I definitely want something that I’m not going to have to work on all of the time and can be good at idle. So my best bet would be to look into a LS2 or LS3 and adding a turbo. I’m sure the turbo is more expensive to build but easier to get the results I’m after. Do turbos effect daily driving at all when you’re talking about that hp range?
Actually, No, Your best bet is to stay away from an LS2 or LS3.
Why? Because they are expensive.
Turbocharging is a great option. For your HP level you could use the factory cam and have a nice idle and fuel economy....that is until you hit the go pedal
I nice used 5.3 or 6.0 truck motor (steel block LM7 or LY6) would be a good choice for a turbo application. Find one that is 2004 or newer if possible. Early versions are fine but have weaker bottom ends. One of of the biggest challenges with turbo is fabricating the hot side plumbing. If AC is important to you that could also be an issue to package. There are truck kits available but I am waiting for Holley to offer a hot side kit for G bodies (Todd are you listening?)
