What timing cover are you using with a 7.3 inch damper

Where did I say I was setting up an early engine? Now this will upset you, I have an early 273 pump with this case on a 410, with W2’s works fine.(period look for the car).
This is why I disappeared of this forum for so long….
Yes it’s a smallblock damper
I DID NOT SAY you said that. In fact you didn't say WTF you have. How are we to know? Have fun and good luck.

I'll repeat that so you can read it. YOU DID NOT SAY WTF you had. But you already know everything there is to know about SB Mopars so have at it.

So far two of us have suggested you mill off the cast tab on the late cover and do whatever you have to do to plug the hole.
