I have seen quite a bit of variation in the published specifications for track and other dimensions on 427's. This number is obviously bigger than the street cars but I see considerable variation on it other than that. One of the more common numbers I see is the competition and SC's having a 56" track. The number I'm after at the moment is a rear flange to flange dimension. Here's my maths...........
56" most common track I've seen
-10 1/2" (9 1/2"rim O.D (1/2 rim per side))
+ 7" (3 1/2" per side offset)
-3/4" (3/8" per side knockoff wheel adapter flange)
I make that 51 3/4" flange to flange or pretty darn close to an e-type. If any one can confirm those numbers and similar numbers, like front flange to flange, front a-arm lengths, upright dimensions, and so the list goes on...........this is the type of stuff that keeps me up at night!
Input and info appreciated.
