I'd tell you for sure but I don't think it is on this generation of block. I'll revisit this at the end of February when I get back over to the shop where I'm building this pig.
I can verify if it's fixed or not on this early version.
I’m not a high rpm guy and only shifted my R3 block 422 at 7000 rpm for 3 years and 6800 last year. I’m curious to see what the bearings look like in it.
