Closed Decks
WoooHoooh
Closed decks are here. 391ci the easy affordable,fast way. Sleeves on hand no waiting. These are very strong thick sleeves you can Turbo or Nitrous these blocks. Also corrected some proprietary common LT5 issues that our LT5's have. We can go up to 4.155 on these. Looking into making some MLS gaskets for the big bore (4.155)

Re: Closed Decks
Pete,
That's great news!! Just in time for winter projects. Those sleeves are steel, I assume. And, no milling out the bores either!? AND, using the stock crank, or is it also offset ground? Gotta ballpark idea on the turn-key price? Man! those blocks would really put some lead in the FBI's pencil at the US-41 (CPCC) drag races!! That trophy might as well take up a permanent home with us!

Re: Closed Decks
Great work Pete!
Can't wait to see the results of the first motor. No doubt it will be a screamer.

Re: Closed Decks
I believe it was a fad going around the engine design community at the time. For low rate high end engines like the LT5 it allowed the complete precision finished Nikasil coated aluminum liners, pistons and rings to come as a drop in package from one supplier which in this case was the German company Mahle. Mahle was also supplying many of the other sport car engine builders including Porsche and Ferrari. I am very well aquainted with Mahle from my many years with MTU. All of the high performance marine diesels we produced had pistons from Mahle.
