Rattle between block and trans?

I get a lot of those in missing the tags, cardone is usually no issues, but no way all of the curves are the same 72-80. As long as it runs good right, now a 100% resto they want it perfect, just did one for a guy, bet he spent 2-300 on the core dist. The curve specs are in the fsm if you need to see them.

Whoa, $2-300? Whoa, : ) I am certain that you could most likely correct the curve in this thing. I don't know what I'm doing with that. I know it runs on a weight system right? But how to swap them out and what they should be??? IDK. If I got another Cordone Dist and sent it to you, what would you charge to correct the curve in it? Do you just need to know that it is going in a 1975 360, with a Holley 650, Peformer Intake, the cam specs, and headers? Seems like they would all cause it to be different than stock? If you would, how much would it run me, I would love to have the correct advance curve in it. It runs "good", but I'm sure it could be better. It seems like it is either too advanced to too retarded.

Thanks
