1979 Pontiac Trans Am had 6.6 liter 403 cubic inch engine with 220 HP with 35,265 miles. I replaced the engine and transmission to 5.7 liter, 350 cu in 385 HP high performance engine with 4 speed overdrive automatic transmission. Also changed rear gears to 342. The original engine, transmission and gears go with car, (all original). I also changed all gauges, speedometer, new digital dash by Dakota Digital. New AC, starter, alternator when engine was replaced. Car is Mayan Red with carmine red interior, T-Top. New cruise control, power windows and door locks, AM/FM CD player with 6x9 rear speakers. Mileage on new engine is 2,100 miles. Original mileage was 35,265; with new engine total is 37,365. Also changed with new engine was new 2 1/2 exhaust 2 flow master and chrome header - sounds good!
