I cant make out the first pic due to it being so small. There is a 2nd generations so called "HP" mainifolds that were for 340/360 manifolds as I understand it. If compared to say the 318 driver side you will notice the outlet is quite a bit larger on the 340/360 version. I believe that is what you have.

Per: http://www.mymopar.com/extcastnumb.htm

340 1969-70 Dart / Left 3614368

Perhaps a stock replacement?

That list has so much crappy info in it, it's not funny.

That's not even the correct number for that app listed.

3614368 LH 1972-74 A-body 340, 360

Yes with that casting date it's a 74 360 manifold, but, still same base as the earlier 340 piece..

Good to know CB, thank you.

Is there a better, more accurate exhaust casting reference list out there?
