Re: Recommended oil for a 352 (56 Super)

One other item is that 10w-30 will run cooler with less tendency for foaming than a heavier oil. Modern cars typically run in the 60-65 psi range using crescent type pumps, but I would put an oil closer to spec and see where that number ends up. The hydraulic lifters are calibrated for lighter oils as well.
