Ls7
 

My vote is with Tony and John ... If I were to do it all over again I'd likely choose to save a little money and built a sick NA LS7 rather than the very pricey supercharged LS7 I now currently have.

But then again, the smile you get from 800 hp is priceless

If the car will see a lot of track time I would go LS7 and keep the dry sump or better yet go to an external dry sump pump. Managing the heat soak on a blown engine is very difficult to do for a car that sees 20-30 minute track sessions. The innercoolers are generally not efficient and there's very few electric pumps available to flow enough water to cool the intake charge well enough. If the LS7 heads scare you (I've never had a problem) then you can always use the LS3 heads on the LS7 block. If you want to keep the LS7 heads have the concentricity of the guide to the seats checked and set the springs up properly and you'll be fine.

I guess I'l just keep collecting LS7 parts as I have been and go from there. See what kinda deals I can find on Corvette forum with parts.

Guys are always getting rid of ls7 parts on ls1tech.

I'd go LS7 with upgraded parts. Yes, the liners tend to crack (so I've heard from several sources). I think you'll be happier with the extra cubes.

I for sure love the LS7, I've worked on a lot of C6Z's and my 2015 z/28 had it. Always a blast to drive.
