@@2000TA I have been on these cars since I was a child . Had a 76 trans sm 400 that was more if a dog than an overweight neighbor lady who would purposely wear tight outfits even though she weighed more than me. You know the type. Truthfully the 350 4 barrel from 77 to 79 be an ok option in thise cars, I just neverr seen one. I always thought the 305 chevy, though goid in its own right was not enough for these cars unless you talking a stripped regular firebird, at best.
@bighank796 I agree. My dad bought a black '78 WS6 new, sold it a little over a year later, then bought another '78 WS6 with a 400 last fall. I've had a '98 and a '00 WS6, so Trans Am life is on my family. The guy that owned this one died a couple of years ago, so i don't know much of the history. When I was decoding the VIN and cowl tag, I was surprised when it said chevy 350 was original to the car. I knew some came with the olds 403, but didn't know they were available with a Chevy engine, too. But the L in the VIN stands for the 170 hp, 4bbl, 350.
Unfortunately it would cost a lot to get it back to showroom condition and even they made fewer Formula's than Trans Am's, they don't hold Trans Am value. But, most old cars cost more to restore than they are worth. You restore it to enjoy it.
