PJack,
I am not for certain if the vintage Pontiac cranks used "straight shot" oiling or not. They may have had some early version of it, however I beleive Crower is credited with the modern straight shot oiling system we are implementing of these cranks.
As far as a timeframe on the 3.25 inch main cranks we just flat out don't know yet. As soon as we have what we beleive to be reliable information, you guys will be the first to know.
