AMC Gremlins got a V8 swap a lot as well. I thought about swapping the straight six in my pacer for a V8, but hated the way the car looked. Was going to trade it in on a 1981 Pontiac Trans Am(Black & Gold), but parents wouldn't co-sign. Sold it to a used car lot and got a 1975 2 door Chevy Nova. Loved that car. Straight six -automatic went bye bye - put in 350 and Muncie 4 speed.
