The 63 wagon I got a couple of weeks ago had a new 6 cly. GM engine put in it in 1981. The person I bought it from couldn't remember what cubic inch engine it is. I phone the nearest GM dealer and I get the typical "our computer doesn't have that information". Anybody have any info. The part number on the bill is GM part number 6263028.

If it is an inline 6, it is probably a Target Master 250. GM used to sell brand new 250s along side the 350s in the early and mid 80s.
