Of all the original A body 72 455-HO cars I've ever come across have all been the folded type. (Cars you could believe were originals and not changed.) Now, that number is VERY small as most HO engines have been messed with OR restored over the years. My old 72 GTO(now Jody's) had the boxed and was an August build...my HO lemans is a Jan 72 build and has the boxed too. GTO was Pontiac, Lemans was Fremont build.

I tried talking with Barry at Sonic Motors about this, but have never been able to hash out any pattern or rhyme or reason. My guess is the smooth ones are more prevalent in the Firebird HO's.

I will look at my original boxed one and see if I have a reproduction and compare the two. We need to distinguish b/n the two.

Great question, one I've often wondered about. Maybe OPH has some insight? Roger, you out there?
