Hydraulic Flat Tappet Cam: So Far So Good
Well I've logged my 1st 70 miles since my hydraulic flat tappet cam and Aerohead Racing prepared 601's were installed last weekend, and my oil pressure is good, as well as my engine temperature.
Initially, I used 1 bottle of Lucas, 2 bottles of Rislone 3X break in oil additive, and 4 quarts of Shell Rotella T4 15W-40.
At 50 miles, I have changed the oil and went with 2 bottles of Rislone 3X ZDDP and Phosphorous additive along with 4 quarts of Rotella T4 15W-40. I intend to change my oil filter at 1,000 miles for a cut and inspection. Hopefully, my luck holds and my cam lives a long life.

Re: Hydraulic Flat Tappet Cam: So Far So Good
Be careful. Too much ZDDP can also do damage.
The "sweet spot" is
TYPICAL TEST RESULTS INDICATE: GASOLINE ENGINES
With typical SN rated oil at a 7% dosage rate expect levels to be raised to a total of:
Zn Zinc 1700 - 1800 ppm
P Phosphorous 1500 - 1600 ppm
But I certainly would run more than I needed at least until the first oil change.
After that, shoot for the levels indicated above.

How many different products have you mixed together now? 5? 6? Not knowing if any one of them doesn't like the other(s)?
Seems like a whole lot of trouble, when one product would have accomplished the break-in, and another is your long-term solution. With no mixing required.

I don't like making things harder than they need to be.

Synthetic oils do not absorb heat well and would not be a good choice for a cast iron engine with marginal cooling. The 3rd generation F-body GM cars are pledged with inadequate radiators.
In addition to the fact that I live in the Rio GrandeValley of Texas 5 miles from the US/Mexico Border. Amsoil is not a common product in the area.

There's plenty of retail lovations that carry Amsoil near you I'm sure. What's you zip code? Try Burton Auto Supply in Brownsville.
Amsoil will also ship to your door. No problem.
Synthetics handle heat MUCH better than conventional. That's really their biggest advantage. Amsoil Dominator can handle sustained 300 degrees with no degradation. Amsoil 10w40 premium protection was designed in the 60's - it is exactly what your engine needs. No additives required.

Wasn't the reason they took most of the zddp out of newer oils because supposedly the zddp caused the catalytic converters to fail prematurely? I don't really see how that would be the case since cars in the 70's and 80's and 90's all ran oils with the higher zddp content and nobody every complained about that back then.

Re: Hydraulic Flat Tappet Cam: So Far So Good
Personally, I use this. With a quality name brand oil of my choice.
I do oil & filter changes at 3000 miles (SBC). I use 2 oz then, and add the other 2 oz 1500 miles later. Adding some Marvel Mystery oil does not hurt either. It works great to help loosen and trap contaminants and keep them in suspension, so that the oil filter can remove them. It keeps the inside of your engine cleaner.
When I use up my 30 bottles of Howards additive, I'm going to seriously take a look at that Rislone additive.

As I understand it, removing ZDDP was for more than just because of catalytic converters, but for sensors as well. Wasn't a problem for 80's emissions systems, though.
True, AMSOIL isn't selling for 60's prices anymore, but what was your gross income in the 60's? $100 a week was considered a very good living in the 60's.
