Four years ago I retro fit the IRS option into my carbon fiber FFR MK 1 Cobra. The aluminum 99 Cobra pumpkin had 3.27 gears. 3.55s better suited my small block and after one session at Willow Springs I took out the 3.27s.
Last year I built a small block FFR with IRS for my friend, the late Dick Smith. This street only FFR was for coastal cruises and other social events. He was pleased with the standard 3.27 gears.
Dick's 427 race car #198 has 3.50 rear gears. The ultra built 427 side oiler was not well suited for street (cooling) but he did drive it on some NorCal coastal cruises that I participated in. The car had 3.31s at Daytona in 1967 when radar proved the 198 miles per hour record laps.
I was given the honor of doing some laps in the #198 car last year at Willow Springs. It's the most powerful car I have driven.
In my opinion 3.27s would be ideal in a street 427 Cobra with a 400 hp.
