FBO Curve And Limiter Kit

I use them all the time for curving and limiting totals, and they work.
It is the ONE available performance upgrade available for the Mopar electronic distributor.
(use one light spring in the place of the big spring and it will give you a quicker curve all in by about 2,500 R's and set the plate at the 18 degree slots)

That will get you able to do around 16 degrees on intial and 34 total (approximate)
Of course you can also limit it more and use more initial, or lock it at zero if you ever had the need.

Is that what you wanted to know?:D
