What timing cover are you using with a 7.3 inch damper

You’ve shown me more timing cases in your post than I’ve ever seen

I’ve been in Chryslers for over 30 years. I know what come out with what, that car in my profile picture makes over 600hp, and I built it.
I just want to know what timing covers are we using with a 7.3 inch dampener
Not sure how I'm being passive aggressive, but what ever!

For someone who has "been in Chrysler for 30 years" you don't seem to know much.

Have you considered contacting the damper manufacturer and ask for what they recommend?

They built it and so there must be a cover available that will work.

Lastly many of us have no problem using used parts.

Have a great day.
