One thing I have always liked about GM is that they tend to leave old bosses and mounting points in tact on new versions of their engine blocks. The bosses may not be tapped in some cases, but they are there if you need to use the block in a different application.

I wasnít planning on making a thread until after the molds were done, because Iím not sure how long itís going to take them. Heading up tomorrow to finalize everything and do a few minor changes. Once I have castings ready, one of our well known vendors here will be doing the machining as a final product, to make sure all is perfect before going out the door, more on that later.

Sounds like soon to be issues with the Siamese area between the bores at the big end of that range.

Fingers, you use some of the strangest terms describing these things (Siamese, hermaphrodite) maybe I’ve just never heard them but they actually make sense lol

No sir I havenít. Tho I think without researching I understand the concept. Maybe. I grew up wrenching on sbc and the first motor I built was a 440 with my dad. A lot of this is new to me. I usually spend about 2-3 hours each night just looking stuff up and learning things here and there. One reading why I love this forum. I actually read every single thread that anyone posts any given day. Learn something new all the time Iím assuming Jon is Fingers? If so, I know heís a freaking genius just from reading his posts.

Never messed with a 400. Mostly only 350, 327, and 305. But Iíll be doing research on this. Sorry to derail guys. Carry on. Ready to learn more

Thatís the easiest one to do out of all of them, we could do a solid billet block of 6061 😎. This 1/2 water jacket stuff is where it got tricky and requires a $10k mold😳.

Jon/Fingers, the larger bores were intended for the solid stuff, I hear ya 👍

Pretty sure the 6.7 Cummins is Siamesed in between cylinders and that’s why they have the head gasket problems from hot spots in the block. I guess you could see excess cylinder wear from slight warpage due to hotpotting? Doesn’t seem to be an issue with the Cummins guys though. Correct me if I’m wrong!
