I'm not for sure of the condition of the 4200. It was a longblock swap at a Chevy dealer in an 09 Envoy. The mechanic claims it has a rod knocking, I won't know until I dig into it. I have very little money into it right now. I sold an oil pan and valve cover from a 235 to pay for it.
I wish it had more of the accessories with it, but I can at least do a mock up with it.
I should've weighed it while it was in the back of the truck. Hind sight is 20/20.
I do know it is top heavy, I guess the twin cams and 24 valves have a little to do with it. I have it sitting on the floor, chained to the workbench right now so it doesn't fall over.
I know there's a long road to go with it, but if I can get all the excess 235 stuff that I have gone, I'll at least have some extra $$ to work with.
