I've been eyeballing a boat in the classified with these engines and aside from if they may or may not have used 1075 parts in them, all I can find out about them is that they're 557 tall decks, H beam rods, HR cams.

Anyone know what heads they use.... and compression ratio ?

Depends what was kicking around the shop that week lol. J/k I have no idea

Thinking about picking up a nicotine habit????

post 2 nailed it....

That's the one....Love that boat, it's just that the azz end of it looks strikingly similar to the current boat, and while I enjoy
repairing drives, I don't like repairing my own....I doubt the'll take $ 30k less to rectify the problem

Dlange, your PM box is full.

I'm no help on the internals, but that is a good looking boat... git 'r done!

If I drug that thing home, I'd be looking for a new home

Last summer, I took my nephews down to PBC to check things out, checked out and climbed around that center steer 39 TGU that they had.

Get back home, the nephews start yakking about it, the wife gets wind of it,....first thing out of her mouth was "what kind of drives does it have on it ? "
...end of discussion

I would be very leery about any engines that came from Cobra/Randy.

Your wife knows more about drives than 50% of the people on here

And HERE is where that 30K would need to go to be all good!
