273, could it be a commando and CAM question?

Alright. So today I stopped by the garage and did a compression test. The picture reads 140 psi but the needle dropped before I got my camera up it was actually closer to 150 psi. The tool was one of those where you press a rubber nosle into the plughole and I really dont know how accurate it is. Also I was in a hurry!

Anyway, do we have reason to believe that it actually is a commando now?

Please feel free to chime in on my cam questions above aswell. I found out today that it is a hydralic cam, lifters and rockers, so the cam is aftermarket and probably is a 340 cam. Should I just be happy with it?

Djakken that is awsome, do you have a build thread here? I have some pictures and a little info here, it is not up to date though.

I agree with your comments on 340, I would love one, but the money when they do show up.... Just cant afford it right now. Had a hard time finding the 8 3/4 axle. But now I finally have a 3.55 sure grip and I'm very happy. Had 2.76 before and stock converter. The change now is dramatic :)
