if he wants to keep the orignal dist... use a elet one as a core and just pick up a reman points style one for around 30-40 bucks then drop a pertronix points conversion in it,I just did that for the 440 truck all tough the billet dizzy "looks" nice and is new,not sure how it will stack up though I am waiting on the billet ones from firecore thats gonna be out soon keep us posted if he does go with it

So how well do these work?
They work great. I have one in the 440 in my Coronet. I checked the advance curve and it matches what Mopar Action recommends.

I have a msd pro billet distributor and msd 6al box. What would be the best setting for the distributor? Right now it is set at 2 heavy silver springs and silver bushing per the instructions. It starts to advance at 1400 and goes to 5500rpm then levels off. What would you suggest. 440ci, 0.040" overbore, 0.474" purple shaft cam, Hedman headers and 3.23 gears. Just street driven. Thanks for your help.
Bob, assuming sufficient octane vs. C.R., you need a curve something close to this:
Under 1400RPM - no advance - set initial at 15 degrees BTDC 2000 - 10 dergees mech (25 total) 2500 - 20 degrees mech (35 total) - all in.
Plus, at LEAST 15 degrees of vacuum advance under light throttle (50 deg. total, 52-55 better).
If it currently doesn't go to full advance until 5500, you're giving up lots of power.
If it currently has less (or no) vacuum advance), you're giving up LOTS of fuel economy and fouling plugs.

what kinda price they going for???
My dad has his eyes on one for 255 thats another reason why i told him to use a stock points dizzy for it and he can buy some other stuff with the money he would save, but he is on his whole shiny deal (must be getting old) Guess they will match his polished MP valve covers and air cleaner
