What engine oil to put in my SBF

[WarrenG]

My engine builder recommended Shell Rotella T 15W - 40 when I bought the engine (1965-289 stroked to 331) and still recommends it. I've 8600 trouble free miles on it so far, all street though, no racing.

Rune,

Don't know anything about small blocks. Having said that:

On my 460 there's a tapped hole just above the mechanical fuel pump location on the front driver's side of the block. This hole leads to the output side (gallery) of the oil pump, so that's where I put mine.

Also on the 460, there's another place on the top rear center of the block where the oil pressure gauge fits. Some have used that spot and report it works, too, although I've not personally seen it done.

As a third option, if you have a remote filter and/or an oil cooler, Canton has a schematic for you to use to tee into that line.

Finally, there's another option, also I think from Canton, to put an adapter between the filter and the block to accept the output of the Accusump.

I don't know of anyone using the check valve. Maybe someone else can contribute some experience.

A very big caution: don't install the Accusump piping incorrectly! It's easy to overthink this and plumb it in backwards, resulting in no oil pressure.

Hope this helps,

Tom

How much?????? I smell a business oppurtunity. Anybody want to buy some bootleg RP?

With most blocks it's difficult to plumb it to the back of the engine. It can be done, though. The front of the engine (where the pump is) will lose pressure before the rear will. Then the Accusump will force oil into the system, but in reverse order. Like a wave it will try to fight any incoming oil from the pump.

If you have no other external oiling systems (cooler, remote filter), then you should put a sandwich adapter between the filter and the block. It should have one hole for the resevoir feed. That's the easiest and most reliable way to do it.

I k now very little about big blocks. But on the windsor engine, that hole is for the oil pressure gauge. It's only 1/4" NPT. Not nearly big enough for a resevoir feed. That port should be at least 1/2" NPT, fed by a -10 or -12 line.

The small block doesn't have this port

If you're using the resevoir with anything but the single port block adapter, you'll need the check valve. Otherwise, the oil will follow the path of least resistance, and flow right back to the pan instead of the higher pressure oil galley.
