ls7/lsa/stroked ls3/other?

[DavidBoren]

I was thinking that you could probably get a LSA pull-out from a CTS-V for cheaper than any of the other options. And that gives you the oem supercharger right off the bat.

If you are buying new, or have the budget to buy new, then I would go with a stroked LS3. If you can achieve your power goals with a naturally aspirated engine, you should probably do that.

Stock LSA will put 570 to the ground with a factory Gm performance parts tuned ECU.
