Kind of OT: 427 induction options?

'Jeb':

The '67 Shelby GT350 was available with the 428 engine (rated @ 355 HP) which had 2 600 cfm 4bbl. carbs on a 427 medium-riser intake under a one-piece 'Cobra' air cleaner.

The '68 Shelby Mustang is listed with a 427 C.I. engine option and I've read/heard that a very few Shelby Mustangs actually came with the 427 engine installed at the factory but I also understand that most early Mustangs with 427's were dealer - not factory installed.

In other words, a 427 Mustang is very rare.

A 2 X 4 barrel setup was used on many muscle cars of the era, including GTO's, big-block Mopars and Chevys as well as full-sized Fords with the 427 which was rated @ 427 @ 425 HP with the 2 4 bbl. option.

A single 4 bbl. 427 was used on the original AC Cobras and would be a fine choice for your Cobra replica.
