Yup, 326-455 Ponchos usually carry 6 quarts of oil. Don't know why that is, though. And in all fairness, JoeH is the pontiac man, I'm just the acolyte.

Although with all this upthrust and downthrust distributor mumbo-jumbo, now I know why the dist shot out of my Pontiac Lemans when the clamp came loose.

Must be an upthrust.
Anyway, we're stepping on Ike's thread. Ike, what setup you going with, and what vehicle?
