Doing an LS7 engine swap. With a reasonably stealth exhaust, talk about a "SLEEPER" :bubbrubb:

I think you'd be better off getting the L76 heads ported, add a higher lift cam, add an intake/exhaust and a tune.

LS2 guys are getting 450+ hp to the wheels with intake/heads/cam/exhaust

plus ls7's are like $13k

Seem's like an awesome wife :thumbsup: be sure to hold onto her. The L98/L76 that will come in the G8 is a pretty potent motor in itself, with a Cam, Intake piping, exhaust-straight pipes-headers and tune I can assure you that 500WHP is possible.

Unless you really want an LS7 I see no point.

LOL...I agree with you guys. I was just blown away that she came out with the idea. She's been spending way too much time hangin' with the Tampa GTO group....lol

Hey if you can afford it gramps, i'm all for it lol

QFT:pimp: :popcorn2:

Not a bad idea if you have the money. I'll agree with the L76 mods .. simple bolt ons to exceed 450+ HP on the GT is more then enough for most people... or so I'd hope lol

mmm I can't wait...

Sounds like a great wife, but an LS7 swap isn’t like a simple yanking of your LSx motor, and installing the LS7. Aside from cost, the LS7 uses a dry sump oiling setup, which would then require you to convert back to a wet sump pickup and pan. Elcetronics. The PCM, Harness, and Sensors aren’t simple plug and play with what you’ve got. You’d have to convert to a ZO6 or new CTS-V harness, then go from there getting everything to work. Let’s not even mention the cost of that.

You’re really better off as previously mentioned, doing a set of heads, cam, and even a blower that are much easier to do and more readily available in the LSx aftermarket world.

heads, cam and forced induction if you want to wake it up at a reasonable price.
