Royal Purple( their regular 10W-40 SL will work or even better would be their XPR Racing )or Brad Penn 10W-40. You want something with a lot of ZDDP. A diesel oil could be used too but would not be my 1st choice.

I think Rotella T6 5w40 would work well in this application.

Chevron Delo 400 LE, 15w-40 and keep the OCI's short. I use it in my 70 Lincoln with a 460. It has the right ZDDP levels.

Stock 400 was a hydraulic (flat-tappet) cam that was pretty mild and I think it spec'd a 10W40.

I would go with an HDEO in 15W40. Depends on your budget, there are some boutique oils specifically designed for flat-tappet cams in older cars, but yours is not one that puts extreme pressure on the cam, so the HDEO would work well. Delo, Rotella, whatever, find one on sale...

^^2nd. RP told me that their 10W40 street oil has the most anti-wear out of all their other street oils. Then there`s also M1`s HM oils. They have 1000ppm of zddp.

10w30 Valvoline would be perfectly awesome for that car/engine.

They didn't have to use tractor oil in it back then....heck, your 5,000 mile old oil today is probably better than new oil back then.

The 440 in my 'Cuda ran on 10w30 white bottle Valvoline from 1994-2005 with 0 issues...and that includes sand in the gas tank from when it was sandblasted, and didn't get all of it out. What a mess....

I'd run dino Valvoline VR1 20W-50- it has lots of ZDDP. Second choice would be Rotella 15W-40.

All the 30wt suggestions are fine.
I'd suggest running a modern 5W-30 synthetic such as M1 or PP and bump up the phosphorus level with some Red Line Break In Additive:

http://www.redlineoil.com/Products.aspx?pcid=1

Call or email Dave at RL and he'll advice on proper doseage. One bottle is good for at least 5 oil changes.
Or simply run RL 0W-30 if you're okay with the cost.
