What motor is that? Are the mounting points the same as the LT4?
Interesting. I don't know shit about domestic motors. Just like the fact that the LT4 has that instant torque from the sc and that it makes 650/650 in stock form. Fluid changes are all the maintenance it would need and it would have stock reliability.
Lot of stock bottom end LS engines out there making ovet 1000 HP. LT4 is way too overpriced for the numbers. You could get a used HCI LS7 if you wanted to spend less and make those numbers NA
Iron block is actually cheaper. There are 5.3 aluminum and iron blocks available. The bore is the tricky part when pushing boost into an aluminum block. The aluminum L33 5.3 has a 3.78” bore so there is a lot more meat between cylinder walls to prevent any cracking vs something like a 6.2 LS3 with a 4.065” bore. Not as big of a deal with something like an all motor 427 with a 4.125” bore. But when you start boosting the engine with a turbo and a much harder torque hit the thin cylinder walls can cause some problems. The stock bottom end L33 is notorious for being able to hold over 1000 HP. With a forged rotating assembly the block itself can get closer to 1300 without new sleeves.
Go LS and do a build thread on it. I'm about to put my oem turbos back on and sell my motiv kit to start heading in the LS/LT direction. As an individual/consumer, why try to blaze a trail when you can taken a proven path for cheaper.
Putting the motor in the car is a new thing, but that motor is fully sorted. That is more of what I mean. And getting away from all the short comings of the N54 are a huge bonus. That's why I like the LT4. Sure it's costly right now, but it's a lot of power and 100% oem and untuned at those power levels.
