What is the diffrence between the 1966 340/350 i am wondering what the diffrence between the 340 wilcat and the 350 wildcat in 1966 pat
According to Buick's 1966 sales catalog, there was no "Wildcat 340". The 340 cubic inch engine came in two versions: 1) Wildcat 350, with 220 hp. This had a two bbl carb and 9.0:1 compression. It was standard in LeSabres and was also in the 4400 series station wagons. 2) Wildcat 375, like mine, with 260 hp. This has the 4bbl and 10.25:1 compression ratio. This was optional in LeSabres and Skylarks/Specials.
