FBO Curve And Limiter Kit

Thanks. I am just wanting to see what different results people have and how they like it. Do you ever experience any binding or sticking of the mechanical advance mechanism?

I put mine on the 16 degree slot. I plan to run 20* initial and see what happens. This is in a small block distributor going in my 331 Hemi.

I have done a TON of reading and talking to some locals with early and 426 Hemis. ll agree that the design of the Hemi chamber makes it possible to run more timing early on in the RPM range. One friend runs his 392 with 21 initial and 16 mechanical with the two light silver springs. All in by 2100. No spark knock and he is at 9.6:1. I at 9.3:1. I figure with the camshaft I have and the Hemi chamber, I will be safe.

We'll see.

Sure, I think you could try both the silver springs to get the "all in" sooner but watch that initial with both in it because it will want to start advancing REALLY early in the RPM's (maybe even jump around a bit at idle)
Never had a sticking problem that I know of (I'd probably feel that easy enough) but it sure makes an otherwise stockish smallblock get snappier with those mods.
There was a seat of the pants difference in the amount of throttle needed to roll the car down the road.
It probably an apples to oranges comparison with a Hemi vs LA or Magnum though.:D
Those products do the job they are intended for in any case.
