once you understand your engine build and power adder specifics, talk with a converter manufacturer, recommend circle D, about your specific goals and motor/truck specifics, and see what they recommend for a torque converter... i think you'll find they'll recommend a 2500-2700 (at most) rpm stall assuming your going to run big boost on a low compression motor with aftermarket/regrind cams...
Yup... what Bubblehead said.
I believe you want to talk to Brian at Circle D.. he is a Raptor guy and knows our trucks pretty well.
Look at the drag race parts for the 6R800 if you think you will be makinging over 800 hp. Outside of Xedey HD clutch packs the trans doesnt need much.
I rebuilt mine with all the HD clutch stuff but at the time didnt know about the Circle D. Ran it hard for 4-5 years without issue and I was making 640hp (at the crank)
Thanks guys. I will check out Circle D. My goal is to get close to get at least 700hp at the crank and closer to 800hp at the crank. First recommendation I got was 3000 on the stall and I did think that was high. I had 2800 on a nitrous Mustamg Mach 1 and that was almost too high for daily driving. I'm not a collector, if I put money into it I will use it. The truck will see 50-60% daily driving.
