Milodon has been making a "stock " looking TC cover for several years now. 50 bucks and they are much heavier gauge metal than stock. I use them all the time. Todd

What are you using for the timing mark indicator?

Would this be any heavier duty than the stock piece?

yes they are heavier. They also sell a pointer for like 7 bucks. They also have the front seal but no gasket.

You talking about the Mildon or the Proform?

Just me, but if I cannot afford one of the AREngineering timing covers I cannot afford to run a roller cam.

Maybe I'm wrong or crazy, but the stock cover has worked for me. I thought the cam driving the oil pump puts rearward thrust on the cam? I don't know what would make the cam thrust forward (or how hard?), maybe if the oil pump was spinning faster than the cam?

Does that have a torrington bearing on the back side of the cam sprocket ??

My apologies I was strictly speaking on the Milodon unit. No info on the Proform. Todd

You are correct. Look at the photo below. A cam rotating clockwise will drive a) the gear down and b) the cam rearward. The button is more of a precaution.

Don't think it's a problem being it's been many, many years street/strip and after the last freshon up 11 years ago, it still looked and worked great. LOTS of wives tales out there.....

I put a lot of Indy covers on,starting way back in the very early 90's.First with fluid dampers and then with Innovators dampers.I just spaced the water pump out 3/4" for fluid dampers and 1" for Innovators and made my own cam buttons.I set them all at .003-.004.

iagree My 575" hemi and my wedge both have solid rollers and stock timing covers. No issues.

On the distributor collar issue...if the gear moving up and down won't affect timing, then why does the timing get much steadier after installing the collar? Is something else going on here? I've done this on both of my own engines and the timing most definitely does not move around nearly much w/ the collar on the distributor from my experience.

Does it "really" get steadier or does it just seem that way 'cause you've just spend an hour messing with the distributor?

Honestly can't answer your question but the facts speak for themselves, the way those gears are cut there's no way that drive gear should rise up under any sort of load. If the cam moves fore or aft then, yes, timing will vary. But not because the drive is moving up or down but because its being rotated slightly from the cam movement.

Those collars were first implemented and marketed (to the best of my knowledge) by Ed Hamburger. Ed was a smallblock guy and I think a lot of guys jumped on those collars thinking they'd help on big blocks. Unless I'm mistaken, on a smallblock the cam rotation WILL drive the oil pump drive upwards and affect timing, hence the collar.

LOL, could be. laugh2 I could swear the timing got steadier after installing the collar. I remember being skeptical about it, but then being like...hey, that did work. It's been many years ago though. shruggy

Beat me too it, it ain’t a CHEVY guys! Waste of time, why do you think they put the torrington bearing behind the gear?

Small blocks drive them into the bushing also....As I've said before when the engine is running you couldn't move that gear if you tried.

I agree - I really like the one I got from you on my 505 with the roller cam and I have one on my 574 race motor now too.

Went with a Milodon. Ordered a timing pointer also, as the description said there wasn't one included. Cover shows up before the pointer, and there one in the package! Now I have an extra pointer.
