Having tuned a few of them, I'd also stay away from the LS3/480. The gap in power over the 430 is less than the ratings suggest. As Andrew says, get a 430 and put in an aftermarket cam suited to your preferences.

Although the Holley setup is nice, the factory style crate motor ECU can also work very well if you have a tuner familiar with it. The out-of-the box crate motor tune is usually off though (too rich) so tuning is almost a must.
