240 HP cracked block question

[DavidWilliams]

Is in a 1994 VIP,Yamaha 5.7l. Still starts and runs, but bthe lock is definetly cracked, you can see it on the outside of the block. Where can I get a longblock or shortblock for it. Are the blocks any different from automotive blocks? Thanks in advance.

1 option would be a GM Goodwrench crate motor for a 1994 Truck........<br />It's Pretty Close to a Marine block,+ Will Work, with a change of coreplugs(steel to brass).............<br /><br />Or, a Junkyard Bare Block from a 1988 to 1995 Chevy could be refurbished,+ then install All the parts from Your Motor........

So it doesn't have to be anything special. Will I need to use the same heads that are on there now?

Is Iowa Park Tx. anywhere near Saltwater,..... Or do you boat in Sweetwater ??<br />Is the Yammie Freshwater, or Raw water cooled ??<br />Are you looking for a 400hp Rocket,.... Or a 250/275hp Dependable ride ???<br /><br />An Engine is a "System" that you can build to do What Ever Purpose you Need..........<br />Try to find a copy of Dennis Moore's book, Small-Block Chevy Marine Performance...........<br /><br />The Answers to All of your Questions are in That book.............
