How much do you think that it cost to build a engine that's pretty much 100% stock? I'm not trying to argue with you about it. Remember, they have to be as they left the factory except for the pistons. No roller rockers, no headers, no light weight rod's, or crankshaft. Research it out as I have, heck even the carburetor and the ignition has to be factory as does the air cleaner housing. Now you still think that I don't know what I'm talking about? I respect your education and experience and I would appreciate a little support instead of all of the negativity
