79 trans am pontiac 400 upgrade path
Hello guys i am new to the pontiac world, i just bought a 1979 trans am, the motor is the pontiac 400, but i have an automatic. My car was one of the few ws7 performance packages that got the automatic when they started running out of borg-warners near the end of 79,
i wanted to know if i can upgrade my engine for big horsepower or swap it for a pontiac 400 from the early 70s that made 375 hp 475tq, which is easier, which is smarter?
