A True Low Dollar Backyard Build

So I got a hold of the guy that use to own the cam, rockers and heads. As he recalls from a couple of decades ago, the cam is a hydraulic piece. Says the rockers he saved from a 273 he had in a dart many years prior to his 340/360 days.

So is it worth running the adjustable rockers with the hydraulic lifters, or just stick with the stamped steel rockers?
He does not remember if the J heads ever had any work done to them. For now we'll assume not. It'll be a while before I get around to dragging them out to look closer at them.
