Thanks! At what rpm do you want to be crossing the traps at? You can take a look at one of the gear calculators that you can google. 4.11 gears may work for now if depending on what rpm you want to be turning, but if you add more power down the road you could be out of gear. Bob

for forced induction? i cant give an approximate good vote here but i theint 4.10s with FI youll be rowing faster than hell i'd think...i know guys with auto's are usually in the 3.0-3.50 range...more low 3's...im going to vote for 3.50's

A lot of F Body's running 9.0 in the 1/4 with 28" tall tires use a 3.70 gear. Mine did with a Powerglide. Bob
