273 Commando Intake Rpm Range

I think my 71 Demon had a 2bbl single plain on it just like the early 273s. That thing went 5500 until the valves floated.

So Ima thinking the Commando will go as far as you put cam in it for,lol. What it does on the way there, I cannot say...... But hey you already own it so if you put reusable gaskets on it, it won't cost you a thing to try it. My FelPros are on the third cycle at least. Yeah I know, I'm such a tightwad; but if you never try something, you'll never find out. If you can figure out how to make babies, you can pretty much figure anything out...
