It's been a couple of years but I found a Mopar performance double roller set for a /6 on eBay.
I also bought the last double roller set that rock auto had around that time. Had to buy as 3 seperate components all the same brand as each other, they were some of their "wholesale closeouts". I believe that as seperate components the chain itself fits many actually. Big block Mopar of course but I believe also big block shivvy too.

Degreeing the cam on this 83 slant six. It is a hydraulic cam and I'm not sure at how much lift I should read the BTDC measurement. I don't see a lobe center degree value. I'm getting 7 degrees BTDC at .02 measured on the lifter. If I measure at .05 x 1.5 for theoretical valve lift I get 2 degrees BTDC. Intake lobe center is 112 degrees. Attached is the OC cam card. Looks like the theoretical valve lift is close (1 degree measures 2 card says 3 degrees)

Is my last measurement correct? Should I advance this 2 degrees?


ETA
Measured at .05 and it is 5 degrees ATDC
So 8 degrees advanced?

Picture of setup.

Your intake centerline on the card says 104. I'd drop a solid lifter in it and use it for degreeing.

Check it at whatever lift you want before and after TDC. Use .020, .050, it doesn't matter. The center of those two readings give you actual centerline.

Thanks!

Intake lobe center line is 112 so retard 8 degrees.

Yes that should be correct.

If anyone needs the factory red for their engine, I had PPG mix me up and create a formula in there Shopline paint that is a dead ringer for Mopar Performance Red. You can go to your local PPG supplier and have it mixed.
I'm getting ready to paint my block here shortly, I'll post some photos and the formula after I get painted. I had the Mopar Performance turquoise matched up also, they both are right on and look great once painted.
