Yep. Mopar small blocks are hard on chains( chains are long). You have to use the tensioner with them, and i dont really like the tensioner, but have one on my current build with a cloyes.
But that milidon gear drive is sweet

So the gear drive is that quiet? I guess I haven't heard the small block ones, or seen them. The b.block ones are way loud.

The Milodon is a single idler type not to e on fused with noisy floating dual idler gear drives.

Milodon.

It's called a gear drive.

Wouldn't mention it because you asked about a timing chain, but the Milodon GD is bullet proof, you'll never have to buy another one and, your cam timing will be the same on the engine stand, on the first fire up, and 100k miles later.

Oh yeah, baby. Wish I had one! Came real close....
 
In fairness, I should be totally honest.

I had a phone call last nite from a buddy who reminded me about a Mildon GD he installed that made noise, AFTER I promised him it wouldn't.

Here is the poop.

I did the machine work, he did the assembly, of which he is more than capable. When he installed the GD, the mounting bracket that holds the idler gear comes down and and too the drivers side.

I've never seen it, but there is always a strange on out there.

On his particular install, the very tip of the idler bracket was touching the timing cover. And it DID make some noise. Fortunately, I've heard noise gear drives before, so I knew something was off.

He drove over and we pulled the front off the engine. It took me a bit to see the witness marks. Did a little massaging and it was quiet as a church mouse.

So...be careful when doing the install. You can have the mounting plate touch the timing cover and it will make noise. Make sure you have clearance and you are good to go.

Other than that, you should never hear it.

You'll be ok with the line bore. There is enough adjustment when you do the original install. I forgot all about the one touching the timing cover. It was a head scratcher for sure. Glad my buddy reminded me of it. It was just the perfect storm.

BTW, that was 1995. He has had probably 7-8 engines done. Same gear drive. It has saved him hundreds of dollars over the years.

He, like you had apprehensions. Now, he won't use anything else.

holy **** Batman that's a long time! Well if it works out, I have two other motors that will get them!
 
I'm on 16 years with my Milodon in my streeter 372. Agree with yellow rose 100%. Timing is still rock steady. I run full exhaust and the car is not super loud, you'd be hard pressed to hear the GD. Plenty of adjustment for the line bore also. The install was really straight forward and not difficult.

alot really cool guys on this site! Thanks for all the input. I run a belt drive on my big block doesn't make any noise! Lol ! Unless it breaks!
 
Was speaking to my engine builder about gear drives. The only brand he said he would rate is the Shaver Wesmar, I cant see them listed for a Mopar.

For those that have the Milodon item, how much power are you making?
What actually kills gear drives?

Milodon gear drive is installed on a car i used to own. It makes right around 700 horse. Stroker smallblock. Its been 140 at 3220 pounds on 002/003 leafs.
Gear drive was installed 8 years ago or so.
There is zero downside.

My 345 inch small block made 695 at 8100. That was on fully ported (square) W-2's, a Holley Por Dominator with 2 flying toilets on alcohol.

IIRC, that engine had ~310-315 on the seat and again IIRC ~750 over the nose.

That same gear drive went on the next engine with more CR, W-5's with a MP TR and the 2 flying toilets on alcohol. That made 725 at 8100 as I took some at .050 out of that one to keep it from going to 9000 because the W-5's made much more air than the W-2's. That engine had 350 on the seat and almost 900 over the nose.

I purchased that gear drive in 1986. It is now in my 425 HP daily driver. I've never had to replace any part of, not even the idler gear bearing. The only thing replaced was the thrust bearing hat goes behind the cam gear. I ate up some lifters and lobes and crap went through the bearing and screwed it up.

Other than that, never been touched.

I just recently put the Milodon gear drive on my new build. Recently I contacted Milodon to see if they recommended any oiling mods.
I was told to check the oil slinger clearance to the timing cover as the crank gear is made slightly thicker than a chain sprocket. If the slinger were to rub on the cover the noise could be mistaken for gear noise. Also in my particular install with a Scat 4.00 forged stroker crank I had to machine the Milodon crank gear inside chamfer much bigger so the gear would press on the snout and sit flush against the bearing journal. For some reason the chamfers are not very generous from Milodon. I matched the chamfer size to my previous Edelbrock chain sprocket that had this large chamfer for radius cranks.
Also Shady Dell speed shop told me to Dremel a small groove on the back side of the mounting plate to channel oil to the area where the cam rubs against the plate. (The opposite side of the roller bearing).
I also was told to drill a small .025 hole in the front oil galley plug to get oil to this groove and drill and tap the hole in the mounting plate in front of it so it does not just leak out of the plate.
Finally Milodon reminded me that you still must put plugs in your front oil galleys under the plate and not rely on the plate to seal them or you will have no oil pressure.

All true. I leave the slinger off.

I also forgot to mention when setting cam end play that if you have too much you just machine down the cam hub by the amount you need to take up...i.e. if you need to close up the end okay by .010 you take .010 off the hub.

I suspect Milodon makes them long so you can set the end play.

Interesting about the end play. That could be tied to why shady dell told me about the oiling mod. He said he has seen the back of the plates chewed up pretty good. He figures lack of oil but could be not enough end play. Is there a spec for the end play. I did not measure that.

What part number was that "best " Cloyes chain?
 
Using the milidon gear drive do you use the factory oil slinger on the crankshaft? As I am finally installing the gear drive!

Demon 550 I made a post about the slinger and a few things to watch out for during the install just a few posts back.
 
Yesterdays install.

Not quite a small block, but the same part #. In this case the oil galleries definitely need the cup plugs added.
