Has anyone had experience with these? I am about to install one on my car and am interested in your opinions, thanks, Mike.

I`ve used one on a number of motors.
They allow easy timing adjustments.The motors seemed to smooth out some too.
You`ll have to lock out your distributer to use it though.
One thing i didn`t like about it was that you can`t use your vac adv.
For a street car that may or not be a problem.
I also broke a bunch of starters, infact it`s at the factory(Autotronics) right now having it reconditioned.
The 20* start/retard seems to be non functional.
Also the high speed retard seems to be OTL.

We`re going to put it on the 69 as soon as I get it back.

Love 'em.

Ran one until I splurged for a digital 7 programmable.......

It was much eaiser than what I have now.....now I need a damn laptop in the car.

Guys, thanks for the replies. I don't have vac advance on my carb, so that obviously won't be a problem. I thought it would be a plus since I'm at 5000' elevation and i will be taking this car to much lower elevations. Looking forward to getting it installed and playing with it. :cool:
