I have been working on the cam and cam bearings... Conventional cams have different size bearings with the largest bearing in the front of the engine. This likely eases installation...

My question for the group - Would you machine the cam bearings the same diameter for this small scale? It seems that it may be hard to install the bearings unless I stagger the diameters slightly.

Well boys... 12 hours from now I should be able to handle the first draft of the LS7 block. Functional coolant and oiling systems... all holes are center drilled to be tapped. The block isn't 100% quite yet, but getting close.

And here it is... I am actually surprised the print came out so well. For the number of undercuts on the part, it's not too shabby!

Very nice. Is the print qualiy good enough for aluminum casting?. It looks like a wax pattern.

This one was made form ABS. I could print in PLA and do lost PLA casting when the design is finished. I am still watching videos from Aonemarine on this and learning about his casting method with vacuum assist.

Sure is nice to have the model in hand to reference.

It looks so cool. It must be satisfying to hold the design in your hand and to be able to look at it in the real world.

It sure is! Even when you know all the dimensions, it is always a wonder to hold it in your hands. I was surprised at how "large" this block is. The block is 5.500" long.

You are a funny man Aone...

After reading back through my last post, I guess I could have phrased things a little differently.
