Are we still talking about low end torque with small blocks?

Hasn’t been ruled out. Has to come into to same cost perimeters. Prefer to avoid the extra weight and drop in fuel mileageAre we still talking about low end torque with small blocks?

The ideal would a 6.2L from a Caddy SUV. That would be fun with all the 6.2L hate on CK5.
Those brothers have two different mothers.
Isn’t an LS3 a 6.2? Those bastards?
AL heads and manifold on a BBC drop somewhere around 100lbs. What weight are we talking about again?
That’s viable for weight and is only margay more expensive
A small valve AL head BBC would pull nice
There is nothing wrong with being slightly heavier.... {cough, cough}...
Late to the conversation here, but an LS swap is not all that expensive or complicated imo. Hell, I did it after all. 
Yes, you end up with an engine with 100k on it, but also one that was designed to do 200k+ easily. Plus, once properly tuned, it will run like a champ forever with little to no adjustment needed. No hassle EFI with off the shelf parts available at any parts store sounds pretty good to me.
Of course if you've got your heart set on a BBC, I'm not trying to talk you out of it, just saying that the downsides of the LS swap are pretty minimal imo.

8.1 FTW. Technically not an LS engine, but with the reliability of an LS engine, no need for conversion crap (can use stock motor mounts and headers off any old school BBC), will get you the low end tq desired but I bet the milage drop won't be noticed as much (what is your mpg's currently...can't imagine it's much higher than 14 at the max...the 8.1 will probably get 11 everywhere with how you will use that truck). Your current tranny will bolt up to it with no troubles whatsoever....shall I continue?
Sure! Everything still relative to total cost of course8.1 FTW.

And averaged 15.5 driving it to Moab last year. Even missing a gear
Yep program required due to the standard transmission. Which also adds new flywheel and bell housing.Late to the conversation here, but an LS swap is not all that expensive or complicated imo. Hell, I did it after all.

Program probably require a couple retunes I would suspect.
I think a 6.6 would be an easy/cheap swap.
I like stirring the pot.

I was just messing with ya, I know the 8.1 isn't for everyone. But I will say, when I hear people contemplating swapping a 6.0 into a square, I for sure tell them to go 8.1 instead and would be way more worth it (mainly for a lot of the things I already mentioned, plus 6.0's actually get less milage than what people think they will, so I would rather have the low end tq in a big square).
Aside from what I already mentioned, electronics is identical to LS's, and so is fueling. But in your case, just a new pump and possibly running some new lines (not sure what your fuel line situation is like currently) and fueling is done. Cooling would just be install a big block or 6.2 diesel radiator on there (I went 6.2 radiator and shroude, bolted right in) and that's done. It's about as straight forward as it gets really
I had @Team208Motorsports do my tuning when I had my nv4500 and it was no issue at all. When I switched transmissions to auto, he reprogrammed it for no additional cost. I didn't change my bellhousing either. I did buy a new flywheel though.
I probably would have gone 8.1 instead of 6.0 if one would have come along when I was looking, and I didn't have to deal with the fact that big blocks don't fit in 1st gens without some extra work. At the time I was worried about doing too many things at once. If I had it to do over again, probably would go 8.1.
Yeah but you're the guy building any entire house! That's like saying a 6.0L swap is as easy as building a house....Late to the conversation here, but an LS swap is not all that expensive or complicated imo. Hell, I did it after all.
Josh at @Team208Motorsports is the man! He's local to me and a real good guy and REALLY good at tuning. I recommend him to everyone I talk to about tuning
Yeah, looking at first gen's is a whole different deal when it comes to swaps. So I would understand going 5.3/6.0 in that case. When looking at 73-87/91 squares, it's WAY easier.
Yep I got some details mixed up on that bell housing. It’s good bouncing ideas. I’m actually going to spreadsheet costs before making any decisions
That will also include looking at dyno sheets for the engines applied to that spreadsheet. 6.6 not included @ktmoutfront
