Re: New Timing Chain Issue

[Bill <Y1TopBanana73@xxxxxxxxx>]

OK...this is getting bizarre. It's confusing so I'll try and explain
it as clearly as I can...

I have a 66 318 Poly on the floor of my garage that I had Gary
re-grind the cam out of, and I have a 65? (stamped numbers ground off)
in my car w/ casting number 2468230.

The timing chain gears I bought fit the cam & crank from the 66. They
will not go in the 65? motor. The cam gear stops before the front face
is flush w/ the cam. The crank gear goes over the step-up on the crank
to about the half way point of the gear and stops.

The above statements would tell me that the crank on the 65? is a
larger diameter and that the crank gear from it would fit on the 66
motor...right? Wrong! It won't!!!

What the &%#@ is going on? Is this some kind of truck or marine motor?

I really want to get this figured out so I can get this thing back together!

Thanks
