The Mighty 390 in my 68 Colony Park and the 400 in my family's 74 LTD came listed as 4V's...Which I could figure out,each pair of pistons making one V...What the heck is a 2V?Have never heard of a four cylinder 429.Apparently,it's not a Boss 429,or it would say that on top.Looks pretty dang good for what's probably the original engine.Clean,well aged and not covered with after-market add-ons.
