Hi Ron, The truck manifolds were used in the '55-56 NASCAR 300s so there is no reason that they won't fit in your '55 NYer. They have a 4-bolt exit flange and that port is 2.5" diameter. Remember now, there is no provision in these manifolds for heat for your carburetor choke. Sanderson Headers should be a fully viable alternative. I know they can be adapted to fit into the '57 Chrysler engine bay but don't personally know if anyone has fitted them into a '55-56.

Are the ones on the truck engines significantly different? If so I wonder if they would clear the steering and frame on the 55 New Yorker. Anybody know what size exhaust pipe attaches to the truck manifolds. The exhaust system on the 55 really chokes it down, just a disgustingly puny 1 3/4". I have been thinking of going to headers with a 2" - 2 1/2" exhaust so the sucker can breathe but if truck manifolds would do the trick, then maybe. Does anybody know?
