I'm in the process of building a '69 302. There are a few parts I am having trouble finding, one is the '69 Z/28 solid lift PN 3927140 camshaft and lifters. I can get aftermarket all day long. I'm looking for the ORIGINAL parts. Anyone know where I might find such parts?

Is it really that important? To have an exact obsolete cam? Where no one would ever look unless the engine is completely torn down?
There is this:

Too bad you missed out on Smokey Yunick's garage sale in Florida a few decades ago....
Crane makes a blueprint of that cam.

Just throwing this in. Many years ago I bought a 69 chevellle with a blown up 6cyl. I then bought a crashed 75 impala for $50 because it had double hump heads someone had stuck on it. Engine was tired and I thought it had a bad oil pump because all the lifters were clicking plus it would not idle well.
Once I got it degreased,found casting numbers etc I found that it was a 1967 302 chevy! Engine code was "MP"! Upon tearing it apart I found the popup pistons and a 3030 duntove solid cam...no wonder the lifters were so noisey! I reringed it,replaced the cam with a hydraulic cam and had the heads rebuilt. I was using the 75 impala 2bbl carb on it in the chevelle with 3.08 gears and a 3 on the tree it ran 14.47 @ 3000ft!
The 30/30 cam was used in both the 302 and in the 70 LT-1 so you may have some luck at Corvette parts shops. Steve at Steve's Camaros in San Bruno, CA had some NOS cams and I believe he had a 30/30. This was probably ten plus years ago. I don't know his current inventory but he may be worth a shot.
Good luck
Put a Comp Cams Thumper cam in it.

Back in the early 60's my dad had a '63 & '64 Pontiac Catalina. He raced the '63 and would always have spare parts on hand. Of course I wasn't born yet, but my uncles and my grandfather told me all about it later in life. Anyway, December '63, he bought a spare engine for his '63 Catalina. The Catalina came factory with a tri-power SD 421, 4 speed, and a posi rear end, but I don't remember the ratio. The spare SD 421 came from the factory complete from the tri-power intake to the oil pan. But, in 1983 we found out it WASN'T a 421. Pontiac made a handful of .030 bored 421 blocks that were actually 427 ci. This is a VERY RARE engine. Almost as rare as hen's teeth. And, my dad STILL has that engine, covered, on a 4 point engine support sitting next to the factory crate it was delivered in. About every 3-4 months he has someone remove the hand tightened only factory spark plugs and shoot a few shots of RedLine 30wt. racing oil in each cylinder and rotate the crank a few times. The pan is also filled with RedLine 30 wt. racing oil.
My dad had this conditioned warehouse built in 2002 when he finally retired and sold his heavy equipment and dirt service company. This is where my hoard of goodies are stashed. My dad keeps his '65 GTO, 389, 3 deuces, 4 speed, car parked there. He also has a '57 Plymouth, a '56 Buick Special, and his most recent find, a '69 SS El Camino, 396, Turbo 400, posi. This one was a basket case, but it's coming along.

great stories + info!!! prolly a lot of GOODIES stashes in many garages + sadly many are prolly rotting away!!! but as much as i love nostalgia todays modern hi-tech engines excell + easily make big power reliably due to excellent designs. watched a U-tube today where Nelson aka Nelson Racing talking about the superiority of LS + LX engine designs, but of course they are costly unless your lucky again + get one from a wreck or whatever!!
