Actually weighing out the options,I run propane on my F head right now I use my jeep for trail rides and crawling so the pane works great,but in the never ending search for power always looking for options.From what I gather I need more lift in the cam area to take full use of the propane,Clifford says he can do a regrind on my stock cam by changing the centers but if I can get the same amount of lift by using a L cam which I have then why not.I read here befor someone done it but had issues with the springs why not upgrade the springs as well.It's really only needed on the intake side I think the exhaust is the same between the two.Plus thought about doing some playing around with desk top engine simulation software for the heck of it.
