This engine also shares nothing in common with the "Chevrolet 350" motor.
The Pontiac 350 was most common in Firebirds, Le Mans/Tempest/Custom S cars, and Ventura models. Usually found in 2 barrel form with the exception of the H.O. models that came with a 4 barrel carb/intake and more.
(At a stoplight)
Civic guy: "Hey" (while revving his 1.5L motor)... let's race!
Dude in Firebird: "Alright"
(Firebird kick's the living shit out of the poor Civic at the stop light)
Civic Guy: "Whoa! What engine do you have under that hood and what can I do to get my car to go faster?"
Dude in Firebird: "Pontiac 350 and uhhh... get a V8!"
