4L80E stall

I'm planning a 6.0/4L80E swap in the future for my '71 K20. The 6.0 (most likely LQ4 unless I can find a deal on a LQ9) will have a cam (TSP 224R or 228R), long tubes, and a tune. I know the 4L80E has a relatively low stall speed, so with the mods mentioned above, will I need to go higher? I'm thinking I will have to, as this is going into a 5000 lb truck after all. I don't really want to spend the money seeing as 4L80 converters are brutally expensive, but I'd rather do it before the swap happens rather than find out the engine is a dog afterwards.

So, if I do have to change it, what would be a recommended stall?

Thanks!

I'm looking at Revmax converters on Fleabay, and some of them say not to be used in trucks. Why is this? Too much weight?

Give me a call and I can help. We have several different converters that will fit the bill for your setup.

Circle D==FTI==Yank. Read reviews on the web and make a decision. I have read some good things about Revmax but have no experience myself. I have run a couple of CircleDs with no complaints at all.
