Possible New Cast Iron Cleveland block


Recommended Posts

That's his first cast so I am sure there will be further weight reductions. Also, keep in mind that there is a lot of machining left to be done in that block that will eventually reduce the weight. There are not even lifter bores.

I saw his post on FB, they're looking at a capability in the 4.20" bore range, with nearly 1/4" wall thickness. I imagine we'll see 450 CI engines without trying hard.

Good Cleveland blocks around here are like the proverbial hen's teeth, except there might be a few blocks still around, unlike hen's teeth! I once had a J code block, but sold it believing it was no good with rear drain holes. I also had an L block, but it had been cracked and welded, so I got rid of that one too. Now I can't find a good untouched block anywhere local.

That new block looks interesting. I wonder what the finished cost will be.
