Can anyone check out a Chryco part number for me? Intake manifold gasket 1735765. The gasket is made up of 4 parts rivetted together. A steel gasket on each side of a 2 piece 1/4 inch thick steel spacer. They came in a box of NOS Chryco and Mopar parts and I can't find that number anywhere on the net. Thanks for any help!
Looks like the same thing found on a 354 hemi truck head due to the tall center port. It covers a water passage in that application. Passenger car heads have a much shorter passage in that position which is an exhaust crossover passage.
I found a reference on the net that said it was a 1957 Mopar DT V8 gasket. I'll assume DT means Dodge truck.
That part number appears to be a 1957 part number. Maybe the gaskets are 1/4" thick to make up for how much the heads need to be milled
Those two round ports are for cooling water as well as the center port on the truck/marine (heavy duty use) heads.
