The engine is in the car. Is it possible to do that without removing the motor?

Yes, it is in an earlier post.

From the mopar b-rb book the cam is at the upper limit of the tolerance on 3,4,5 and over by .0005 on 1 and 2. I got this from a youtube video who got it from the mopar book.

Just curious, does anyone have a known good cam for big block sitting around that they can measure the cam journals? Without a very unique bore gauge I can't see getting an accurate measurement of the bearing diameters. I did run a borescope to look at the bearings but saw no dents or burrs.

No the cam bearings were not replaced. The cam is straight. Within .0005 inch. Fwiw, it tried the cam in backward to test the first journal. Very snug fit. Could barely turn by hand with lube on it. The original cam turned nicely but was not sloppy. No signs of wear on the cam at all.

Dwayne is arranging a fix for it. I have until spring to get this back together, so no hurry. My machining days are behind me. No more machines to use.

From another site I found the bearing sizes. here is a compare of what I have bearing size ---------- new cam -------- old cam 1 2.00-2.001 ---------- 1.9995 ------ 1.9975 2. 1.984-1.985--------- 1.9835. ------- 1.980 3.1.969-1.970. --------...

Comp cams

Well, I thought I had everything ready to begin the install. Then I went to install the cam and it would not fit into the existing cam bearings. I inspected the bearings with a bore scope and then tried in the old cam and it fit easily so no burrs or dings prevent install. Then I measured the...

Correct, I had to go back and read my thread on degreeing my cam.

Retarded 8 degrees

Just 3 runs. I was mostly just curious where we were. We had not even been down the track yet.

He offered to do that but I was not ready to do any tuning. It was more of an assessment. Next time we will do tuning at the dyno.

Does that help?

I am not sure at all what the timing or fuel were at with that plug. I will be getting new plugs when all is ready to go with the new cam. Since it is so easy to change the tune during a dyno test, what changes would you like to see for that test. I will make a few tunes to prep for that.
