with all the good things Im rearing about roller cams. Tell me about cam buttons, the spacing the cam has to have,and a good timing cover to use.Ill use full kit from comp cams, cam, springs, lifters,chain,push rods,ect,the kit comes with the button also,cloyes has a nice die cast cover for the 454-- ill have to call them and see if it works with the cam set up,**)
you will have fun with the cast cover. setting the end play with them. if any like the last two die cast covers i will not do other with out adding $120 to the bill to make them covers work .there to shallow and i had two spot face the cover on the mill were the buttton would need some end play . and cut the button down in the lathe . no big deal just eats up time had that cover off 12 times EZ to set the end play
Pat, where do you set the play, around 0.008" to 0.010" ?
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
So this " button" is between the cam gear and and chain cover? it bolts on ? also read that the sheet metal covers can be pushed out by the cam? thats why I looked into the cast cover.
funny that GM copied this Mk 6 deal from 50 year old ford motor---
comp cam has a three part cover part#212 269.00, so I looked around and tennesse speed/ street proformance has same cover same # only 69.90 ?:HMMM: am I missing somthing? the picture is from the tennessee site.
Tennesse probably miss priced that part
This may be the one that stinky referred to in his first post....

I think evey time a read something about roller cams I add another part to the list:rolleyes: so tell me about wear plates for the front of the block. Do I have to mill the back of the cam spocket? Iv seen something called a torrington bearing that would go between the cam and block , is this better?
i used them every way you can think of . for street the solid bronze thrust washer is fine you can buy a timming set this way .you do not need to cut the block for a ware washer less the block is worn in here . i also have used a plane upper top gear with no thrust washers as well all will work .i think i posted about this ? yep #4 post
