WTB 1972 350 4x4 Exhaust Manifolds 3989036

Need a pair of Exhaust manifolds for the new project truck. Looking for casting 3989036. These are the Ram Horn straight dump for a 1972 Chevy SB 350. Thanks in advance for the help.

Re: WTB 1972 350 4x4 Exhaust Manifolds 3989036

I have a serviceable pair that came off a 1972 C50. I am putting the engine and trans in my 49 Studebaker farm truck, and can't used these manifolds (well, I could use the right side, but prefer to make them match, so I am using some different log style. Would rather use these, but the left one interferes with my steering box.

I think the number you cited is a 1970 number. Don't believe it was used in 1972, but I am not a manifold expert by any means, and could be wrong.

The ones I have are drilled for smog, but the holes have been plugged. I don't know for a fact they are original the C50. One is 386711, which is for certain a 1972 number, but I didn't see a casting number on the other one. They look alike. Don't know about truck usage, but that number was used on both sides of a 1972 Corvette with the LT-1. One broken stud. I haven't tried pulling it. I don't think I even soaked it with penetrating oil. Either it will come out or you end up drilling and tapping.

I can send you pics, or post them here. PM me if you want me to send pics to an email address.

$100 plus actual shipping for the pair.

Re: WTB 1972 350 4x4 Exhaust Manifolds 3989036

I think what Kinsolver72 just posted is probably what you want. I can't read the casting number. Not sure how serious you are about originality.

I have a pair, but numbers are not even close to what you posted.

Also, I MAY decide to use one of them. Just can't make up my mind right now.

Mine are 386711 and 14081238. The 386711 was commonly used on Corvettes in 1971 & 1972.

They have provisions for smog tubes, but the holes are plugged with metal plugs.

I promised pics, so here they are. Sorry for the crappy quality.
