Anyone here know what the deck clearance on a 400 is? Mine is running absolutely perfect right now, just planning ahead for some future mods and don't feel like tearing a head off just to check. I've heard 3 numbers, .125, .121 and .080 below the deck.

Is shifting early more a symptom of incorrect, or misadjusted linkage? Drove my big block 76 Cordoba for the first time after an engine swap the other night, and due to no registration or insurance yet, stuck to the alleys so speeds were extremely low. Can't recall what speed it was at, but...

Is the rod for the kick down different lengths between a 2 and 4 bbl?

I thought these valve covers I bought might be old Cal Customs, but there's no markings on them other than a stamp that says JAPAN 779 on the inside. It looks like you can remove the rectangular part in the center to put tall breathers in. The previous owner painted them. Anyone ever seen any...
