(Note, while the 252 does exist, as I discuss below, the seller was wrong on several items in another ad, so it’s possible the seller meant this was an original 225 out of a 71 CJ-5)
Dan pointed out this rarish engine. The buick 252 is a 4.1L buick v6 with a longer stroke and larger displacement than it’s kissing cousin, the buick 231.
There was a little debate about whether this was a good engine or not on the OldsPower.com site. I don’t have any experience with this engine. In fact, I didn’t know it existed until recently. I still think I would have went with the 231/e.8L simply because they are easier to find. The 3.8L was rated at 110HP while the 4.1L is rated at 125HP for a 13% increase in horsepower with no increase in weight — maybe I’ll change my mind on this 🙂
Novak indicates this was built between 1978 and 1982. On the other hand, Wikipedia & Flatlanderracing.com indicate this was built from 1980-1984. Offroaders.com also mentions the 252.
