Speaking of air, should you need vintage air for your tires....we have special containers with the specific air that would be correct for your vintage Shelby.

Please provide us your specific build date and we can provide you with a proper qoute and special SAAC pricing.

Thank you

Agreed... Wait till you ask how much air pressure is ideal, or what do you think about running a CAUTION fan sticker, the flood gates will open up.

Vintage air. Creatively hilarious! Scary part is there might be an actual niche market for it.

How much Z does one need???

We have used mobil 1 15w50 with 1200 for years.  One of our cars has a 428 with a high lift and duration.  No problems so far

Randy:
Exactly. Or long term use and wear and observation during tear-downs. Mobil 1 absolutely does not contain enough ZDDP to protect a flat tappet cam.
I use Mobil one in my Lincoln and the Saab V6 cars.  I also had an issue with Castrol. I used it on my Turbo Toyota. It would pull enough oil in smoke during high vacuum on deacceleration. I changed to the Kendall and it stopped completely.
Too many personal experiences.   I'll stick with the Penn Grade on the Shelby.
I am not overly enthralled with 18-20 PSI at Idle hot and 55PSI hot at 3000 +-.

To be fair Tony the 'Caution fan' decal does have a use. It works well when you lean on one and crack it. It'll hold it together while the glue cures.

For what it's worth,.... the 5-50 Full Synthetic Motorcraft oil has been run in my race car for 7 years at full temp in 30-40 minute sessions in 90 degree heat at 7-8000rpm almost every shift.

Only blown one motor.....

Small Block roller motor?  Roller and Flat Tappet cams have many different requirements. If you spend a lot of time on the FE forums and others we see a very common trend of flat tappet cam issues. Especially with new break-ins. When most of the builders of renown suggest and regularly use a particular product then I tend to follow their lead.  As for the Penn Grade is has always been one of the best offerings out there.
