Engine
 

LS7 dry sump came from a donor C6 Z06 with 4K miles, a service manager at a Chevy dealer acquired the engine for a build that wasn't happening, so I purchased it from him

I liked what Katech has to offer for the LS7, plenty of R & D verifing their cam and valve spring combinations as well as diagnose valve train issues using a spintron. So I pulled the heads and sent them to Katech for their "LS7 fix" including porting, bronze valve guides, Ti/Mo intake valves and new LS7 exhaust valves, and PSI springs set for their Torquer cam among other items

The Block was bored .005 and honed, bearing alignments checked etc.

We used a set of Mahle power pack pistons, balanced the rotating assembly, replaced the lifters, all bearings and bolts

Hand filed the rings, HD timing chain, new oil pump. The bottom end is stock GM except the Mahle pistons.

Bump Stick
 

Based on Katech's torquer cams I had Comp cams grind a cam with 114 LSA. I felt the 110 torquer was a little too aggressive and Katech's 116 LSA not enough

Head Assembly
 

Final head assembly with installation of a CHE trunnion set

Nice parts. :thankyou:

That is going to be a bad ass motor
