I have a few options on the shelf (literally)...
Stock 68-70 340 exhaust - probably won't fit... So....
I have a set of 66 273 exhaust manifolds that I can open up a bit for better flow and will fit in the early A engine compartment...
Or a set of 68-69 stock 318 manifolds....
Or buy a good set of early A headers.... (but I don't want to cut the fenderwells...)
Then dual 2 1/4 with x-pipe into dymomax mufflers and bend to exit on each side behind the rear tires (so I can drive with the rear tailgate window down and not get exhaust fumes in the car)...
I just have to build a 360 for it and bolt the new brake lines and front brakes in, then worry about scrounging an interior together... I have a few different parts dashes, just have to decide which one to go with and get it together....
