I use Brad Penn 10w30 in mine. Works great for me
where did you get it? michael
Depends what lifter and cam you run. Flat tappet requires
Zinc and phosphors to remain happy, roller not so much. Rottella works well. I use Rottella to break the engine in then synthetic after.

All the above are good suggestions.The absolute key here is what Ray said.If you're running a flat tappet,which in you are,you MUST either run a "specalty" oil such as Brad Penn,or Joe Gibbs,or you MUST add an additive like Bob mentioned.The diesel oils such as Rotella used to be a good alternative,but even they have removed the zinc and phosphors to the point that they don't work either.Break it in well using only conventional[NO SYNTHETIC during break in],then either pay through the nose for the good stuff,or pay through the nose for the proper additive at EACH oil change.Like Ray,once the break in is done,I prefer the synthetic oils myself.This goes for all engines with a flat tappet cam and lifters,not just the "W" engines.
I have heard the same thing about the Rottella Don.
I buy all my Brad Penn oil from Buy Rite Auto in Caledonia, WI. Mike the owner has great prices. You will want to find a dealer near you. They sell it by the case for around $60.
I wouldn't run Rottella any more. They definatly have cut the additives. I think I can look into our data base and find the content. I think the only oils left for a flat tappit are the specialty oils. Although I do have a theory. After running a flat tappet for some time, you don't need the additives. BUT This may only work with a light valve spring. I have NEVER ran any special oil in my 327. Built in 88(?) No cam problems.
Correct Don, 12qts to a case. Great deal! $5/qt is cheaper than pennzoil at Autozone! If anyone is in the area, look Buy Rite Auto Parts up. A genuine, old fashioned auto parts store! Guys standing around the counter jawing about headers and carbs, pics of race cars they have sponsored, helped, work on, sold parts too etc behind the counter, full paint supplies area, everything in stock right there and prices even Advance and OReilly can't beat! I go there for everything!

and how long is break in? 500 mi.?
Depends on the rear gear, with 4:56 gear I will run my engine at the track two seasons on Dino oil before switching to synthetic. For a street driven car probably two oil changes.
So I found Brad Penn in Van Nuys 7 bucks per so next question 5 quarts with filter change (409 425 hp dual quad) their web site says the hp syn blend oil has all the zinc i'll need.
Good price,6 qts including filter.Since your engine has so few miles on it due to the valve train issues,NO kind of synthetic for about 3,000 miles.Modern rings and honing techniques have greatly reduced the needed time on the engine to seal the rings,but since we don't know exactly what parts are in there,not to mention the quality of the work,given the, valve train issues,be conservative,be safe.Once the engine has about 3-4000 miles,then a synthetic blend should be fine.
Zinc kills cats and I think they started using cats on diesels which could be why no more(or low) zinc in Rotella.
Amazon.com has Brad Penn for $70.88 (12 qts) with free shipping. That's under $6 per qt.
