Recipe for 351M engine upgrade

Anyone have a good cam/piston combo for rebuilding a 351M for a performance upgrade. Looking for improvements over stock and I am running a dual fuel gas/propane setup and will probably go to a strictly propane setup as it is over $1.00 a gallon cheaper than gas where I live and it is legal on street vehicles in my state. Like to keep the costs down as it is more of a toy and I am on a tight budget. Thinking of piston, cam, intake upgrade and using stock crank and rods.
Thanks,

If you're thinking of different pistons, then in addition you might go ahead and get a 400 crank and pistons and make it a 400. The best place to get answers would be to post the question in the 335 series engine forum.

Propane may cost less than gasoline, but it is hardly a performance fuel. One gallon of propane contains less energy than a gallon of gasoline (82,485 British thermal units [Btu] for propane, versus 115,400 Btu for gasoline. That's a big difference if your goal is to increase performance.
