What stall Torque converter?

[ScottyTightdog]

71 Blazer and I Currently have about 400 hp 350 with granny 4spd and 3.08 gears on 35's. I'm swapping to a TH350 that I am currently rebuilding. I'd like to hear your thoughts on what stall torque converter I should get from people with Blazers and possibly a very similar combination. My plan down the road would be to go to 4.10 gears and maybe 37's as well. Thanks in advance.

Just finished a ‘72 GMC Truck with approximately 400hp and a TH350 with the same 308 gears. I have a 355 full roller with a Comp 282HR cam; went with a Hughes 2500 stall and it works great with my setup. It is very streatable, yet does what it is supposed to do. Hope this helps!

Thx, From my research I was leaning toward a 2200-2500 range.

I got a Comp cam and lifters and a 2600 stall I bought and ran maybe 500 miles then took the truck apart to build my 2wd blazer, changed the cam and lifters to a more streetable application and swapped to a 700R4 trans.
the stall fits a 350 turbo trans.

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.
