That's what I use,but if you want the most Zinc content possible,pick up their VR-1 racing oil which carries .116 amount of Zinc.
Their "Not Street Legal" actually carries less at .112

Great info directly from a GM Powertrain engineer:
Oil Info

Re: Engine Oil and Muscle Cars
 

I recently came across a product called 'ZDDPlus' which is an oil additive for flat tappet motors. It bring the oil back to 'SF' graded oil (pre-1988) with one 4-ounce bottle per oil change. My shipment will be delivered this afternoon. I will follow up with more information and costs.

Feel free to ask questions. I have a flyer from the distributor but lack the ability to scan it to my computer.

Just bought 2 cases of Brad Penn. Had a lengthy discussion with Bob Rahilly (Rahmoc Racing Engines)in North Carolina about motor oil. He mixed 2 cases of 15W/40 for me. I believe this old Kendall refinery oil is the best we can get right now. It is the same Kendall GT-1 of years ago. Call him for info. (704) 782-1175. Reasonable pricing and fast shipping. https://www.yenko.net/ubbthreads/imag...iggthumpup.gif
