2.73 to3.73 ?

So I ran a 12.44 @112 with the stock gears and want to know what I would expect from 3.73. I no I no stall it. But I can get a free rear end with 3.73 so why not right?

I went the same route from 2:73 to 3:73 and it was awsome. I never raced it but you will feel the change threw 2nd gear in an automatic. Best bang for my buck so far.

I think I picked up .3 or so....maybe ?? been a long time ago now.

The better ET will come from a better 60'.

When I went from 2:73 to 3:73 in my Lt1 T/A I picked up 3 tenths consistently in the 1/4. Its definitely worth changing! The car will rip thru the gears compared to before.
