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?

yes they are heavier. They also sell a pointer for like 7 bucks. They also have the front seal but no gasket. Todd You talking about the Mildon or the Proform?

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?

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.....

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..... 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.

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.

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.

The button is more of a precaution. 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.
