Cam tower difference
What is the difference between cam tower 930-105-110R and 930-105-111-2R? Are they interchangeable for a 3.0 motor?

The earliest of the towers was 901 part# and they were opened for the 4 bearing cams. After a while, late 79, they became 930 part numbers until late 88 then they became 964 casting number. All attachments are the same for the oil lines and bearing sizes.
The PET doesnt show the difference. Bruce |

ajwans,
The 0R cam towers I have can off an SC 3.0 and it's 4 bearing. Could you be mistaken on it being 3 bearing?

Sorry, I'll edit my post, I didn't read your full part number,
I was refering to the 901 castings. You have 930 parts. andy |
