Hey guys, iv got a stock l31 with an lt1 can, open diff 3.42 and stock 700r4. Here recently iv picked up a 2800, stall converter, a b&m shift improver kit, a b&m trans cooler, and next week I'm getting a 3.73 posi rear end with disk. Will I have any noticeable difference with the newer rear end and stall versus now? I'm also looking into an lt4 hot cam but will be doing these upgrades first

 

Absolutely you will.

Going from 3.42 to 3.73 won't make a HUGE difference, but you'll feel it, and the car being able to hook up will definitely improve the seat-of-the-pants feel on take-off. The posi will make most of the difference.

Stock F-body tranny's shift annoyingly soft, so I think you'll really like the shift kit. And even a stock motor could use a little bit of stall, on yours that'll take some tenths of your 1/4 time.

 

I'm looking into a corvette servo aswell since the trans will be dropped out.
