LT4 fuel system and Alky/meth kit is a popular setup.

Since someone else bumped this thread and my car is gone. Let's say even Callaway couldn't keep my LT1 from breaking ring lands. They did honor their warranty though

It was my understanding the blocks were the same... Maybe someone else was confusing LS3 with LSA (LSA having piston oil squirters). All LT-V8s, if I recall, come with piston squirters and 12mm headbolts, which are some of the differences in blocks from the Gen IV days. LSA/LS9 blocks were also a different alloy.

Callaway isn't a great example. Look at the Callaway Camaro CSP had to fix for a customer.

700 wheel is about it with a oem lt. Keep in mind a blower puts more stress on the engine than a turbo/nitrous. The amount of power it takes to spin blowers pulls from the overall output

Oh it definitely underperformed, but I didn't see the Callaway that CSP fixed. Did that engine let go too? or CSP just actually tuned the thing properly and it picked up a bunch of power and reliability?

I had an LT4 fuel system on order from Summit and was going to send mine to CSP for tuning, but I sold it and went C6Z instead.

Retune and picked up a bunch of power. I almost bought a C6Z before a 6th gen. I had found a black 2007 with 7k miles. I couldn't reach an agreement with the dealer on fixing the heads as a preventative.

I need to find that CSP youtube episode to watch. You aren't going to get any dealer to fix the heads, that's on you after purchase or find one already fixed. Even the brand new crate engines that GM is still producing aren't fixed.

These forums are awesome and full of knowledgeable people but you will get a wide variety of answers because everyone's experience is typically limited to there own car or friends car.

I have been supercharging the LT1 since 2014 hundreds of cars across the globe with every different supercharger on the market including a few turbo systems.

There is no boost number or HP number anyone can definitively say is the limit.

I have been very good at doing a lot with a little via careful design parameters when building a project.

It is really all about what you are willing to spend, how you will use the car, what fuel you will burn.

Octane will be your biggest Limiter of power on any combination.

Lets face it everyone wants 1000 RWHP on 93 octane and a 10 K budget.

Then realty sets in when the engine fails.

I have done a host of Stock Long Block LT1 at 750 RWHP on E-60 fuel and they have run and run and run for many years now.

So the fuel, Cam, Blower, Exhaust, intake, tuning, fuel system, are all part of the package.

Well said, I set my limits but couldn't stay within that limit. I made over 770 on the stock short block and at over 17 psi it just didn't like it. We pushed every button and finally started pushing seals out and then the big bang theory became a factor. Even with number 1 and 8 broken it still had enough power to run a 10.13, yes it was smoking and it was oiling the track down but the belly pan/diaper saved my ass for sure. Slicks and oil are a bad combo plus the track clean up guys just don't like it either, but it was a short clean up because of the diaper. Pick your medicine but be prepared to fix it if you over play your hand or wallet.

I know that...still didn't want to spend 38k on a car and have to pull it apart to fix the heads.

Mine amazingly still ran well when I broke ring lands and pushed out the front seal. It happened at Mid-Ohio and I drove it 4 hours home from there.

Totally understand that, it sucks that the LS7 is so flawed.

I'm still trying to figure out why they(I think RPM) couldn't make a 103mm tb fit on it with some type of a machined adapter or spacer to get them the clearance needed. They gave up easy if there was really more power there.
