Collaborative early a experiment

Well he certainly tried really hard to get a set of 70's 340 manifolds to work in my 64 with PS.

I am not sure about the 60's ones, I am willing to pay for the effort and shipping to try a 60's manifold if there is a chance it will work.

I really hate headers, but I really like power steering.

Has anyone considered modifying a set by cutting it and re-welding it back together ?

Well one thing is for sure and I have it documented...the 60s 340 exhaust manifold is designed a little different, here, see for yourself (SEE PICS). The 60s 340 is in the foreground (and right side of pic) and has no ribs.

I know for a fact that the 60s 340 pulls away from the steering box more than the 70s 340. It also rises higher, probably for the same reason. And most importantly it's absolutely flatter (no bulge) where it goes past the steering shaft area. The steering shaft area and the steering box area are the two places that are the problem with the 70s manifold in an early A.
Yes, I have seen 340 manifolds that have been cut and re-welded to change the angle of the exhaust flange but it would be difficult and very expensive to modify the area around the steering box!! I have read more than one thread (here on FABO) where other members have installed the 60s 340 in EARLY A cars with P/S and they worked!! It just hasn't been well documented and that's what I'm trying to do to help all you Early A people. I could sit back and sell all my manifolds to 67 and up members with no problem because sometimes it's difficult to keep up with orders. I haven't been advertising (in the for sale section) for over two months just so I could build up more inventory. I just got tired of early A owners asking me if my manifolds will in work their cars so I'm trying to do something about it. The 70s 340 probably won't work but I believe (from what I have read) that the 60s 340 will work without P/S and maybe maybe also with P/S.
