you'll dump a LOT of money trying to pick up NA horsepower. Why dont you want to put gears in the car?

I dont want gears cut I drive alot on the interstate and dont want to kill my mpg. maybe 3.55 but no more than that. Im having it dynoed this week so will see what it puts down. Ive got dyno shets showing 320 from previous owner, so maybe itll be close to that.

These cars like to rev. 4.10's wont affect you as much as you think. look for one of the gear/tranny/tire calculators to find out what rpms you will be in. If I remember correctly, 4.10s are not much over 3k rpms @ 80mph.

I only have the 3.73's since I swapped in a whole rear-end that already had them. With the T56, its almost like going back to stock. Im on the fence between 4.30's and 4.56's.

Yeah seriously don't be afraid of the gears. 4.10s are fine on the highway. My 4.30s are just a hair too high for normal highway use
