Most of the street 427s had 2x4 with most on a low riser (BJ and BK). Some had a 1x4 BV (3255-1),
I believe a few of the 428s came with a single Autolite carb.

Holley has a reference book on their carbs, and the # 3255 is listed as a factory carb for a 427 engine ( I assume a crate 427 MR engine). The 3255-1 was listed by Holley as a factory carb for a "race 427 Hi-Riser engine", both the 3255 and 3255-1's were rated as 780 cfm with the "leMans" bowls.
Early on, I believe the 427 comp cars were advertised as being equipped with Hi-Riser engines, although the vast majority of them as well the S/C's were equipped with either the medium risers or some with low risers. I believe there were a couple of cobra's that came equipped with high-riser heads, and I think the Turd had these heads at one point, as the Hi-Riser at one point was Ford's crate "Nascar" engine, and probably came with the 3255-1 carb, which is rarer of the 2. I believe both carbs are identical except for the List #.
