chrysler 340 engine help

Hello all, New to the forum and as I have read from past posts y'all don't mind a post from a Century owner from time to time. Own a beautiful 18ft 74 Resorter with Chrysler LM340 and 1;1 velvet drive. I am have an interesting issue with just the end plate of the right exhaust manifold getting hot, Specifically right at number 1 cylinder, exhaust manifold is new and cool to touch but end plate getting so hot it is burning the shape of the orifice inside the exhaust manifold through the new paint. Motor is a fresh rebuild, less that 10 hours. Edelbrock 600cfm carb, new plugs (champion). Runs cool and great oil pressure. Had boat in water today and after 10 min the problem side was 20 degree hotter @ 129 vs 109 for the other.

Anyone have similar experiences or can send me in the right direction?

Thanks again!

Welcome to the site. There are enough people here that have that engine that ought to be able to tell if its plumbed correctly. Chryslers plumbing is convoluted. Post some pics of your engine. What color is your Resorter?

Rich,
Please understand that a Barr is not the same as the OEM manifold and plumbing most likely would be different. Is there a reason you only changed the starboard side? Since the paint is burning off, I'd have to say there's an air pocket on the high end.

Rich: no worries, there are a number of us here on the site who also own a Century. How about some photos?

If you've never been on Hurrikain. Com they specialize in Chrysler and also have original operating manuals if you do not have one.

Rich,
For pictures, use the "post reply" and not the "quick reply". Click on the icon of the tree with the up arrow. A box will come up allowing you to browse your computer for the picture.

Rich,
Nice! I always enjoy the classic lines of the Resorters. Did Century put boot strips on their hulls in 74 or were they just removed? Did you remove the boarding ladder and add the platform? What's the vent in the side of the dog house for? Thanks for the pictures and yes, get those pictures of the engine posted.

Nice looking boat. I like how you cut the bunks back so that it sits on that #3 so nicely.

Looks like a Bronco tow vehicle, very nice

Apologies now to any of the purists who may be offended by my decal, imitation is the sincerest form of flattery.

Rich,
What was the problem? Did the PO remove the USCG mandated ventilation?

Riley, that's hilarious....believe me some things I don't take too seriously....myself included. Fact is I love this boat, fun, easy to work on and I enjoy looking at it. lol More than I can say for my first two wives!

Oldcuda, great boat! (and tow rig)....

In 75 Century changed the Resorter to that similar (or same) "Italian Brown" but it was full brown to the keel,, not just above waterline,,...what year is yours?
