Good on ya for building your car how you want your car to be built. I have friends running lsx engines and they make great power and love power adders.

I am a dodge guy but can not deny the lsx is a good engine. Good luck with the project and have fun with it, I am sure its going to leave a lot of cars seeing tail lights. The car is very clean looking and will turn a lot of heads.
