Yea, it was the very first mod I did. Even before my Air-Raid MIT, and true-flo filter.
I'll admit, it was much more fun when I had 4.10s. Its harder to tell any difference with the 3.23.
I had 3.42 and G80, 4.10 and tru-track, and now run with 3.23 and tru-track. Loads up the turbo very well... But before the turbo I ran all three ways NA.

The reason I ask is my truck also has 3.23s and a stock converter. I know how much steep gears and a good converter can help performance. I actually like the fuel economy that my truck gets. I'd like for it to get better instead of worse. Gears would hurt mileage everywhere, and a converter would hurt it around town. A cam swap could actually help fuel economy IF it is conservative enough.
I'd rather swap to a 6L80 (to get a MUCH steeper 1st and 2nd gear) than swap gears and converter. But that is a long ways out.

With 3.42's and 3.23's, any loss of low end is amplified. I can't say that I lost any with this cam.
Here's my deal, I got a tune and thats when my mileage took a turn for the worse. I got the cam after and it stayed the same.
I know a lot more about tuning now. The quest for mileage is one of the reasons I am going back NA. I feel like I will be able to get my original mileage. I doubt it would get better though...
NA and 4.10 mileage = turbo and 3.23 mileage
I wish the 6l80e electronics were figured out. I would love to have that unit.

OP, I have that same cam in my truck. I'm using late version 918 springs. No problems at all. It pulls pretty good.
However, I can't really provide low end comparisons to your truck due to the mods on mine.

I am guessing since this cam is so mild it would be OK with stock TC and stock manifolds. I understand it would make more power with aftermarket but I was thinking something that would help the truck get out of the hole. Maybe a torque converter would suit my needs better. I could have the tranny built and TC put in before the LS2 goes in.
