big block

Looking for a Gen VI bare block either stock bore or max 0.030" over. Bought a boat "not running" found out why. Trashed the block in the process. Ready to go with rotating assembly and machining just need a new bock. Hoping to get the boat on the water soon!

I have a Olds 455 Hardin Marine engine I’m looking to sell, it runs but it started smoking and I’m swapping it for a rebuilt motor I have. I’m asking $400 it’s only the Long Block; heads and block for sale

I recently acquired a 1991 Fibercell jet boat with a crate 502 in it. When I turn the key to the on position the fuel pump starts running continuously. The fuel pump is wired directly to the power distribution strip near the starter. What is causing this? If Im correct the pump should only run...
