From the comments section: A little info, original T-bolt, 496" Hi-Riser loaned to me by Jim & Jackie Gonia for these runs. Built by Panella Motorsports makes 919 hp, C-4 and 8" converter by Len Schneider, 4.30 rear 3375# with driver. My 454 Hi-Riser has iron heads and d-intake with 660's and makes 711 @ 6300. Thank everyone for your views and comments,  Phil (car owner) Nice ride, but in way stock drivetrain. The best time for the original was 11:40.

I remember when it took an Art Arfons car to get 900hp.
Amazing stuff these days with “power adders”

Well then... :)

11:40 is still freaking quick for a 52 year old factory car!
