Depends what you mean by "ride quality". If you are talking about stiffness or harshness then you solve that with spring rate and shocks. So that isn't a big problem. Depending on how much work you are willing to do you can either slide under the car and adjust the shocks for street driving, and/or change the spring rate when going to the track.

If you include noise in the ride quality bucket then you'll have an issue. The Cal Trac setup has a bunch of moving parts which tend to rattle around while driving. So the back end of the car will sound like a bucket of bolts when you hit a bump.

Either you don't have Cal tracks or you need to look under your car immediately.

No headers helps a lot.

No, they are different between big block and small block.

A couple words of warning, I talked to this woman at length about this set up and agreed to her price and promptly sent a check only to be contacted the next day and told she retained a lawyer and the sale was off as I offended her by agreeing to her purchase price. She seems to be an unstable person.

Call made to owner sale pending.

As of today 67* for Friday and 60* for Saturday.

Carls ford parts.

Doug, as with most FE parts its about timing.
