Cobra Owners Preferred Engine Oil Brand?

[AL427SBF]

Keithc8, I'm sold on Joe Gibbs. I would like to ask you what JG blend you would recommend with my motor, I've gone through their website and it seems several oils "apply" but one certainly has to be a best fit. Here are the specifics of my environment and expected driving style, the motor is brand new and still needs about 500 miles to finish break-in.

All Aluminum 427 SBF (DART Block, Edelbrock heads & manifold)
Comp Ratio: 10.4, Crank HP expected to be ~500
Residence: SF Area (CA), 28-105F are the yearly temp extremes
Weekend Driver but will hammer it on those nice northern CA open roads frequently
Car may sit for a couple of months during the rainy season
During Run-In: Oil Temp reached 180F, Fuel Pressure showed 60 psi - for what it's worth
Builder has Kendall GT-1 High Performance Racing Formula with Added Zinc, SAE 20W-50 shown in photo

My preference would be to get a JB blend that will give me maximum engine life, thousands & thousands of trouble free miles - don't want to rebuild it ever Any advice would be greatly appreciated, thanks.

I have a very similar setup. I talke to lake speed junior at Joe Gibbs and he recommended the hr1 15-50 hot rod oil. I would say you would be in the same boat. Their fully synthetic is great as well but lots of engine builders will tell you that synthetics tend to leak more.
