Cool build.
Here's my .02 for what it's worth.
Use the F cam with it's 108* lobe centers, it has less overlap.
I've seen stock rods live for short periods with stupid amounts of boost - IF YOU DON'T RATTLE THE MOTOR... but they are NEVER a good idea with
much any boost. However when used with decent gas (110 is good) <8:1 cc'd static compression and 15lbs boost, stock timing, I had one go for a long time with no issues, so it can be done.
Just remember that cheap gas will get REALLY expensive in an instant.
It has a way of spitting your newly "S" shaped rods out through the case.
Big bore low compression has more torque than small bore but make no mistake, low compression sucked for street riding until that little gauge points to it's happy place.
If you shim up the cylinder base much you get into oil supply issues, like having to make special O rings and support spacers. Do-able but not advised. I used 5 base gaskets and the cam chain still fit. Barely.
Make sure you have enough fuel flow through your petcock (or better yet fuel pump) if you intend to see much boost for more than a few seconds, it's surprising how quickly the float bowl empties and black death appears on the cylinder walls.
