That said...that LT1 is freaking awesome.
As Gretchen said earlier...420HP 430 TQ is not pushing it in the LF3. Hell, it can go well past that easily. We see it all the time with forced induction on the LFX which is a fairly tough engine, but has a couple weak points you have to watch out for once you start climbing near the 500 bhp range. The LF3 is stronger so I'm sure it could handle 500 without much issue.

An engines ability to handle a certain amount of power vs. what the OEM will ship it with are not the same. The OEM works with a factor of safety to minimize warranty costs. The fact is, all else being equal, power is related to the pressure developed in the combustion chamber. The more displacement, the less pressure is required to produce a certain amount of power. Higher pressure leads to higher loads throughout the engine and particularly on the rings. For a 3.6L engine to produce the same amount of power (at the same rpm) as a 6.2L engine, the average cylinder pressure needs to be doubled. I want the engine that is only working half as hard.
