Title says it. For those of us that cant afford fuel injection or engine setup will not work for Propane conversion. I have a BBC 468. Right now it has a crappy Holley that some old hack sold me that came off an old mustang or something and he shaved off the choke and all that stuff so it looks like a race carb. Anyways its a 500 hp engine has a decent cam with nice loap. the existing carb sucks offroad engine stalls over 2-3 ft whoops going slow or fast. Lets bring the ideas and let me know why. Keep in mind it's a big block so I'll need cfm's above 750.
