The light duty trucks (1/2 to 1 ton) with 292 used practically the same manifold as the smaller 6 cyl. engines. There would be no advantage going to one of those. The larger trucks had an ex. manifold with a larger outlet. 2 1/2 in. It is pointed straight down & the smaller ones outlet slants to the rear. They are pretty rare. Be careful useing used 292 manifolds as they are generally warped or cracked. The ex. on them run really hot. The big manifold has no heat riser valve.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
