I need a set of A body 340 manifolds for my 65 273 Dart.Im running J heads on it and the original rectangular port manifolds block about a inch of port on them.The set you have would be a upgrade for my A body
I was gonna say, the factory didn't use exhaust manifold gaskets, stop doing this! If the surfaces aren't flat, true them up. Any tiny leaks should seal themself with carbon pretty quickly and if not, the surfaces aren't flat, fix it. I've removed plenty of aftermarket gaskets and reinstalled with no gasket to fix burned aftermarket gasket issues.
340 TA exhaust manifolds are the largest in volume. If your checking junk yards, look for the RT Dakota, Durango, or factory equipped headers. Little red express variation will fit!
I'm sorry but the Dakota RT was never equipped with headers from the factory nor was it ever equipped with RT cylinder heads which were aftermarket for Mopar.
To my knowledge the R/T dur, dak, were the same engine but mostly a suspension and drivetrain package. Although I still think it had a different program because you could burn out all day long
@@318Magnum Out oh the box the RT head flows around 20cfm more However it has thicker decks and 180cc runners. My ported set with 1.92 vales flow just under 270cfm at .550. Not bad for some iron. They also do not have the crack issues of the production mags.
You got to love all the 92/93 exhaust manifold talk ever since I sent the set out to Richard holdner for Dyno testing.
Yes I knew about them already but I definitely watched that one

The ones I have are just some 273/318 manifolds I just used pictures from the Internet for everything else all I can say is try eBay

Great point!
I put ‘70 340 manifolds on my ‘69 318 Barracuda. Wish I had never sold it.
I have a few of those stores but just gotta keep moving forward good luck to ya
👍💪
What do you use for gasket replacement? Do you get leaks?
For exhaust manifolds I don't use gaskets just bolt em on. I've had good luck with headers not too many leaks just using the regular gasket

The R/T heads were Mopar performance sold only and they aren't worth it from what I've heard
