I scanned through the posts in the thread and didn't notice anyone mentioning the fact that the 69 335hp 383 motor had positive deck height flat top pistons originally.
If you mention that, somebody will insist that they weren't +dh, so I never say anything.
How much + have you measured them?
Long ago, far far away. It was less than .100 , if my yellow book surfaces I will check to see if it mentions it.
I've measured a few unaltered originals, they were all below the deck. The NHRA spec is like 0.020" proud, I have never seen one from the factory like that.
I knew a guy that ran an A body 383 car in Super Stock had to actually grind on the pistons to clear the 906 heads where the head overhung the bore.
The 1.932" CH piston was used in at least 1968 and 69 383, maybe 1970 too.
