So when these A bodies with hemis in them came from the factory, what did they have on them for exhaust? Is it possible to use the cast iron exhaust manifolds at all? Did they have any kind of pipes and mufflers? What were they using for a fuel system and tank?
 
They were equipped with new (for the time) Hooker headers, a mid pipe & 2 small mufflers that exited just shy of the rearend. As to fuel system, IIRC it was a 3/8" line & regular 'ol fuel pump. However most racers quickly added an electric fuel pump in addition to the mechanical one.

I remember a car called mr. Plymouth, it wasn`t "real" well known around here tho. I think it was in a few magazines tho.
 
STR, you DO realize? that hemi cars WERE NOT PRODUCTION

LOOK!! at all that fuel hose next to that exhaust LOL. Wonder what percentage of that exhaust went right into the dumpster "on arrival."

That’s a car modified after delivery by the racer.

Like was said, they came with machanical fuel pump and different exhaust (resonator w/round ends).

I think they had to have exhaust on the car for rules. Not sure if it had to be hooked up. Maybe that’s why that racer installed electric fuel pump lines are near the exhaust. It was never hooked up in racing conditions?

Is it me, or do the inside of those tailpipes have no soot on them. They look as clean as the outside.

Yes, they sure were innovative.
Dan´s first pic is of Landy´s 68 Charger, and here is a picture of the front part of the exhaust pipe.
If we stick to the ´68 SS A-Bodies they some how got away with just having the pipes hanging there. Rules constantly changed and Landy´s ´68 Charger that was put together well ahead of the ´68 season, and actually was to be his flag ship that year, had the pipes hooked up. Than NHRA a few month later let the A-Bodies through with the pipes not actually being hooked up.
For the 1970-season the pipes were no longer needed, but it wasn´t till 1971 NHRA totally changed this rule, and superseded the text shown above with simply, "Open exhaust with headers permitted. Tailpipes and/or mufflers optional. Outlet for open exhaust cannot exceed 4 inches in diameter"

I remember reading, that the exhaust was installed to get the car out only, w/ the thot that the buyer would dump it anyway. Never owned one myself , but was always a fan or them.
