I recently bought a 28' checkmate with a whippled 502 built by Wildcat performance engines mated to a Bravo 1 X
first trip out on the water it grenaded itself eating most of its pistons.
what I'm trying to figure out here is how I can rebuild the engine with all the good parts I have (block, crank, rods, cam, rocker arms, heads, intake, and Whipple kit)
what parts do you recommend? ex. valves, (block would need bored possibly) waiting on machine shop.
I'm sure I cannot build/ buy another long block for a reasonable amount of $$$ and slap the charger on top
looking for some insight. not having good luck with my first boat and would like to change that.

any pics of the "grenaded pistons"

Won’t let me post pictures here yet. Few people I talked to said the rings weren’t gapped for boost so it blew the tops of the pistons apart.

Just post 8 more small posts to burn throught the mandatory posts and post the pics

Where are you located ?
