What stall Torque converter?

[hemi43]

First thing is to change out those gears. 3.08:1 with 35s will be horrible at best. Camshaft selection will usually tell you what converter to use.
FYI, If you try and use a 2500 stall converter, you will overheat your transmission with that tire and gear ratio.
A vehicle is a combination of parts all designed to work together in harmony. You need to design everything as a package, which means you can`t buy a high stall converter now then decide a year from now to install higher ratio gears.

Edit;
I just did a quick calculation of your setup, and at 60 MPH your engine will be spinning 1875 RPM. At this speed, a 2500 stall converter would have in theory over 600 RPM of slippage which is too high. Also, if you have a cam designed to make power in the higher RPM range, your engine will be very inefficient. If you can tell us more about the engine ( cam specs, comp ratio, intake style, carb size, etc ) we may be able to help you a bit more.
