3.73s or 4.10s????????????
 

i have a 385 ci motor with a th350 trans
its still gonna be a daily driver, but ima take it to the stirp every once in a while
i dont know if i should go with 3.73s to 4.10s in the rear
any suggestions?

they both work well on the street, depending on tire size and
is this a 10blt? 3:73 worked great for me on a street/strip car,
with out a problem www.tomsdifferential.com,
www.strangeengineering.net, i have worked with both these guys,
and they won't gear you wrong, good luck :wink: MADE IN USA

After years of running 3.73' on the street and racing with them, I put 4.10's in my car and wish I would have put 3.73's back in instead. Of course, Pontiac's don'tlike to turn a whole lot of rpm's.

is it 1/4 are 1/8 mile track?

im one of his fraiends and im sure it'll be both cause we have penwell and cesert thunder right by us and if i know bowhay hell wana show off his truck at both
