Hello, I am a complete noob when it comes to cars so please please dont bite my head off. I drive a 2003 Pontiac Grand Am, 3.4L v6, and I was wondering what v8 could I put in the car?

Forget it! Much to large to fit, too complicated to install and the transmission won't even think of handling all that power. If you want some power put in a 3.8SC with the 4t65E tranny. You will need the proper PCM and fuel pump to make it work and probably a custom exhaust but it has been done before.

Yes or just add a supercharger, I kmnow www.RSMRacing.com has kits. they run on stock internals too so you wont have to worry about blowing up your motor
