Besides the guys who are lucky enough to have those stock 2863900 / 2846729 manifolds, what are you using that worked well? I have 3751074 / 3751068 manifolds and asking for your help and opinions if there is something that works better. I have a 73 Swinger, auto trans, manual brakes. Also, to anyone who has installed Hedman 78030 headers, how bad are they to install? As you see I'm in the middle on deciding on my exhaust. Can't afford the TTI's and such. Thanks a bunch, Rog
 
u have to mill those manifolds about 5/16.headman headers won't work at all power steering. u will have to get the schuamaker headers.those are they only headers that will work with power steering.can see them at engine-swaps.com also check out bigblockdart.com go under the tech section.

I have a set of 1969 383 C body auto transmission manifolds still attached to the engine if you are interested. I would need to check condition so PM if you want me to take a look.
 
B-body HP manifolds fit just fine without milling, but better with. No problem with power steering.
 
After some researching, I found that the LH 3751068 is a HP 73-4 B Body maniflold. The RH 3751074 though is a LP E Body manifold. I'm thinking that since I have to pull the LP 3751074 off anyway, I might as go with a better match. The RH 3751071, which I believe is the match, is a 73-4 B Body HP manifold. Anyone have one laying around? Rog
 
I have a very nice 68-69 C Body HP manifold that would work well in there , $100 to your door .
 
Hi not to jump in the middle of your post but i have a question for JohnRR does your 69 Dart with the 383 have power steering. I have a 67 Dart with a 383 with a set of early sixties C body manifolds. They are a bit tight but fit OK have struggled trying to determine if the power steering will fit in there ok or not.
 
I'm interested in a right HP manifold . . . 2806898, 2806900, 2899970, 3751071, I believe these are right hand HP manifolds. Correct me if I have it wrong, I am using a 3751068 on the left. Thx . . . Rog

No , my car is manual steering but there is plenty og room , I never compared the A body left to the B body left but the 8 69 A body 383 cars did have power steering as an option so I guess it shouldn't be a problem . the Stock A body left manifold is the same basic manifold as the 68-69 C body HP manifold , if that is what you have you should be fine.

I replied to your PM , I read your original post wrong and I thought you needed the left manifold . Might have a right to sell though.
