Exhaust Manifold Without Imco 170/200 1965-1967 is rated 3.3333 out of 5 by 3.
Rated 1 out of 5 by from Caution I received the first #EXM-1 exhaust manifold and to my disappointment I noted the following (See 1, 4, and 6 pictures): 1. Blockage caused by excessive mold flash (and what appears to be a large nail) in cylinder #5 port which would impede the exhaust gases from cylinders 5 and 6 from escaping. 2. There is also a large sink on top of the manifold in the cylinder port 3 & 4 area and flash inside in the same area. 3. Two of the bolt hole flanges (where the long bolts go) were not square to the holes which would result in the bolts and air conditioning bracket not being able to seat properly. 4. The heat riser tube hole was machined undersized and the ¼” diameter heat riser tube for the automatic choke would not be able to be fitted in the manifold without drilling the hole to fit (and existing hole was clogged with metal chips). 5. Exhaust flange tapped holes were not the correct size (they were 3/8-16 UNC, should have been 7/16-14 UNC). I returned the manifold (C J Pony Parts paid for the return shipping) and received a replacement. I inspected the replacement manifold and all looked good except items 2, 3, 4 and 5 above. I figured I could grind the manifold bolt flanges (the (2) long bolt hole areas) so the A/C bracket and bottom bolt would seat correctly. I drilled out the auto choke heat riser tube hole to ¼” so the tube would fit and figured I could obtain some correct size studs/nuts for the flange (needed 3/8-16 UNC x 2 ¼” long hardened studs and lock nuts). After those modifications I decided to bead blast the paint off of the manifold so I could spray it with a high temperature silica/ceramic coating. After bead blasting the manifold to my horror there were voids in the casting and they were filled with what appeared to be epoxy! (See 7, 8 and 9 pictures). If I had not decided to bead blast the manifold and installed it I am sure the epoxy would have blown out in short order and I would be replacing the manifold again. I must give kudos to C. J. Pony Parts for trying to get me a decent manifold, however, they really ought to dump their existing vendor and find another so customers won’t receive sub-quality manifolds.

Rated 4 out of 5 by from Does what it's supposed to do Fit perfectly with one exception : The bolt holes for the exhaust pipe connection were a different size than the original. Also, the interior threads were painted, causing difficulty in finding the right size bolts.

Hi   do you have the manifold studs and nuts in stock for this manifold ?             Kind regards gary

Asked by: gazman
No they do not. The #F522 stud/nut kit on their website has 7/16-14 UNC threads (they will fit stock OEM manifolds only). The tapped holes in the 6-Cylinder 170/200 cubic inch #EXM1 after market manifold they sell has 3/8-16 UNC threads. You will have to either drill out the manifold holes and re-tap to 7/16-14 UNC (drill/tap at your own risk) or source 3/8-16 UNC x 2 1/4" long hardened studs and lock nuts. They are aware of this issue. They should mention this on their part description.

Does this manifold have the hole for automatic choke?

Asked by: fireball47
It has a 3/16" hole. OEM auto choke hole is 1/4". Check your auto choke heat riser tube before drilling manifold hole.
