well not really sure what your looking for. but my kind of opinion of the two would be, if you got an auto go with the 4.10's as most everyone else would say. now if your manual get the 3.73's.
buuut my example of a draw back of the 4.10's... only had experience with these so cant say anything about the 3.73's.
it actually happend tonight, and as bad as street racing is, me and a buddy were. it was a 88' GT AOD with 4.10's, and a 97' Pontiac Grand Prix GTP. the GT was pretty much stock, gears, shift kit, full exhaust, and i think bumped timing but thats really it. the GTP had a lot more.. and this guy talks **** alllllll the time, i just sold my GTP and he always said mine was stock, which i had a cam and stuff so ya.. not stock. but anyway, we get on it from like a 10 roll and the GTP jumped, the GT stopped the pull and held it. the GT did pull a lil and got about a half a car on him and stayed there. buuuut the draw back here.. after my book lol, after about 80 mph, the GT ran out of gear. his acceleration slowed down in a way. so the GTP started to pull, well by this time the GT gets out of it. but i consider the GT to have won. but ya 4.10's are steep and might hurt ya.. just from my experiences. but ya that race was a really big deal to me and the GT owner, cuz the GTP talked sooooo much ****, and the funny thing was.. my "stock" GTP compared to his, pulllllled from the GT
ok ya im done... [&:] (i had to tell someone about this race, i was excited lol)
