I need to get a 3 bolt timing chain set for my 470 stroker currently being built. Recommendations would be appreciated.

I'm using a Cloyes Hex-a-just on my B motor roller cam. I have a Milodon gear on the race car. The gear drive is excellent and not noisy. It's a head scratcher dialing the cam sometimes.

Pro Gear or no gear

I agree with Cloyes, I use the cam button also, the steel covers are alway pushed out on teardown. Its been my experience that the BB cams do move forward.

Roller or flat tappet? If roller you need a cam button otherwise there is nothing keeping the cam gear loaded backwards to the block. Flat tappet cams if ground properly load the cam gear to the block.

The last Cloyes timing set (it was a hex-a-just) I bought used a cheap chain that ended up breaking links.

Rollmaster.

Not a mopar product, but I have a 496 BBC in my dually that was built in 1997 and has 20k miles on it.
I had to replace the cam last year due to wiped out lobe.
It has a Cloyes Billet hex-a-just timing set that was still like new with no chain stretch at all. It has Edelbrock RPM heads, with decent spring pressure, so I was shocked that chain had no stretch to it.

I use flat tappets in my RB race motors, I have been told you don't need a button with my cams by a good friend and engine builder of mine. That was until we tore down my 500 for a refresh.

It might have something to do with the rpm,7000 but the covers are pushed out.
Cams have been Lunaty or Comp. I've always thought it was from letting off after the lights.?

I've had very good results with Pro Gear, too. I'm sure somebody else offers a comparable product, but I haven't found a reason to switch.

Pro Gear!
