Default Cam repair

For those of you that were waiting for me to get the "salvage worn journal model A cams" project going, it is going and works good.
The lobe regrind part will be a grind that is very similar to the stock original grind EXCEPT that it will be modern design and run on one inch lifters. It will also have a larger nose radius so it doesn't wear off like the original grind.
I will have a sample of the journal repair for viewing at my shop during the Puyallup meet time. I am 45 minutes by model A from the fair grounds on the road to Mt. Rainier.

Pete, does this basically give a little less lift but more duration?

Good cores are getting scarce enough that it should be about time to do.
It will be CONSIDERABLIY cheaper than a new cam.

Sorry, no time to do that and no camera either.
Take a look at a new stock cam and these will be so close you will have trouble telling them apart.

Pete, what does the journal repair involve? Is it spray welded and turned back to standard or some kind of sleeve?

Sleeving sounds like a good idea . You could probably also sleeve them oversize to take up slack in a worn block as most have.

That could be done. However, most of the time the wear in the block is either not concentric or it is egg shaped.

I have sleeved many cams where the block was bored to take an oversize off the shelf insert bearing. These cams had .480 lift and radius lifters.

The thread is about both journal repair and lobe regrind.

The factory did some repairs by hardchroming, I have a cam that the #3 bearing surface is hardchromed, and have seen another with #3, and one with #2 hardchromed

Yes, it was quite common in the old days but you can thank the EPA for running the price of hard chroming up now to where many other ways are cheaper.
