we would have to see exactly which parts would be left in or not. The tilton 3 Disc Carbon clutch alone is $6200.
Heads are $3200
rotating assembly, machine work, etc.

Give us a call and we can get you a number.

Question would be if there is much street driving. either way, we can get the proper package for you. (street driving would use 7 octane less.

Does the car have a 30 spline output shaft? The ZR1 diff isnt a direct bolt on if not, requiring a transmission surgery.

Are the heads with a core fee or does the $3200 include new castings?

Or a Z06 Transmission. Transplant, not surgery

The ZR1 diff has the larger ring gear and really strong side covers.

There is a core fee or your heads are required.

THe LS3 heads are pretty good to begin with. But there is always something to be found.

Stock LS3 6.2 liter which is 378 cu in stock.

The LS3 heads start out with a great port also. Then adding the CnC porting and other work plus our Cam and Fast 102 puts it over the top.

Thanks
