Thread: Cam buttons and timing covers

Tweet

less then your posted numbers . you do not need much end play with roller button and roller thrust washer . (bronze washer) i like if going on the street and a solid button can wear in some. but I think the solid button and bronze washer can take can take more of a back and forth. EZ to fit the solid button with not many tools .i like just a stock tin front cover .i set them with not much end play . there is some oiling things i do as well . and some other things that i do not care to talk about have to keep some thing s to my self . JERRY may chime in to get away from all this stuff is to use the mark 6 cam. the cam is cut for a plate that will bolt to all the gm mark 4 blocks some of the early 396/427 and the tall decks may not have the holes in the front drilled and tap but not hard to drill and tap i done it . you end up with a mark 6 cam . cam plate. chain set. and no buttons
