I have Valvoline VR1 in my 355 with a big cam and flat tappets. 4 qts of 10w30 and 1 qt of 20w50. I could only find 4 qts of the 10w30 locally. Seems like everyone goes straight to the 20w50 around here in the classics.

I run a 10W-40 with a zinc additive in the 396 BB that is in my 70 Monte. I tried running a 10W-30 in it after the rebuild but the oil pressure was lower than I liked at a hot in gear idle.

Use this:
Red Line Engine Break-In Additive provides conventional motor oils with anti-wear additives like zinc and phosphorus (ZDDP) that are necessary to protect against premature camshaft and valvetrain wear. While designed for optimal engine break-in, this formula is ideal for extra anti-wear protection at any time. 1/2 bottle each oil change should do the trick. Part # 81403

Half Bottle (8oz.) when treating adds the following;

Capacity - Phosphorus - Zinc
12 quarts - 382 ppm - 460 ppm
10 quarts - 458 ppm - 552 ppm
8 quarts - 572 ppm - 690 ppm
6 quarts - 763 ppm - 920 ppm
5 quarts - 915 ppm - 1104 ppm
4 quarts - 1145 ppm - 1380 ppm

1 bottle (16oz) when treating adds the following;

Capacity - Phosphorus - Zinc
15 quarts - 610 ppm - 736 ppm
12 quarts - 763 ppm - 920 ppm
10 quarts - 915 ppm - 1104 ppm
8 quarts - 1145 ppm - 1380 ppm
7 quarts - 1307 ppm - 1577 ppm
6 quarts - 1525 ppm - 1840 ppm
5 quarts - 1830 ppm - 2208 ppm
4 quarts - 2288 ppm - 2760 ppm
1 quart - 9160 ppm - 11040 ppm

Are new synthetic oils harsh(er) on seals especially for older cars?
Also aren't API SL (or lower?) easier on seals than SM/N?

No. PAO can be harsh to seals (any elastomer seals), but there's few oils out there where PAO is the primary base oil. The ones that are, they usually have a good bit of ester which is an excellent seal conditioner. Group III synthetics are not a concern for seals.

That thing will be running long after our world ends. It and the slant6, 6.9 diesel and roaches will be the only things left.
