Gear's

Welcome to FABO!

That combo is stout!!! Gotta be a powerglide type run thru the traps in 2nd gear. I'd think a 1/2 sec increase is within your grasp if all the stars align.....I'd guess you'll pick up a few mph and cross the line 2/3rds thru 3rd gear with the 3.55's. From a et perspective, 3.91s/4.10s would probably be best, but you should pick up a ton and still have a decent gear for the street.
