generally the conesnsus is:
for a car with a poweradder, go 3.73's or 3.90's
for a naturally aspirated car, go 4.10's or 4.30's

No first gear?![]()
Let me put it this way - I would NEVER buy a used Stang from one of you guys who put 4.10s on- Why ? because you just put 25 % more wear on i the engine for X miles .xlilzeex said:can someone tell me the diff and which 1 would be better..thinking of putting either a 3.73 or 4.10 gear but kinda iffy on which 1 i should get..

sixstringthing said:Im debating this too, and ive been debating it for a long time. The RPM and gas milease isn't what worries me, what does is the fact that so many claim that even if you feed it a LITTLE bit too much throttle when getting the car rolling or when shifting you get wheelspin (on street tires).... that could get SO annoying on a daily driven car IMO, along with the constantly having to shift. If it weren't for that I would have gotten the 4.10's a looong time ago.
