friends first car was an former cab more-door Malibu. His dad pulled inline 250 6 out of his pickup and put it in the Bu as the 305 was locked up. We pulled the full buckets and console from a scrap GP and it got a backyard 2 tone paint job. That car made the rounds with at least 5 of us owning it back and forth at one time or another over the next 7 or 8 years. The torque of the 6 would squeal the tires pretty good actually. His dad put an inline 6 in a regal that he flipped as well. They were / are great motors. Finally my dad used it as a winter beater and the floors gave out LOL
