Predict my E.T ....

Convertor...........needs at least 4500 stall.
340'S run better with gear and stall.

12 seconds on juice....13 seconds on motor.

With convertor....12 seconds on motor and high 11 seconds on juice.

That's a really big tire for 3.91's.
I believe it's a 30 inch tall tire.

That's like running a 28 inch tall tire with 3.23's.(2800 stall)

It's 60 foot will be very slow.
