agreeing with what you are saying..I didn't know that those neat f.i. 300s had a dual outlet exhaust manifold too--the Intake manifolds took my breath away. The four bbl OHC Pontiacs had the best best exhausts I had seen sofar-do you have a shot of these Ford exhaust manifolds? The best thing Chevy had for their 194/292 series would be the 2-1/2" single outlet early 292 exhaust-kinda hard to find these days, they usually came on the dump trucks and school buses--very few are the real item on ebay-the ebay stuff is usually something 250, or something perhaps shared with the 250 well into the "smog" era. The factories rarely have anything too neat for the inline sixes. Now I mean for the American vehicles. Neat, but almost unknown, old "Canadian Ford" flathead, heads, and perhaps a bunch of South American, and Austrailian goodies are the exception, and pretty hard to get.
