Im already nearing 7K and I havent gotten everything I need for my motor and trans swap, so I may need to put off the converter. Im not putting crap on credit cards.
I cant answer the question about the converter because I have never installed one o either of the 2 trans.

BTW, did you go with the stock 2.48 first or an optional 2.75?

I don't think that 2.78 is ready for the LS1 4l80e just yet. I'll have check with Chuck at FLT, I know the last time I checked he said it was being worked on.

But the shift recovery is SOOOOO much better with the 80e that it has been said makes up for it. I will have one soon in my truck if at all possible Im going to try and put the truck on the dyno before the swap to see how much we truely lose by going to an 80e at the wheels. I would bet my truck its no more than 15-20hp.

I feel the same way bro. My trucks feels much more sluggish at low speeds and taking off but once cruising or on the freeway its great.
I went with a 10.5" converter and I'm not sure of the stall anymore since it was made for N/A but at the HP levels I'm at now. There is no way in hell I can hammer it from a dead stop though. LOL
