How do you pick a stall speed?

[GregP]

For new car, never run so no prior baselines. How to make a first guess.

Wt ~ 2800#
Gear = 4.86:1
Tires = 29.5 x 15.50
HP ~ 550 @ 6000
TQ ~ 560 @ 4500

Not enough info.

In order to accurately pin down the best converter for your needs, much more information is required. Instead of retyping everything, take a look at the application chart that we utilize at TCI.

Ok, more info

Front and mid motor plate mounts (mid is 0.090 steel)

Car:

stretched wheelbase
4-link rear
Fab 9 w/ locker 4.86:1 35 spline axles

I plan to discuss selection with the trans vendor(s), but always like to know as much as I can going in to help in asking the right questions (and filtering any BS if some happens along).

We would recomend.....

about a 3200-3500 stall depending on a few variables like how streetable you wanna keep it, but you can easily run these numbers with what you have. I would also recomend keeping it a lock up. Check out what we would have to offer.

Thanks for the reply. It seems that most people I've talked to are in the same area, around 3500 stall. I want the car to be able to cruise with the local Corvette club, and of course make the long idle down the boardwalk in Ocean City once a year. It will be raced at the all Corvette drags a couple times a year. The rest of the time it's just for fun runs on a nice sunny day.

Thanks - Greg
