Odds are you have 273s....they suck....cars a complete mutt with em...5th is something you never use as the cars doggy enuf, never mind slipping it into 5th..
I swapped 355s with 5spd for 2 seasons....no complaints...mpg was better, much more fun to drive, more sack and I actually could use 5th for a change....mid range hit was way better, 70 mph was a sweet spot and passing cars is a hoot as it will actually move some....speedo needed a gear swap and was pretty much right on....all goodness...
In the never ending quest for more hit I stepped up to 373s....mpg took a slight dump as I romp on it more often...stay out of it and the mpg is just fine.....first gear can be real short...from there on out its all goodness...midrange and upper pull is even better....you always have 5th and youll find yourself using it more often...
speedo gear remained the same and is off by maybe 3-4 mph...
choose your weapon...both are nice....373's and the 5spd seem to go hand in hand...for me I would not opt for anything higher than the 373s....depends somewhat on your goals...street car or a 1/4 mile terror...
