Yes, Pontiac engine with wrong paint color. 350 2bbl /w auto, std interior in vg condition. Is that a build sheet on the rear floor? Check the date of battery will tell you when it was parked. Critters got in the car and under the hood. Probably got into the body as well so more inspection required. It's what the underneath looks like that will be telling. Nice car $2k - $8k depending on condition.
