you know, i dont know too much about the engine, its a 454 bored to a 468, and im not sure about the cfm of the carb or how to check. i just pulled off the valve covers, and i dont know if its supposed to be like this or not, but some of the rocker arms are pretty loose, and some are really tight, i dont know if its because of the way the cam is sitting or what. as you can probably tell, i dont really know a whole lot about this stuff, im kind of learning as i go here. thanks a lot for all of your help
