Default 3.23 to 3.73

I was thinking of going with 3.73s in my car. Could anyone provide some before/after 1/4 times if they did this?

Would 3.73 make lose mph or would it help?

Almost everyone gets the following results:

with a high stall converter:
.1 & 1 mph

with a stock converter:
.2 & 2 mph

Sometimes people see higher gains, but most of the extra gain came from improving their shift points (done when they got their speedo corrected).

Is it worth it to adjust the shift points with a stall? How about increasing shift firmness? My car shifts really slow after converter install.

Shift point adjustment is needed only if they are messed up (sometimes they shift low from the factory) or you want to shift at 6200 or higher for better performance (depends upon your mods).

Shift kits are nice but not necessary. If you firm shifts electronically, do not overdue it or you can damage the tranny.
