Considering these to swap a 383 into my 69 valiant. Are they better or worse than the originals ? I am open for suggestions on why I should or shouldn’t use these. Motor will probably be 400 horsepower. I’m not buying tti headers. Thanks
Anybody use the year one hp exhaust manifolds ?

That's a good price considering what some of these delusional people are asking for their 50 year old stuff. Id buy new.

I think there may be some fitment issues with the drivers side B body manifold in an A body.

No problem with '68-69 B-body manifolds on a B block. A little more issues with an RB, but they'll still work.

Yes. Might have to shorten the outer sleeve on the steering column, but not sure with a B block. You need to with an RB.
Thanks Jim.
Skeptical I am. Anything can be made to work but! What other issues to deal with!
Jim knows his stuff but a short response he gave.

Not mine Kim. I just googled “Mopar A body big block left side exhaust manifold” and that was one of the pics.
A few years ago I dynoed a motor with what was supposedly a set of the correct ones on it........ but didn’t really remember what it looked like.
More searching turned this up....... I don’t remember the one on the dyno looking like that down around the exit........ but it may have.

This is how a remember the one on the motor I dynoed looked.
A little different where it’s relieved for the steering column.
I guess it’s just a different year.
I’m glad I don’t need one.

Original. Had to move motor over 3/4 to fit power steering.
Pass side.

Probably because I have answered this question 500 times in the last 20 years. Yes, there are fitment issues, but we're building big block A-bodies with non-stock parts. Also every car is different. You won't like the clearance issues on my Barracuda, but it all works.

I'm sure you are tired of answering the same questions, Jim; but know this: I greatly appreciate any help I receive. I'm sure any of us that are venturing into making things work that weren't supposed to, do as well.
