Ya but you can drop it in a Rail on Friday and be running 8's by Saturday.........

And that motor makes more HP than the new ZR1 corvettes and they have a blower and all the fancy electronics shit.........

Beeen drinking all day again? I hope Obama pays you to wave his banner.

I don't know why you'd go to all the trouble of buying a new 13:1 250* cammed 454 LSx when a 4.8 will double that horsepower.

heheheeee
