One of moms old HS friends was a former drag racer and later school autoshop teacher. He drove around a junky looking Mazda pickup in which he transplanted a 351 with two 4 barrels on it. It just as well have had a rocket motor jammed in it :-)
Wasn't a muscle car but it took off like a scalded dog. Man I loved that car.
Destroyed it on a wet winding road late at night. Sad end to a good car.
