More exhaust manifolds

I've spent a lot of money trying to figure out which manifolds flow the best and which manifolds fit A bodies best. I have never found any factory "small block" manifold that had a 2 1/4" exit hole EXCEPT the 340 manifold. Then still, there were many 340 manifolds with only a 1 7/8" exit hole so NOT EVEN ALL 340 manifolds are created equal!! The only other manifolds that even come close to the 340 are the magnum/Dakota manifolds and some Jeep manifolds. These have a 2 1/8" exit hole (barely). I "machine" them out to just over 2 1/4" to help them match the 340 driver. But again, these large exit hole magnum/Dakota manifolds were only manufactured for a few years. If anyone can show me a good pic of the '74 manifold you're talking about with a scale/ruler over the exit hole, then I would be convinced (further educated). But I don't think it will ever happen. The only reason we have the few Dakota/magnum manifolds is because they were needed to suck all the power possible out of the magnum engines, especially the 360 magnum.
Now to be fair....there may be some other SB Mopar manifolds out there that have a large exit hole BUT THEY WILL NOT WORK ON AN A BODY. I know of a least one SB Mopar large hole (2 1/8") manifold that doesn't fit A bodies very well at all.
This is why I sell the other types of large hole manifolds (magnum passenger/Dakota driver's/small hole 340 manifolds etc) because some members buy them for their early Dodge truck or Hot Rod build that is not an A body. While some of my manifolds won't fit an A body they will fit Polaras and other types of B bodies as well. So for those who don't like, want or can't afford headers I offer these alternatives.

I am currently researching the late 60s 340 "large hole" manifold and am looking for someone to try it on an early A body (I have two in stock right now!!). The late 60s 340 is designed differently from the 70s 340, it is also more rare. It has the same 2 1/4" exit hole but is sleeker, less bulky and will give you more clearance around the steering box, steering shaft areas (SEE PICS). Hopefully I can find a simple solution for the early A bodies because I'm always getting requests for manifolds that fit the early As.


The last pic is a Dakota after machining!!
