Tom, it is a 250 horse 348 with a 3 in the tree. It was a turbo glide till my dad hit a rock in the road. he had the trany rebuilt but it leaked like crazy. So fed up with the leak he put in the three speed.50 years in the same family, that's pretty special! We hav few members on site who still have their original purchases from that same era . You guys should be lauded for your preservation efforts!
Which engine/transmission combination does your vehicle have? Is it the 250 horse 348 or something a little peppier?
Best,
