I never seen any thing but a forged steel crank for the A. The early cranks were called beaver tail , because of the way they were forged. You can use any A crank in your early engine.
 
Another advantage to the early block is the five bearing cam. If you are not going to show the car use the early pan. We run one on the 30 roadster. It give you access to the oil pump with out dropping the pan. That way you can remove it and clean the screen from time to time.
 
thanks George it is a beaver tail, I thought they were made from different material thanks for the advice
 
All Ford cranks, from the Model T thru the first V8's were forged. The beaver tail crank is a little lighter than later A cranks. The 5 cam bearing blocks were not as strong as later blocks, the real early ones had no ribs to support the rear main bearing. For Model A blocks, the later the better, as far as strength goes.
 
Just curious,
There was a steel crankshaft for sale at Turlock, seller claimed it was standard sized, there was a tag with the measurements but I dont recall what they were.
I understand being standard would be an advantage, but are the claims of better balance and strength true, the asking price was $100, seems it should have been worth more?.

Allen,

What is the number on the engine?

Is it the original stamped number or a restamp?

Hi Steve sorry for the delay just getting home the number is A628527 I just look it up make it out march of 28, I only see three cam holes and it does have the ribs in the rear, It is a great block std bore with no lip at all almost could go back std, no sleeves and no cracks,
The block was painted red so I thought it was a rebuilt one but after opening it up and taking it apart i think it was original the main bearing Babbitt almost wore the grove out of it. and had no shims left would you run the beaver crank are go with a later one thanks AL
