1979 Trans-Am revving vortec 350 sbc single 3" exhaust flowmaster muffler
My friend's 79 TA with a single 3 inch Exhaust set up like a 4th gen. In fact he has modified 4th gen LT1 manifolds and Y pipe up front, built a 3" intermediate pipe to the rear axle, drops to 2.5" over the axle and goes into a 2.5" Flowmaster. Engine is a junkyard Vortec 350 with a cam and carburerated intake with a Holley 750 mech secondary carb. Also has a six speed trans. Drive shaft from a 2.8 liter Blazer fit perfect! I won't say anything about the secret Nitrous setup!
