De-stinking Penelope

Yes its got some tiny knicks but really theres nothing there thats goona bite his "end" If he feels he needs another it will be in the box with the other pqrts when i send it..

Chuck, I don't think those gears are going to be an issue, but it's nice to know you've got my back just in case it might be.

Personally I would get another engine from Chuck. I would hate to put that much time and effort into my bike only to have that engine bite me in the end...

The engine won't "bite you" if you go though it piece by piece and measure/verify everything. It's a bigger risk buying an unknown engine and tossing it in.

WAY cheaper and cost efficient to get the packages together with just whats really needed in my opinion.

I 'might' have an issue with third gear so I've thrown out a call to the masses to ask for some opinions. http://www.thegsresources.com/_forum...d.php?t=192113

I'm sure of that. Just think of the millions you're gonna make remanufactuing gauge clusters. Lol...

Had my first request to rehab a set for someone this afternoon!

How many millions are there in doing them for just shipping costs?

I can't tell ya how many early 80's 305's I have come across with a flat cam lobe. Usually an intake lobe.

I've done quite a few myself over the years.

Never knew that about the cases being machine matched I always thought they made X thousand lowers and uppers and what ever one was grabbed from the lines were married..Hmm. Is this due to nesting issues with the bearings??? Seems a very slow process to mill one set at a time custom..

This is close to my corner of the world.

It might be slow, but it's often the only way to achieve sufficiently tight tolerances between mating parts. Anyhow, back in they day, the cases would have each gone through a couple machines before they were done. NC machines weren't very common yet, so a lot of setups on simple machines was more common for a part's process than fewer setups on more flexible machines. Besides, once you have a worker marry the parts up (in a jig it's probably a 30 second job or less), the two parts would finish at the same time. On the whole, it probably wasn't such a burden. In fact it might have been easier, because whole bores are easier to cut than half bores.

Thanks spyder! My wallet thinks it's quite the project also.

Andre, I might tend to agree with you... if I was in my thirties still!

I'd really like to ride it while I still can

Even if it takes you 5 or 10 years to complete, so what! As long as you enjoy fiddling with it.

Dale,
That is one even I can understand!
Dale, just take your time, its not your only ride! The rebuild is usually a most enjoyable time anyway, so stretch it out if you can.

I don't know if you could find out what it was from the factory. What you could find out is what the cam manufacturers of today use for hardness and compare that to what you have.

The reason I suspect improper heat treatment of both cams, is because the camshaft bearing journals look good, indicating proper oiling, a small bit of metal transfer to one of the shims and both camshafts appear to being close to the limit.

Let's not forget the small block Chevy camshafts of the same era, which were prone to having soft lobes as well.

[chuck hahn]

How would you find out what the factory Rockwell standard was???

Or, the camshaft was just plain too soft from the factory.
