Is it better to portray this big block small mouth or stock big block grille ?

[HistoryBuff]

I painted this a long time ago with the small mouth it had when being tested in England. Then when they got it to Calif. they saw it needed a bigger grille mouth
So I could change it to be a stock looking 427 or I could leave it historically accurate? Once I get enough opinions I''ll try it at Mecum las Vegas on a 20" x 30" canvas. Opinions?
