I'm pretty sure I've seen the ask before but my search didn't find it.

What oil is recommended for stock 289?

Depends a little on the condition and age of the engine.
Though 20W50 with high zinc content is what you would need.


I will someday think of something clever to say.

I only ever use Castrol GTX 20W50 ---- All we (my family) ever used in our old cars back in the early seventy's to mid eighty's ......I usually buy a few when on special and store under the bench in the mancave.

Drink

Good timing on this... it's just about time for me to dump the el-cheapo oil I put in for running in. Done about 700km now I think.

Does that include retro-fit roller?

I am not a fan of the retrofit roller option.
In any case - Yes.

Why not? Smaller base circle?
IMO in a street car it's not an issue, and I also haven't seen anything but conjecture about whether it's really an issue or not.

I just used a HO cam in mine with link bar lifters.

Good question:

A retro roller cam has the base circle ground down so it is very close to the shaft size - often the shaft has to be turned down as well. This is so the standard roller lifter has the support and more importantly is in the correct position to allow the spider to be installed.

This excessive reduction in the Cam ;
1) Reduces its torsional and longitudinal strength - thus the Cam will flex hence changing the Cams profile (so in effect changing the profile and reducing the actual lift of the Cam). This is gets worse as the spring rates increase.
2) Normally retro cams are SADI core which is a low quality cheap material. Even Ford specified Steel for their standard engines.
3) The Cam profile design and options are compromised due to the significantly reduce material available to get the desired shape. So your options are limited in terms of choice and the machined accuracy can often be compromised.

Now to do it correctly is to use a full size Cam based on a Billet Steel core and use Linked lifters.

In your case, a HO factory Cam is a full sized Cam and steel core so all is great. The use of Linked bar lifter is excellent. Your not using a retro cam (though I did think you had an after market Cam or do you mean HO cam in terms of the firing sequence - 351W / HO firing sequence is superior so that is great also.

I personally don't know why anyone would go the spider option when linked lifters are available.
Also, I can't believe that any reputable cam manufacturers would make a cam that is going to flex enough to change a cams profile. Have you actually seen any proof of this?

All I have seen is keyboard warrior conjecture.

I agree though the added cost is often a factor in people budgets. I to use linked bar lifters and steel core roller cams only.

As far as proof - no video though best engine builders in the world state it (and they would know) in any case I agree purely from applied logic. There are high loads being applied and a cast core that is not as strong, is thinner and has less material in it must flex more than a thicker steel billet core. Flex affects the profile that the valve sees so the designed cam profile as design is not being applied were it is needed.

I can see the argument that for a street engine (which needs to be defined) the owner would likely not feel any difference. This is because the profile change is minimal as the basic street profile does not have steep rams and high lift so the spring loads are lower. Having said that all roller lifter designs require higher spring loadings than a flat tappet as the ramp rates are higher otherwise you loose the major reason for going for a roller cam. Ford uses steel billet core for their roller cams from the factory - if they could save a few bucks then they would but they want the cam profile as designed to be present at the valve and they want the longevity for warrantee and reputation purposes.
