After much work over the winter and fall on my 76, including removing the 1972 3.08 and installing the original 3.36, rebuilding the Qjet and installing in place of the Holley, I have to say my car is running great. Shout out to Lars for his Qjet and timing papers. Worth their weight in gold.
Forgot to add, I will be replacing valve stem seals in the near future. The engine only has about 39,000 miles, but it is over 50yrs old. And reason to replace the valve springs on the stock L48?

Thx in advance for any insight.
Instead of the stem seals and springs just replace the whole cylinder heads, instead of just the cylinder heads change the cam too, if you’re doing all that you might as well do headers…..
If the springs aren’t causing you any trouble I would leave them alone. Lest you fall down the rabbit hole.

The old style umbrella seals are prone to leak. If thet remove the heads to do the seals, have them machined for Viton seals and refresh the valve seats. Most of the cost is in the head removal so refreshing the heads is cost effective versus removing the heads in a year if a valve fails....I would compare costs of stock head rebuilding to a new set of edelbrock heads with better (smaller) combustion chamber size...it will equate to cheap power and no rabbit holes. Edelbrock rpm headscare cheaper than AFR, Brodix, or other high end heads. Aluminum heads will allow more timing as well....less chance of detonation.
And instaed of a cam change just go with a 1.6 or 1.7 rocker arm...its a cheap upgrade everyone did back in the day when no one had money.
After 4 years, no more "what time is it"
Background music is the garage radio, not the car radio. Ignition is off.
Took me about 1.5 hours, as I bent the second hand during install, and had to disassemble and straighten
out everything.
Getting old sux.
Edit: It's a '76.
Good job Mike, my 76 clock doesn’t work, one of these days I’ll get to it, but not high on my list now. Any suggestions for repair? And yes, getting old sux, my vette is a 76, and I am turning 76 in December. 🤨

Not a repair, but quartz replacement.
Easy part was removing it. I thought about a repair kit, but those pieces are too tiny,
and my nerves just say no. I'm long past the point of keeping this thing all original,
but it still looks like it, mostly. (from this past Wdnesday)
This is a follow up to my earlier post on dropping my '74, L82, 4spd vert at the body shop to get the rear 1980 bumper removed and a new 1974 repro fiberglass bumper installed. Just picked it up, I think it came out nice.

My quartz clock was 11 years old when it started getting fast. There isnt a way to fix it so i put an oroginal back in. They will self regualate after some time adjusting. I didnt realize that until i was researching the stock movement...sometimes a good cleaning and a tiny bit of clock oil will bring them back
