New life for an old 340 (stock stroke)

Guess I better get this on the dyno in order to un-hijack the thread. I leaned on a buddy and scrounged an oil filter plate and stub (I hate calling it a nipple). These parts are $40 each at the dealership here. It's currently full of oil and pushrods are cut to length and made-which I may have gotten ahead of myself. I made ball-cup pushrods using a 273 set of adjustable rockers to check length-but am now considering the PRW-PQX stainless roller rockers which require ball-ball pushrods. Still I think the roller tip is a pro that outweighs the cons. Will have the rockers/pushrods next week. J.Rob
