Hey, how's it going been a long while, so time for the fun.....

What advance do I run on a 400 on propane? Any one who has more experience with this then I please let me know, the whole propane system was cheaper then a new 4barrel and came with a full tank off a running truck

Thanks

I don't have a 400 on propane, but on my propane fueled Mopars (6 and V 8) I run a heap more initial, but less total. The 6 is something like 14 initial, with 30 total.
What works for one is not necessarily what will work for another, but that will be a starting point.
