This is a Cloyes 3028X timing chain set that will allow me to retard my cam by 4°. I just need to be sure that I am retarding it instead of advancing it. No damn instructions came with it. It is being installed on a 360.
Which do I use? It looks like the rectangle spot to me. Any thoughts?

Your title says you want to advance it- your thread you mention retarding it. Which way are you going?
And for sure degree it as mentioned above. It's the only way you'll know for sure what you've got.
 
Why would you want to retard a cam? That almost never works out well.

Unless you know it's installed way ahead of where you want it. NEVER, EVER trust the marks to do what you want. Always verify.
 
I just installed a cam that was reground. When i pulled it out it was dot to dot and measured 1* advanced.
I got it back thinking it would have no advance ground in. So i used the 6* advanced keyways and it was way off.

Ended up using the zero keyways and installed at 105*, 6* advanced.

Gotta measure to be sure.

THIS!! Most of the time you want to crank them ahead. Retarding a cam starts to kill bottom/ mid range and raises the HP peak
 
I've checked with a wheel years ago that was 11 degrees retarded lined up dot to dot. Jes sayin. Just because the crank sprocket "says" it's in a certain location doesn't make it so.
 
Honestly, I am just experimenting. It was a running combination and I am just curious about what effect it will have. My hope is to soften the bottom end and raise the top RPM a couple hundred. If it doesn't workout I'll put it back. And then I'll know.
I have tons of 1st gear gear gearing. 28" tire, 2.70 1st gear in the trans and a 4.30 gear in the rear and a 3500 converter.

I don't consider 2.70 a "ton" of first gear, but ok. It could be a 3.09. lol
 
As far as Mopar auto transmissions go, I think that is as low as it gets for stock offerings. And that coupled with the 4.30, it's pretty low considering.

Yeah,,,,1st gear in the 904 was a 2.74 for the wide ratio low gear .
4 speed stick was 3.09 in the overdrive model ,,,,but Rusty knows all this .
He’s pretty sharp on this stuff.

There is a non OD 3.09 first gear transmission.

That’s what I have.

And a 4.88 gear. And my overall first gear is still too tall.
 
As far as I know the non-OD slant six and the 273 4 speeds had the 3.x low gear
 
@Clelan
Yeah well with a 3500 stall, you never use the bottom end anyway. I'd have no problems giving it away. I'll grab a couple of hundred on the top any day with that 4.30 gear.
Even did it on a 2800, and it worked just fine.
Even did it on a 292/292/108 cam, with 11.3Scr. But that cam was just too big for my application, period. It wasn't in there very long. My current 276/286/110cam was installed straight up, and I left it there. I also still have way more bottom end than the chassis can deal with.

Way more bottom end than the chassis can deal with ? Nonsense . You just don't have the proper tires.
 
**** sake, it's an experiment. When the converter flashes to 3000 plus, the bit of effect on the bottom end should be a non issue. Maybe the extra couple hundred RPM at the top end will be a benefit, maybe it won't, but at least I'll know. And for the cost of a couple gaskets and a splash of RTV, It's a cheap experiment. I am not arguing that it will or won't benefit me, and I never said I wanted to soften the hit. I'm just trying something.

I can tell you from my experience, it's not a good approach.

The expected gain up top is not likely going to be there, other than take away from the usable range.

Refining the tune up will garner bigger gains, JMO
