rhythmic vibration

But I like throwing money at my car! It's what I do best!

Actually, I'm fortunate to have a good friend who owns a garage. (He also owns '68 and '69 Barracudas.) He lets me work on my car there and usually helps out when I get stumped.

As far as the balance of the 340, I'm not sure. The torque converter is low stall and neutral balance, no weights. I've run the engine balance issue past the two best Mopar mechanics in the area, including the guy who rebuilt the engine. They both say it's internal, and that cannot be the issue. Here's a pic before installation.


I don't know if this helps, or not...
