Re: [Classic Mustang] Indications of a bad pressure release valve

Well, keep in mind, that's $750 for just the machine work. The rebuild kit
will be in the $500 range (assuming I need pistons), and there's always
another $125 or so for cam/lifters, plus another $100 or so in
miscellaneous stuff you forget about.
