Mark,
Regarding your thread choice for the oil block, do you have a -10 "O" ring seal porting tool? Probably not but I'll bet you have a 1/2 NPT tap. I am not a real fan of pipe threads but a -10 port tool is probably $50+..
Looking good, the flywheel retention and location devices look good for at least 350HP+!

Hi Rex,
I do not have a "unitized" -10 o-ring port tool, as you suspected. I do have all the straight & NPT taps and counterbores though, so I could machine it in one setup per fitting, 3/4 separate operations, a pain in the butt. Not sure which choice will be made at this point. The carbide bladed -12 fuel injection rail drill/reamer/spotfacer combo tool set the shop back approx $220 . . . . . . for occasional use . . . . . . .
I also dislike NPT threads on race engines. I've seen too many "mechanics" "reef in" tapered fittings. The result is a cracked casting, often not repairable. Good judgment and the proper sealant prevents this situation. But I have given up on my personal crusade to "cure" "stupid". I'm sorry to report my efforts resulted in limited to no success, and only succeeded in raising my blood pressure.
In spite of the large size of the remote oil filter fitting block, because of the way the internal drilling(s) must match the existing oil passages, there is limited room for one of the fittings to extend into the adaptor block. I have not decided how to handle this yet.
On the crank/flywheel bolts and dowels, the pattern is from the original BMC so we could reuse the flywheel. It looks like "overkill" but BMC's with the 3.200" stroke are vicious "shakers". I've seen 1275 race BMC's without hardened dowels and upgraded bolts "shed" the flywheel at high rpm. Always bad news. The 999cc "Grenade" with its' shorter stroke was "less" of a shaker. And the Rover, with an even shorter stroke, will be even less so. But all Inline 4's have an inherent secondary imbalance, so best to be prepared, since there will NOT be any harmonic damper on the front of this crank. No room for fitment . . . . .
The crankshaft from Rody is really a nice piece of work, a work of art really. He did a fantastic job, especially considering all the changes that were specified. For anybody needing a billet 4 cylinder crankshaft, he should be considered.
