Making a high-speed full-throttle pass in our 1972 Trans Am with new crossflow muffler from Waldron Exhaust.
The transverse-mount muffler uses tubing that's traditionally routed and is designed for improved airflow over an original. The numbers-matching 455 HO engine features a Nunzi hydraulic flat-tappet (222/232@ 0.050-inch duration) camshaft, but is otherwise stock.
you mean a fly by since it's a bird. man that thing is quick. it seems to effortlessly go through the gears. I don't hear it wind out forever like alot of small block chevys.
