for some reason I seem to remember Callies coming up in the conversation. Maybe I'm wrong.... still confuses the ever lovin s##t out of me
they do they had 8 instock when i got mine ,110 l/c
I have a 112 but would love more.
The cam in my R3 motor is from LSM and it has 115 LSA. I have no plans on using NOS so I think the motor would be happier with around 110 LSA.

Apparently the block can't be bored out to a roller using a CNC talk to QMP they can do it it just can't be done with a mandrel type boring needs a 90° Head because of the number five journal is so small And stupid me I have all these race manuals I just looked in the first one and found all the necessary measurements

Well..........that changed the way I look at things. I also thought that all 48 degree blocks used the same cam bearing bore on every journal , but apparently the 48 degree R-1 and some early R blocks used stepped bearings. I would have thought a mandrel would work too......sounds like it gets involved. Do you need to bore four , then re-set for #5 ? One more operation and the probable tolerance stacking would have me thinking long and hard.
