One one manifold, there is the correct 2863553 part number, but the number is one the backside and stamped into the iron itself? Looks unusual and can't say I've ever seen it that way before. Is there any reason why these would be that elway instead of numbers cast into it? I have an iphone 3 so I can't load pics yet. Any info please.

The t/a motors were built on Canada so they got that exhaust manifold. Some other 340 got them to so they are not strictly t/a. Barry should know.

I was told both sets came of an E-body. The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

They were not an AAR/TA specific part. Yep. I got a pristine set off of 70 340 4 speed Duster that had like 35,000 miles on it. He pulled the manifolds off at like 10,000 miles. My friend bought it and mini tubbed it and put in a 440. What a waste.
