I have 2 model A engines both rebuilt one has a turned down model B. Crank in it is there any difference from the outside do not want to open up the engines.

If the rod journals haven't been turned down, then they would use Model B rods on the crank, and may have made some oil pan dimples for clearance of the rod nuts. Otherwise I don't know how you could tell the difference.

If it is an early non counterbalanced B crank with the rod and main journals turned down to A dimensions it would essentially be an A crank. If it is a counterbalanced B crank, pull the oil fill tube out and look in there, you should be able to see the counterweights.

The B or C crank with B rods will clear the A pan without dimpling if you use ARP 12-point nuts, otherwise the pan must be dimpled like the B pan is. As Carter says, you can see if it has the counter-weighted C crank by looking in the fill tube hole.

It looks like you pretty well have it figured out.
If you are just looking for bragging rights, close it all up and tell people it has a Moldex billet crank in it.

Thank you all. have never had a model B crank in hand. David

Lack of serial number was the way to find the model A with the 32 crank it. LOL

You probably already know that there were three Modle "B" cranks: the earliest had no counterweights, the second had swedged-on weights, and the third had counterweights cast as part of the crank. You can remove the oil filler neck from the engine block and peer down into the hole to tell which crankshaft you have. You may need to turn the crankshaft over a bit in order to see the counterweights.
