American Gasser<\/a> was tasked with upgrading the powertrain and suspension on this Buick Regal T-Type<\/a>. In the engine bay they swapped a naturally aspirated 454 ci (7.4 L) LSX V8 capable of 627 hp and 586 lb-ft of torque. Exhaust routes through a custom stainless steel exhaust. Backing the LSX is a 6L80E six-speed automatic transmission and Ford 9-inch rear end. American Gasser powder coated the frame and added Allstar Performance control arms, QA1 coilovers, and Wilwood four-piston disc brakes. On the inside the company installed a Lokar Sport shifter, Dakota Digital gauges, American Autowire harness, and Vintage Air AC system. <\/p>\n
