hot tanks, mags, pressure checks, line hones and taps all holes. He doesnt deck or bore and hone because he doesnt know what you have for pistons and what your combination is. I believe he gets $1500.00 a block. Just cant find a good non corroded block anymore.
