Thanks for the input, Jim. I had totally gapped on the possibility of an epoxy sealant. Good thinking. I think I'm going to give up the 4" bore to another joe and stick to the new hemi bore instead. Putting a 350 crank in the Rover is enough firsts for me. I figured I'd use the deck plate for that shortblock for certain. Easier to solve the deckheight issues and get a decent rod ratio. It's also a bit more practical for the T6 aluminum bores for the sleeve to sit in.

I'm going to look more into the epoxy idea.

You know, I don't think I'd use epoxy. It has a tendency to age and crack. The right-stuff sealant has a very aggressive grip but it remains flexible yet way tougher than the silicones. It is not only a good sealant but an excellent adhesive as well. Once you start using it you're sold.

I might consider building an engine such as this sometime later on. I'd have to find a suitable block to start with though and I also think I'd want to do something to strengthen the head and main bolts. But first I have a 340 to complete.

LOL! Me too! ha ha. Good point, Jim. Here's a link to what you were talking about. I just assumed it was some type of epoxy. I guess not! Thanks man.

You could just use another head gasket under the deck plate also.

You could, but the sealant will help anchor the plate to the block, it is really very strong. If used for pans and valve-covers for instance, a knife has to be driven around the flange to separate the parts. Use the caulking tube though, the cheese-whiz can puts bubbles in it and makes it weak and porous.

Let us reveiw? The sleeve is "a". flanged and drops through deck plate. "b" welded to bottom of deck plate. "c" neither, floats in limbo ,between two head gaskets, in a wiggly sanwich "d" is all magically held together with, "super slicone" like a fresh pair of boobs , on the runway ? I am mystified, roverman.
