After reading the boards about the power curve on the stock L98 350 TPI,
I changed my mind & did not change to 3.73 gears.
Instead I changed my stock 3.23 rear gears to the 3.42 's

Not much difference but it feels a little stronger.
My best 1/4 mile pass at Kansas City International Raceway yesterday 6/30/06
was 13.952 sec @ 97.90 mph,
with 29% humidity & 87.4* temps

I'll post again in the fall when the temps are more favorable & see if I can't beat my best of 13.85 @ 98.06

Here's an updated list of mods made to my 1991 B4C which has a
