Need help with cam and stall
You're absolutely going to want/need a converter with that cam. I once had a very similar cam but in a 5.7 and it was terrible to drive (would try to pull through the brakes at stop lights, etc.) until I put a proper size converter in shortly after.

Verdad Gallardo Not sure what you mean by loss, if it be 1/4 mile that would depend on the rest of the setup,etc. I've have had 2 auto LS's one had a 3600 and now the 4k...id take the 4k over it any day of the week. Like said I wouldn't go any lower then 3600 period.

Most cars that go 3200 stall under-perform more often than not. 3600-4000 seems to be the sweet spot for daily driving and max performance at the track.
I daily my Yank SS3600 w/ 3:73 gears and its amazing.

I have a CircleD 2E (loose and efficient NA converter) and have had both 3.23s and 3.73s with it. The 3.73s tigthen it up a good 300-500rpm with the same throttle input. So I can keep up with traffic at 2500 with 373s but it was 3000 with 323s.
If I went to a 4C (3600), I'd be around 2000 in traffic with the 373s (2500 with 323s) with the same throttle input. Of course, throttle input changes your accelerating RPM... once you get above your stall speed, the car accelerates like a bat out of hell. Below it, and it's slipping. So the bigger the converter and the less gear you have, the more it slips. Which means RPMs rise, trans temps rise, and overall sound goes up until you give it enough throttle to really move. The 2E drops 800RPMs between shifts... the 4C 1000. And both are 95% efficient or better on the top end. So they perform.
With the 5.3L... you cam it pretty much like you would a 346 with just a touch less overlap. But I would definitely go with a 3600/3.73 combo. I think it'd drive fine. Just make sure you exhaust isn't stupid loud. The higher stall amplifies it significantly.
I would do something like this:
LJMS Stage II Turbo Cam 226/231 .605"/.598" 113+4
This would be a good cam NA in a hot 5.3L when combined with a 3600/373 combo. It would have a lope at idle. And drive very nice.
And the plus? You can use it if you ever turbo the car. With a 5.3L... the car is almost begging for a 76mm turbo. And I'd run the 4C with the turbo car. So I'd just start with the 4C/373 combo and put the LJMS Stage II Turbo Cam in the car. It'd perform well now and later down the road if you wanted to change things up without buying things twice.

Appreciate all the input guys I think I've read enough now to help me with the build I been into cars for years but the more technical stuff I still need to learn more about when it comes to engine building and definitely anything to do with a transmission only question I got left is with a 3600-3800 stall what size cooler should I run
