One dropped valve / shattered piston and a bunch of metal shavings later I have an engine that needs rebuilding. It was a 454 / 400hp Mark IV engine. It has been warmed once to my knowledge. If anybody is interested It is in Smyrna ready for inspection.
I also have 2 holley 750 DP and stock Merc intakes.
The other engine was still fine with only about 200 hours but I pulled it out anyway and replaced them both. I am also looking to sell it and taking offers.
