Treblig's doughnut?

Early A were facing straight back, It's strange that they made the 340's face forward! but I had them on my '65 at one time too. Too bad I couldn't remember how it was routed under there but I do remember that I had to have manual steering..? 318's were somewhere in the middle maybe a bit back. Good luck, show us what you come up with. And tell that hack exhaust shop to expand their minds, maybe they will grow some customers. I had an exhaust shop hard weld a transverse mounted motor exhaust manifold to the entire pipe to the rear hangers. It was a matter of days before the weld cracked as the motor rocks a bit front to back under acceleration. Pro, I dont think so.
