Headers VS Manifolds

Just the drivers side but the only diffrence is that spine ridge, it is a 73 manifold, the passenger side is a 68. The set you have are awesome. I'm thinkin the drop on the transmission is what is causing the issue you are having. one thing you can try is loosening the bolts that hold the steering column to the floorpan and move the column over a lil' bit. I havent moved the column on mine. I'd be lookin to rework the trans tunnel and get a rubber mount for the trans (a solid mount there is askin for trouble). as was stated the engine mounts should be bolted to the engine tabs in the rearmost position(actually moves the engine forward in the chassis) that will also give the steering coupler more clearance. and after rechecking this morning no diffrence in slanty and v-8 k-frames on early a bodies. as far as the 273 manifolds being visually the same (choke*cough*gasp*) they are way diffrent visually,where they meet up to the head they are diffrent and the exit size is way way way diffrent, in fact there was an article published by mullin and co. showing that the 340 manifolds flow 5% less than race headers so I think the 340 manifolds are a good choice. Not posting this to discredit you just sharin the fact's. been playin with early a bodies for 29 years now and have done everything but big block in them ( that is in the work's for waggin II)
