OK, silly question...

I have a 383 small block crate engine (Patriot) ....We'll be running it at Bonneville. 6,000+RPM...... Any oil weight recommendations? I'm thinking synthetic oil may work best.

 

Some good oil discussion in Buddys Flatcad thread on landracing.com

 

if it is broke in synthetic---if not use a high quality conventional till it is then switch

 

30 weight?

 

Roller cam?

 

Nope

 

Why not call Patriot and see what they recommend?
Just a thought.
KK

 

Then I would not consider synthetic unless it is fortified with the appropriate amount of zinc dithiophosphate for use with flat tappets. Lots of threads on ZDDP on here and elsewhere.

 

I second this, just get a good high quality oil fortified with ZDDP, your cam will love you for it! Quaker State has a high mileage oil that comes in a maroon bottle, a little over fifteen bucks for five quarts at wally world.

 

I'm a Engine Builder and if I built the engine, I would want and expect you to ask ME!!

 

To prove I'm not a prick I'll try and help you. Did you get a build sheet with this engine? It would not be wise to make recommendations you are asking for without knowing bearing clearances and more, TR

 

Chaz, I've got a couple of extra cases of Mobile 1 Racing 0W-50 oil. It has high levels of ZDDP, and is full sythetic-it's what the Nascar guys run.

It sells for $16.99 quart, but I can't use it in this blown engine. If it would work for you, we could work something out,cheap!
