Happy holidays to all on here! Burd, thanks for the battery info...much appreciated!
I thought I would post what I uncovered regarding the timing miss. When I got the car it had a slight miss at idle. I replaced all the usual stuff to try and cure this annoyance...plugs, plug wires, dist cap...and the miss was still there. I now knew it probably had a bad cam, bad lifter, bent pushrod, or bent valve. I learned while picking the car up from the original owner's husband, Lyle, that the mechanic who got the car running (Sonny) had towed the car behind a pickup truck using a long cable to get the car running by popping the clutch (note...never use a mechanic named Sonny from Arkansas while trying to get a classic Camaro that's been sitting 39 years running again). I also learned that he didn't remove the distributor to pump up the engine's oil pressure (DOH!). I knew that the engine's internals had probably gotten pretty hot during the traumatic restart and had possibly wiped out something internally. The pushrods were arrow straight and the lifters looked good with the exception of the number 4 exhaust. I removed the radiator, grill, front bumper and valance panel to access the front of the engine. The right side engine mount bolt had to be removed so the engine could be raised enough on that side to remove the 32" long cam with a 6" diameter timing gear attached.
The number 4 exhaust lobe showed a lot of wear at the top of the lobe...it had obviously taken some serious heat (it's very visible in the first photo).
The timing gear was the original factory nylon gear and looked in beautiful condition (remember, this is a 45k original mile engine). The Chilton's manual said that both the cam and crank gears should be replaced, but replacing the crank gear would have meant pulling the engine (no freaking way, Jose!). My alternative was to either reuse the original gear or replace it with an NOS gear (I found one on Fleabay, along with an NOS cam...the cam was only $60...no one except freaks want six-banger stuff).
The new cam was installed with plenty of red Permatex engine assembly lube (Burd says to always use a lot of lubrication when inserting things into holes, but I never know if he's referring to engines

). The new Sealed Power lifters were soaked in motor oil for several hours to work out any air bubbles. I had a nice set of sidecovers from a '69 Nova six-banger I had a few years ago and installed them with Felpro cork gaskets to brighten up the engine a little for the next Cars n' Coffee at Burd's.
The job is now mostly done and ready for start-up and cam break-in...I'll keep you guys posted.
