Hay Mike what did your counsel come out of ?
When the engine was cold, it was fine. But when it got hot, you could hear all 16 lifters. Sounded like a solid cam. So when hot, they bled down because of the flat ground on the sides of the lifters that provides oiling to the cam lobes.Wow, ok, how did they fail, not pumping up or not spinning on the cam??
Rollmaster on the timing chain set.Cam is on its way, waiting to sell a couple things to get my lifters and duel roller timing chain, any reference to what chain and gear set to look at I would appreciate it.

It cam out of a 71 Monty Carlo, same as 70 to 72 ChevelsHay Mike what did your counsel come out of ?
Thank you, need all the input I can get by our experienced engine buildersRollmaster on the timing chain set.
And I looked and looked for something thin enough to fit between the seats of these early A bodies, and they are not so pronounced on it being a certain builder co. I bought it with out the center top, paid 40.. should be able to find one.Thanks for responding. I knew it was most likely from GM or AMC , now I just have to find one it looks like a great base for cup holders.
On it today, soaking roller change and lifters as I clean and prep bolts, never fun but easy on the back and neckFresh parts should be all the fire you need Mike.
Get out there, and get er done !!!!!!![]()
thank you Johnny, moving forward againMade in Canada baby!!All installed and degreed in, clocked the dizzy/oil pump gear, no more leaning over today, but I did prep timming chain cover area for new gasket a few minutes ago. Roller chain soaked for 4 days with lifters in break in oil.. will coat the lobes again before intake goes on.
Now on to installing center grill and hood latch I guess this evening. Jump on the cover, water pump and Alternator tomorrow morning when I am fresh.

Yep, I was proud to see that, 69 to 71 340, 318, 273 is what I came up withMade in Canada baby!!

I am having problems loading pictures, I degreed it and matched the cam card, not sure what you are seeing, they are dark with assembly lube on it, I agree, Why Would Anyone put a cam shaft in thats not ground yet .In post #535, first picture, it looks like the cam is not even ground. Why use a cam with a rough surface? Am I seeing things?
How can you tell Rob ? And the cam shaft looks great to me, you ?You need to hold onto those rocker arms. Those are 340 rocker arms. They are thicker and more heavy duty than all the other stamped rockers.
Cause they are THICK.How can you tell Rob ?
You know, I thought they was heavy compared to others, but buddy, it's been a long time since I looked at any besides these . Thank youCause they are THICK.
