340 Exhaust Manifolds on Early A-Body??

340 logs fit, The Hi-po ones. I had them on my first 340 '65, BUT I remembered running the skinny 67 biscuit engine mounts on that car, stock 65 fatties may change things. I think the driver side had to be ground a tad to clear the steering box, but it was just a touch with a die grinder. The Magnum manifolds flow better, Ill have to look into the Durango's. YOull need a 90 oil adapter with the 340's or run a very short oil filter. I used a relocation kit as I couldnt get the filter down there to change and if I did, I spilled a quart of oil on the ground trying to screw it on/off. Someone suggested Magnum Dakota headers but they look like they would interfer with the steering coupler, but that was about it, unique design for sure.
