1978 Corvette L82 oil question

Hi,

Can anyone tell me what oil a 1978 Corvette L82 calls for? I have this engine in my 1969 Camaro but I have no idea what oil to put it in it.

Thanks!

10/40 or 10/30 should be fine.

Yup. Factory called for 10-30 in most climates. 5-30 wouldn't be required until something like alaskan winters, and 10-40 would be good for an older engine where the bearing tolerances might be a little loose.

Zinc based anti scuff anti wear additives have recently been removed for the typical recomended engine oils made for automotive use.
These Zinc anti wear additives are nessessry for long flat tappet cam+ lifter life.
Either use a oil rated for HD diesel engines (most still have the zinc additive {for now}) and or add GM "EOS" relabled as "GM assembly lube" or other Zinc based engine oil additive to your oil.
The lack of Zinc based anti wear additive in modern recent reformulated engine oils will shorten the service life of engines with flat tappet cams.

Shell Rotella T 15w-40 works well. (for now) many "racing oils" "for off road use" still have the important Zinc anti wear additives.

Moly is not a direct replacement. Its anti wear qualitys serve a different purpose in an engine. (initial Cam and piston ring break in)
PTFE resins (Teflon) {or any other miracle additive advertised on late night TV} is not a effective replacement. Why would some one want Teflon in there oil filter? Why, oh why would some one dump sand in their motor?
Does this test sand have a SAE specification?

LOL! Even DuPont (makers of TeflonŽ) don't recommend it as an oil or oil additive component.

Seems that it plugs up oil rings, too........

There are still some oils made with the SL service rating, which means there's still ~1000ppm of ZDDP in them. This may be enough for an old stock engine with a lazy cam profile, but it might be a bit light for anything more modern.

The ones I've seen were 30w or 10w40, and were mostly house brands, not major brands. Same source oils that were either 10w30 or 5w30 seemed to all have the low-ZDDP SM rating.

I'd use some kind of SL oil, and I suspect a can of some kind of high-ZDDP racing oil or EOS added to the mix might be an idea worth looking into, especially if you're running anything that's non-factory.
