1977 W72 Trans Am
Im working on restoring a 77 W72 t/a. for you that dont know, W72 is a GM RPO code for the 400 engine package. in 77 is was a 200hp not like the 180hp L78 400 . it was the the same engine with gm upgrades. if you had it your build sheet would read
L78 400
W72 performance package
78-79 W72 was a 220hp 400
sorry for the school lesson, but you never know when there will be a test
pics of it before the tear down
