I assume it has modifications and a tune?
What’s done to it?
Replaced my 2012 ZL1 with a 2011 CTS-V sedan
Had my fun with the Camaro but wanted something a little more comfortable and suitable for my age.
Promptly grenaded the motor on the Caddy. Holes in both sides of the block and pieces through the Supercharger and even put a hole in the brick.
I'm currently removing the engine and learning what I can here to help whip it back into even better shape over the Canadian winter.

WHOA! That's some catastrophic damage! Do tell if you know root cause!

850 injectors
9.7, 2.55 pulleys edit 9.06 , 2.50
1 7/8 long tube headers 3" mids
I believe the premium fuel I got while travelling wasn't good and I got into it a little too much for the fuel.
My bad.
I'd like to put together something stronger with similar power that will last but keep it relatively simple. Maybe start with a LSX376B-15 and have the LSA blower rebuilt, unless there are better options. I'm in the early stages of learning about these beast. Hoping to keep the upgrade under $20k
That’s an unfortunate way to start a build , what part of Canada are you in ?

Man! You were on a roll until that part!Hoping to keep the upgrade under $20k
The B15 is a great pick IF you were gonna leave it stock for warranty… but you already stated your plan is to mod the blower and more.
IMHO you be way better off to grab an LSX or similar and scratch build because the B15 you’d end up forging the bottom anyway.

I thought that engine already had a forged bottom end. From Chevrolet - "The LSX376-B15 is durable, and its all-forged rotating assembly supports up to 15 pounds of boost. The engine is topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations."The B15 is a great pick IF you were gonna leave it stock for warranty… but you already stated your plan is to mod the blower and more.

My concern for the OP would be the amount of boost. The pulley combo from the old engine would be around 17 pounds of boost depending on cam and other mods. Are you stopping there or considering using the current mods as a starting point. Researching a trip to Windsor I read that regular premium is 91 octane in Canada, although they have a super premium gas with 94 octane. I'm only about 60 miles from the Southern Ontario border and was thinking about a trip up now that the border is open. Since I'm tuned for 93 I would need super premium. What gas is available in Northern Ontario?
I will happily defer to higher authority(!) But I seem to recall that the B15 had the same ‘forged powdered steel ’ cracked cap rods as the LSA.I thought that engine already had a forged bottom end.

I did verify it’s true that they have the LSA units; while the LSA rods ARE technically “forged”, they are generally considered not equal to ‘solid’ steel forged rods. Doesn’t mean they can’t do the job, but they are typically not retained when bigger builds are assembled.
I'm sure you meant 9.17/2.55 right?dual HX

By the sounds of it, probably best to say hadI assume it has modifications and a tune?

In the North we only get 91 and I question how long it's been sitting in the tanks of some stations due to low volume. I believe the 89 may be better at some stations. I have a powersports shop and know first hand how the shelf life of fuel isn't what it used to be.My concern for the OP would be the amount of boost.

93 is definitely available in the more populated in the south (Sunoco has some good gas)
From what I've learned on this forum the setup in this car may be marginal for 91 and the boost may be a little on the high side (depending on the tune I suppose)I'm sure you meant 9.17/2.55 right?
I'm just going by what I was told by the previous owner on pulley size but once I get the motor out I'll double check the pulley size. I may have to reduce it a bit? If the new motor flows a little more boost could go down though right?
Optimally I would like to be able to run it on 91 and maybe add something like Klotz hitrate when I want to flog it a bit.
Meth injection may be an option to keep det away also?
There is also a flex fuel sensor on the car but we don't get ethanol fuels here.
Much appreciated for all the input and info I've learned so far here.
I'd lay money down that previous owner pushed it to the edge and you just pushed it the rest of the way.
I thought in a previous thread, the B15 was a good option while being at 376, versus moving up to 388-396 or up the Dart was better.

Possibly you are correct. That is in the past now though, it is what it is and there were some things learned, which is positive.I'd lay money down that previous owner pushed it to the edge and you just pushed it the rest of the way.

There is no replacement for displacement! More cubes aren't off the table. It all comes down to not getting carried away with cost and creating something with longevity and daily drivability.

WE NEED PITCHAS!
I have a true need to see what it looks like to dismantle an LSA so violently that the BRICK is punctured.
I have the same attitude, the past is the past.Possibly you are correct. That is in the past now though, it is what it is and there were some things learned, which is positive.

Read threads where @Rubber Duck and @Lt1z comments on people thinking about different combos....two of the deepest wellsprings of information.
LOL. I hear ya. No worries. They'll come. I only have an hour here and there to get this motor out so it'll be a slow process. I'm almost half way there. Until then all I have is one shot and the trail of coolant and oil it left. She's got a good coat of undercoating now anyway lol.Speaking for the group:

I found pieces of thinner aluminum (oil pan) on the road as well as thicker roughly cast chunks (I assume block)
It dumped pretty much all the oil and coolant.
BRUTAL! took out the Level indicator! never trusted those damned things...
Wow.
I’m liking your positive additive, and developing a plan to rebuild her.
