there were write ups on how to do it back in the day
We built a 413 with longrams for a roadster pickup
471 on each long ram

BTW how about EFI for those longrams? port injection would solve lots of problems
which of mikes grinds did are you getting
Don Bass was the expert at TMS propane, genius, wrote well, I learned a lot from him
