79 Buick Lesabre
For various reasons I am out of the car-race business for a time, for this summer my driver has been a Geo Prizem... nice, fuel efficient, and SLOW... now I'm looking at a 79 LeSabre... it came with a 305, that much I know. The previos owner had a series of engines in it including a 396 and a 307 Olds... Presently it has a 400 in it according to the owner... I have always been a ford guy, but this is a good deal... now, my question... how the heck do i tell if its a bellybutten 400 or a pontiac 400?
