I have a later style 67+ A body manifold on the driver's side of a 66 A body with no modifications to the steering shaft (manual steering). I had to grind on the collector flange of the manifold to clear the steering, quite a bit, but it fits with no interference. What I ground away was just extra casting material. I am using a magnum truck manifold on the pass. side. I have magnum heads anyway on an LA, but the magnum manifold will fit LA heads as well.

I am not sure about the best exhaust, but the easiest and least expensive for a daily driver is to use the stock 273 manifolds. Check this artical out regarding flow, someone sent it to me when I was asking a similar question. http://www.moparmusclemagazine.com/techarticles/155_0307_mopar_crate_engine_exhaust/We put a 360 in our 65 barracuda and used the stock manifolds. We stepped the outlets up to 2" then to 2 1/4" pipe and snaked the passenger side around the trans pan so both pipes come together (side by side)at the tranny cross member on the driver's side. It is really clean see attached. If I would have considered it earlier in the build, I would have modified the crossmember but I am happy with the way we did it. In order to get larger pipes in I went ahead and converted the kickdown to lokar. That really simplified the system and gave me more room.

these are my pro modified 340-360 1964-66 A-body engine mounting brackets, makes it a factory drop in swap.
So the mounting tabs are different on a 273 block than the 340 block? I had not even considered that problem.

Very informative, I am not going to worry about 11 hp at over 4 grand on this project. It may be worthwhile just to use the 273 manifolds and do a similar exhaust set up to yours. The lokar was already in the plans. Thanks very much!

After I read that article I measured a set of 318 A Body manifolds and the outlets on the ones I have are the same. That was what made my mind up.
The 273 manifolds will not "choke" your 340. Refer to the artical, I believe that the mule engine for those tests was a 300 HP 360.
My 360 does just fine. It would be nice to run headers and 2 1/2 pipes but on our car it is not worth the price or headache to me.
There is very little room to work with on the early A Bodies anyway.

 dont believe everything you read....
heck if i believed everything i read i would have never put a 440 in my 64 valiant... i saw in a couple magazines back then that said it wouldn't fit.. and you know how many oldheads said it would never fit... if you ask me it was easier to work on with the 440 then when it had the 360 in it....

take 2 tranny crossmembers & cut & weld them together so your exhaust pipe will tuck up nicely on each side. RR

If you look back at my first post, I said "I don't know about the best" and went on to say what I did and why. Are there better systems? of course there are. Could you build more horse power with headers and bigger pipe? yes.
I stand corrected in that there is a lot of room if you cut the fender wells.
The bottom line is that the 273 manifolds are an option and it is all personal preference and what an individual wants out of a car. I am talking ease of install, cheap, and clean. Once again, our 360 runs out just fine for a street car.
Believe what you read or not it is up to you.

You are certainly correct about the smallness, and that is the reason I started this thread. But if I read the article linked correctly, it is only a little over 10 hp loss. Maybe I am misreading the manifolds they used?
69 A body 318 manifolds, is there much difference between them and the 273 manifolds?
yes that is what that article says... but look at those 318 manifolds.. they don't have that choking bend like the 273 manifolds for an early a-body...
you can read this article http://www.compcams.com/Community/Articles/Details.asp?ID=-738676943 and it says the headders added 15hp over the best flowing 340 manifolds made. (the early ones..) now look at those early 340 manifolds and then look at the 273 early a-body manifold and tell me there isn't night and day between them....

That is good idea, the crossmember that has the torsion bars attached to it seems like it would be the biggest problem. That is why I like how moparmedic ran his over together on the drivers side. Pretty slick!

Are those fenderwells home made? They don't look like the 5215 Hookers I used to run on my race car.

Looks like the TTI:s wouldn't work with power steering? The Doug's seem to fit with power steering too...anyone have any experience with that? The TTI website didn't have the early A-body parts listed yet. Here's a budget solution that hasn't been mentioned, Durango/Dakota manifolds; http://www.geocities.com/lars_an_artist/durango.htmlHans

from what i hear you need a special $200 starter to run the tti's.
