Joe Lucia...part ID

[Chris L.]

Hi Joe...Have a set of manifolds and trying to figure what they go on. I believe they came from a 396, but not sure. Casting number 3916173 RH and 6786068 LH. Any clue what they go to?? Thanks

I think the "3916173" is actually 3916178. If so, that manifold was used for 1968-70 passenger car, Chevelle, Camaro and Nova big block applications. It is a "log" type manifold used for the right side. All of these had AIR bosses, but only some were drilled and tapped.

The "6786068" is a mystery to me. That's not even a Chevrolet part number. For casting numbers, it's easy to confuse many of the numerals with others. However, the "7" is one that's usually pretty distinct. The first digit could actually be a "3" but with the second almost certainly a "7", it's a mystery. That's because there were no Mark IV big block manifold casting numbers that began with "37".

Thanks Joe...I'll check the numbers again. I might have written them down wrong.
