Thank you for replying back with such good info SS2win. I'm swapping a '99 454 into a '70 C10. The 454 is currently in a running/driving burb, and I think the best plan of attack is to do the 0411 swap in the burb, work out any kinks that come up from the ECM swap, and then mod the harness for the C10 swap. I'll report back how it goes.
-
I'm glad the information is useful to you. The 411 swap is really the best mod you can do. My tune should get it going pretty smooth to start with. I have over run around 30k on it now without issue. Let me know how it goes for you and if you need any help.

SS2Win, are you running the stock torque converter for your 4L80E (I'm just curious)...?
-
I don't think so but it was work done by the PO so I am not 100% sure. Why do you ask?
-
I'm wondering what it stalls at, and if you made any tune adjustments for this, just curious :)
-
Come to think of it, I used a base tune that may have had some mods to the trans. I didn't like the way it worked and so I found a stock silverado tune and did a segment swap. Don' think I uploaded that here yet. Do you see something in the tune?
-
No, I'm just curious, I just like to know/learn. :)

And here I was hoping you could tell me something about it. lol cheers
Here's the last one I will post. This includes the trans seg swap with a 2002 6.0 silverado. It fixes some problems with the trans that I never bothered to track down as it was easier to start over. While this tune has worked very well for me, your mileage may vary. I would like feedback if you have any comments. Otherwise, I hope it helps.

If driveability is good, don't mess with it, unless absolute necessary.
I'll look at that tune later tonite.
