I decided to build the best 4.1 block I have. It's an unusual 044 block. It seems to be one of the last 4.1 blocks cast. I already fitted it with a RJC girdle. I sent the main caps to RJC and they machined them for me and sent a shim kit. I just got a RPM 3.625 stroke 4340 crank just like the one in my spare motor. It balanced with almost no weight removal on the spare. Next I will need a set of H beam rods, 11-1 custom JE pistons, rings, wrist pins, and spirolocks. I'm in no rush and will get the parts as my budget allows. It will have a 4" bore to make rings easier to find. I tapped the oil galleries for TA allen head plugs. A few photos attached of the progress so far.
