very nice gain on that

 

good info

 

I added LS7 manifolds/cats and a custom 3" Dr Gas midpipe to my 08 LS3 corvette.

I also had Patrick G spec a cam (218/230 115lsa) and installed .040 cometic head gaskets, Yella Terra rockers and an ATI underdrive (10%) balancer.

Here's the dyno, car runs great. Ran a 12.08 @ 121 mph 2 days ago

 

Does anybody have a part # for the LS7 exhaust manifolds?
