Ignition timing on propane small block

Thanks jake,what engine have you got / cam etc.
I am thinking of trying a locked distributor at say 25 degrees to start with to see how it likes that. The current distributor has about 24 degrees advance so i cant run much initial timing and it feels very soft off the line.
No problem! I wouldnt like to get that much advance, maybe try welding it smaller? I tried mine higher and that curve fell off a cliff at around 4300. Ive got a .40 over 273 10.5/1 with a compcams hydraulic .454/.454 with 3.23 and a stock converter. Im going to over haul it with my magnum goes in next month and try a good mechanical/solid cam.
