Working on the matching cylinder heads now... But there were some earlier attempts. I was able to get the bore spacing back closer to stock and have to rebuild the heads again. Not bad though! I love the details and thinking about watching this thing turn over.

Now you need to print the intake manifold. About how long did it taker to print the block and heads?

I think the block took around 12 hours. The heads were around 7 hours each if I am not mistaken.

Oh, I have been bad lately, neglecting my little project!!

I have been researching different casting methods. Lost wax/pla seems to be the best, but I still like the idea of doing core sand molds to pour blocks from! Maybe I am weird...

I am planning to send out for a water clear SLA of the block. I will then inject colored epoxy through the oiling system to highlight the oil pathways. I may even fill the water jackets with colored epoxy as well. This way, you could literally look through the block to see how these LS engines are plumbed. I may make the cam and crank from steel, add brass bearings, and try to make the engine spin over at low rpm for a desk top model... Sounds fun to me anyway.

Well, back to revising my cylinder head design...

Oops, posted in the wrong thread. I'm following along just watching. The SW models look good. I'd like to build a BMW six like a S38B38 one day.

I have printed a few of these off in ABS plastic. Really looking forward to trying lost PLA on this model to see how the castings turn out. I have water jackets int he model and they print fairly well with the ABS. I am hoping I can get that level of detail using vacuum assist casting.
