440 cam button

[moparquest]

Hey, guys. I wonder if I could get some advice as to what cam button to order for my 440 build. I've installed a Lunati roller cam. I'm going to run a double roller chain. I see a few choices out there (nylon, aluminum, roller type, etc.) regarding cam button spacers. I'm planning on a stock timing chain cover. I left the plug out of the back of the block so i can measure the endplay on the cam with a dial indicator. Does anyone out there have a cam button spacer that's been trouble free (i.e., no "oil canning")? If so, would you mind sharing the details of what P/N and installation technique you used? Thanks in advance for your input.

i prefer the nylons and dislike the rollers. nylon or delron have very good wear characteristics, but need to be fitted. most people reinforce the sheet metal cover.

So, when you say fitted are you saying dimple out the timing chain cover? Or shave the button? I assume you'd install the button on the end of the cam, put on the timing chain cover, make sure the distributor gear is installed and see how far you can get the cam to thrust toward the front of the block? Thanks.

I agree and use the nylon.I use a Milodon gear drive so my cover won't flex but the stock cover will tend to flex.I have seen some nice aftermarket covers if it's in the budget,if not reinforce the stocker and cover it with paint.:blob1::blob1:

i just trim the button to fit using some sandpaper on a firm surface. of course the timing cover and cam gear need to be attached. its a little trail and error but the nylon will last forever and seems to have a good compatability with the sheet metal cover. one thing i don't like about the ones with the torrington bearing is the metal on metal wear. besides that they fall apart.
