Thank you!

Update as of today: The LS9 Block and GMPP LS9 CNC Assembled Heads have arrived. Next on the list of priorities is getting our Katech Competition Valve Job, CC'ing the chambers, determining how much need to be decked to achieve my target chamber volume goals, and actually decking the heads. Afterwards they will be ready for assembly.

The shortblock will begin assembly slowly but surely as well. Pictures to come

Update 5/31: LS9 Block is blueprinted for assembly, 4.065 pistons should drop in just fine. GMPP CNC LS9 Heads have arrived, they are now inspected and disassembled. Off to CNC they go for additional Katech Porting followed by our Competition Valve Job + Blend.

Katech_Zach · 05-31-2019, 08:02 AM

Disassembled Heads. Note: This is the OEM GMPP CNC Port Job shown. Very good quality from GM, but flow will improve even more while maintaining high port velocity with the Katech developed port.

Update 6/4/2019:

Clutch and flywheel look like they have served their life at 52k miles. No damage, probably could be used for awhile longer but I will be replacing it while its out.

Katech LS9x Clutch and Billet Aluminum flywheel will be going in.

Interesting data for you guys:

The core set of heads that I chose to use for my build were factory GMPP CNC LS9 heads. I chose to CNC port these heads using our Katech port to see what would clean up (if any at all). We blue'd the cylinder ports and ran the program. The result showed that the Katech port not only has a better surface finish than the GMPP cylinder heads, but it also cleaned up nearly 80% of the GM CNC'd ports.

The Katech ports are larger, and have a better surface finish.

Note: This is not the final product, the heads still need to be decked, valve jobbed, and blended.

Awesome thread! Totally following because I <3 the LS9. Your mod choices are fantastic.

JakeRobb · 06-04-2019, 02:31 PM

Man, that port job looks amazing.

hrpiii · 06-05-2019, 08:43 AM

wow!! great work.

Zach,

I have a lot of the same suspension mods as you except the Bilstiens and Im running DSE rear control arms.

I have long tubes installed with a Z28 NPP without resonators and a Corvette X Pipe (king of re-purposing factory parts) sounds awesome.

I'm slowly buying my parts for a cam change. Will be following your build from India (new job assignment).

An when I can I run NCM in Bowling Green.

Great choices, the DSE arms are a nice piece as well. I am also considering switching to an X-Pipe, but we will see.

An update for my build: The Fel-Pro head gaskets, Callies Crankshaft, and Callies rods have been ordered. The pistons have been measured, weighed, and organized based on my block measurements.

The headers are on there way, I am very anxious to see the quality of the Grams Performance headers.

I will be sending my intake manifold out soon to be ported and modified by the great guys at GPI. Paired with the stepped headers, these should really work well with the Katech ported LS9 heads.

Zachary,

Are you running high pressure or high volume for your oil pump?

I will be running the Katech CNC high volume pump for my build. Since I will be using piston squirters, I will need the increased volume. If I did not have piston squirters, the standard volume variation is more than enough.

Katech_Zach · 06-14-2019, 11:03 AM

Small update, the block has been clearanced for the 4" stroke. I will begin assembling the heads today. I made an update to the rotating assembly, so I am now waiting on a different set of rods and a crank. I chose to go with a crank and rod combination that utilized a 2.000" rod journal instead of the standard 2.100".
