331, 354, 392 Exhaust manifolds

Postby horatiocaine » Mon May 16, 2011 8:41 pm

I have a 1954 New Yorker with 331 Hemi. Anyone know if 354 and 392 Hemi exhaust manifolds fit my 331?
Thanks

Yup, they sho nuff will. As for whether or not there are different mannyfolds with different body styles I don't know. But they will interchange. I think the early industrial 331s had round exhaust ports, so I'm not sure if those manifolds would interchange, but the rest will. Maybe a more experienced member will chime in about the body styles.

The 51-3 331s had the round ex ports. The 331/354 use ram horn center dump type while the 392 uses a straighter twords the back style that doesn't flow quite as well.

I got mine new at Amazon. It was cheaper than ebay at the time. Looks like it still is:

Well, sorry about that Rob. Looks like I wasn't paying attention. It says on the Amazon site, "Usually ships between 1-3 months." :o

Amazon still shows it as available though. I see one used, very good condition copy available for $13.61 from one of their resellers. I would grab it!

Thanks David. I got it. I also made a little progress on the heads today. Had lots of other stuff to do but I found the time to take the first out of the cleaner and rinse it off and put the second in. I will bead blast the first one tomorrow and take some pictures. They are gonna be beautiful.

Rob,

I think you're going to set a record for building a fun street Hemi for the lowest cost ever! :D

Most guys spend many, many thousands....

I recently bought a 392 out of a 58 Imperial, with the' Imperial' valve covers. I sure could use some help on how the front end of the engine should dress out. I have all the pulleys and brackets, but they are off the engine, and are totally confusing. Does somebody have a pix of how and where they should go? Also need some advice on a transmission. The one on the back of this monster is made of cast iron, and had the cable shift. How much trouble to go to a newer
Torqueflite? Thanks. Call, if you are lazy like me. 270 886 7933 or jagster911@bellsouth.net

Has anyone ever looked at the size of the outlet on these manifolds? It looks so small to work with a heavy-breather like the 392. I understand that they will interchange among all the years. What about headers?

The best flowing OEM mans are the "4 bolt" mans used on 300s & Chr truck hemis. Headers flow better but rust out can be annoying. Interchange is 54-58

"Imperial" valve covers are 1 year only items & therefore scarce compared to the "Firepower" ones. Adaptors for modern 727s are available. Hot Heads, Wilcap, T R Waters, & Quality Engineered Components. I've used QECs on 2 projects & like them. The Wilcap & Hot Heads are "full circle" style that are supposed to fully buttoned up w/o the oil pan on, if you can't drop your pan in car, you'd have to pull engine & tranny as a unit to get either out.
