No kidding. I wouldnt even consider driving it in freezing weather
That is a not car that you can just go out and buy another.I'm surprised so many are cautious about cold driving. Won't see any inclement weather.

I run the 0w40 euro oils in my old V8 and everything else I own. No issues.a Euro 0-40 or even a high ZDDP 5-30 like RP HPS
You don't have cats to worry about (not that it should be a worry) so you can run anything you want really
Thanks Ken. Agree, I wouldn't drive it on anything but clean roads. I'd say 4.11s because on the test drive I was turning 2000 rpms in 4th around 37mph. The old owner was a dirt track racer and liked to go fast. The sun pro tach had the redline set over 7000 rpms. Now, I don't hear any kind of cam like that in it but aside from one test drive where the brakes failed, I haven't driven it.Well that is the nicest car I've seen on here in a bit. Or at least one I like the most being a GM guy
The best years for american Iron 65-66.
You can decode the rear end, it has stamping on the axle tube
If it's CI or CU its probably the 3.73 posi if you have the close ratio transmission.
May be CG 3.36 posi also. Stamping is on on the axle housing about a foot from the drum brakes
For winter I would just run you choice of 10W30 with some Lunati break in lube or similar
Just keep it under 4500 RL in the winter.
I guess a lot of people don't know the roads can be clear and clean many days during the winter.
Better to run the beast than have it sit, for sure.
See if you can find the broadcast sheet under the rear seat - it will have your RPO's listed.
Look a bit under rear carpet too
Have fun and - request more photos or a youtube video!

WOW. Hard as it would be, that car would not exit my garage unless under bright blue sunny skies!!!The Chevelle is a L79 car, the high 350 horsepower 327. It has a healthy hydraulic cam, not sure if it's stock. Previous owner ran Mobil Delvac 15w40.
I'm looking for oil that's more cold start friendly. I just bought it and I'm expecting alot of cold starts in the next few months.
I don't know any specifics about the engine. I believe it has been rebuilt, atleast I expect the heads were since they look new inside the valve cover. The owner died unexpectedly and all useful knowledge went with him, he'd owned the car for almost 50 years. This SS has a 4 speed and 12 bolt with I'm guessing 4.11 gears. It will be turning some RPMs and wants to rev.
Here's a picture from earlier. Replaced the master cylinder and all the wheel cylinders tonight. (Master and couple wheel cylinders were leaking)
This is what I’m currently running in my Buick’s 455 (462). I only have about 600 miles on it. I only drive it maybe twice a month on nice sunny days. I know these older motors want a high Zinc oil that’s for sure.Valvoline Vr1 10w30 full synthetic.
