Exactly, they were great motors. It was a very popular motor, it was in the monte carlos, impalas, v6 camaros, gran prix( GTP sc as well), buick regals, and many others. I didnt even know they had it back in the mid 70's. Heck it made it thru my girlfriends driving so it must be something special, and my "highschool hotrod" days. I beat my friend in his Iroc Z28 with it, and several eclipses. Now i drive it like im 60 years old(no joke). Ive been thinking about turning this car into a GN tribute, all black and possibly try to turbo the engine. or just buy a GS(supercharged).
