The cost of rods, pistons and cams, between OEM, and aftermarket is minimal, and I am a budget, should say old budget minded racer, so I'm sure a guy who still works, can read an assembly book, could build one, quit smoking, and partying, you can do it. I might add, Crane and Crower as well as others sell cams within a few bucks of new stock ones, H- beam rods are as cheap as stock ones that have been reconned, and good popup pistons won't add anything other than longer life, and more compression, which makes that alky burn faster. The motor Im building is a 2.0 Mitsubishi, same as a Mopar 420a, really common, and cheap. Bob
