If it's a street motor and you're not making 800 HP I'd just use whatever you're gonna run after it's broke in!, 10W40 or somthing like that. Shouldn't make a tremendous difference whatever you use.

I have been hearing w/ a solid cam the oil would need zinc.

I am useing Valvoline VR-1 racing oil. Suppose to have zinc. That's what is in my new 360 that I hadn't fired up yet.

what does the cam company recomend?

I use Comp Cams oil additive, puts in all the ingredients new oils don't have, especially zinc, it's made for cam break in and they recommend adding to every oil change, probably a good idea but they are selling it.
Lots of stuff on the net about new oils and what they lack.

use a zinc oil additive!
Valvoline VR-1 racing does have zinc in it.
as does amsoil, royal purple, and a few others.
the newer diesel oils do NOT have zinc.

use Comp's additive to be on the safe side.

you can use whatever oil you want as long as you use a bottle of cam/engine break in additive. the additive takes up for the lack of zddp. after break in, drain oil, change filter and either use the same combo of oil+additive or use a good one like brad penn, joe gibbs that has good levels of zddp.

I used Valvoline VR-1 20W-50 on the last flat tappet engine I broke in about 3 months ago. I did not use any additives and had zero problems, but I did coat the cam and bottom of the lifters with the heavy Crane Cams lube.

I would suggest to anyone else to use the additive.
