I think the people that ended up with a usable Ritter block were lucky.
I have a 340 mains 59 9.6 deck it seems like 1 problem after another babbit bearing bores are all tapered in at the rear of every hole had to have the cam tunnel trued up
Then went to assemble only to find the inner cooling holes have about 50 thou seal with 18 Bolt cometics
These are the untouched original casting holes
Using a Felpro 1008 you can see into the water holes it dont even cover the edge of the hole
Kent said he would check it out that was the end of that never come back obliviously he knew the block had serious core movement so had the block plugged on the 2 holes then refaced that was that problem solved .
Reassembled screwed all the ARP studs to the bottom of thread then backed off slightly 2 of the studs ripped out at 90 Ft lbs not deep enough also the oil pump mounting surface was way off level & the pump wouldn't fit.
Another issue was the centre thrust cap was 8 thou thicker than the bottom so when the caps were tightened it would lock the crank tight.
This is from his new machine shop in Indiana.
Some things to look out for if anyone is thinking of building one of these engines
Anyone else have these issues on the lastest run.
I just dont feel confident enough to waste a heap of good parts in this engine luckily i have a new tall deck R3 to use
