Rislone makes a product called Engine Oil Supplement. (P/N 4405 at your local O'Reilly's). It contains:

•Rislone Engine Oil Supplement with Zinc Treatment is a petroleum oil performance supplement “booster” containing ZDDP (zinc dialkyldithiophosphate) Zinc and Phosphorus EP (extreme pressure) additives to help protect internal engine components including pistons, flat tappet camshafts, lifters, pushrod tips and the valvetrain.
•High performance formula stabilizes the motor oil to insure against viscosity and thermal breakdown.
•Reduces friction & wear, especially at start-up, helping to eliminate dry starts. Less friction means less wear and a cooler running, longer lasting engine.
•Clinging action keeps bearings and other internal engine parts lubricated where normal oil fails.
•Enhances regular motor oil turning it into a high performance lubricant for use in older engines and racing applications.
•Rislone works with all petroleum based motor oils including conventional, high mileage and synthetic formulas.

If added to the motor oil of your choice, this supplement should do the trick.

Thanks, Billy. I appreciate your advise on recommending products to "gearheads-in-training". I myself normally research a product for independent lab studies prior to using them. I use a Fram PH8A or their heavy duty version on my 440. Rislone is a name that has been in business since 1921 and has been used by famous "gearheads" such as Bobby Unser, Tommy Ivo, and Bill Reichert. Even Admiral Byrd used the products during his South pole expedition.

Again, I understand your concern and I appreciate your advise. I prefer not to gamble, but a take carefully calcualted risk with my engine.

Yes, I love skiing behind my '66SN, that's why I'm willing to do what is necessary to keep running. Question. What is a "poly" engine?

Poly=Polyshperical similar to how Hemi=Hemispherical. It has to do with the contour of the head. I have the same engine and have seen the bottom of the heads.. they're a strange shape. (poly heads)

Hang around a while, you gotta lot of learnin' to do.....Billy


If you do indeed research products before you use them, why would you use a Fram filter.They were at the bottom of the pile in research data..

Is this the total content of your research on Fram filters ???? Or did they pay you for that endorsment ?
I say again, hang around, you may teach us a new trick or two about these old boats.
Most here have a low opinion on Fram, sorry to bash your research.

As for your Grandfather, I have to agree. But:



Youth is wasted on the young and Wisdom on the OLD

Apology accepted and I am sure I will learn a thing or two as well.

And to be completely honest, my dad always used Fram and we never had an oil related failure.

The 312 you built and shipped to the UK sounds FAB-U-LOUS!!

My aunt's neighbor had a Thundercraft with a 312 in and a jet drive. That sound brings back memories.

Are you near Nawlins? (A friend of mine said that's how New Orleans is supposed to be spelled.)

GO MOPAR!!!

let me know if you are in the market for a parts engine.

still tinkering with the idea on just sending the extra engine out to get rebuilt and then selling (318-Poly)...not sure if there is any interest out there for it.

Yes

My 318 poly has a "few thousand hours" on it! Quote from the original owner. Still runs well!

A few thousand hours? What kind of a boat was it in? Do you know which make of water pump it is using...a Sherwood or Jabsco?

Peter,
I mess a lot with old cars and trucks and hang with a lot of "car buddies" on a daily basis. (a lot of them still drag race) Like us, they are all aware of the loss of zink in oil. Most with flat tappet engines will run the additive.

When building an engine, we usually use a roller cam in the rebuild. Easer to do than in a bacerds motor.

Another thing.... in the last few years is most are running E85 in their race cars.

A lot has changed since the days of "260"!
