403 Stroker Kene Bell
Hey guys I am working on my new build. I recently broke a ringland in my stock LS6. I already had a 403 from a previous build setting around. So I decided to use it. It is a iron block which I didn't really want to use in my Z but decided to try it since I already had it. For heads the motor has ET Performance 255 11 degree heads. The compression is lower than I would like 8.5 to 1. My Kene Bell is a 2.8 from Jeff@TPE. I am looking to make 800rwh and TQ and to run 9's in the 1/4. I already have the motor out of the car and the new one ready to go in. I am putting the new one in this weekend. I am hopeing to have it in and tuned in the next few weeks. I have some pics for all you guys enjoy.

I just want to see the diff in air flow between the 2.6 and the 2.8.
8.5 CR seems really really low for the KB though. I had 9:1 and my 2.6 just couldn't make up for it. I ran it at 20# and it took so much HP to turn the blower that it wasn't worth it. I was only in the low 600 to the wheels at 20# with the 2.6 on a forged 346. I backed down to 16# and picked up 35HP to the wheels. Now there could have been motor issues or INTAKE ISSUES (cough, Jeff, cough, intake,cough).
With a solid motor, NEW INTAKE, and around 14 to 16# I hope to make atleast 775rwhp. If not there will be a 2.6 KB for sale really soon.

Awesome...I followed your thread when you installed the Kenne Bell. I will be tuning in to this one as well.
I am planning to do the same as you, only with a LS2 block at 402 cu in. 9.0:1 compression, tfs 245 heads, and a 230/238 cam under .6 lift on a 114+2.
Good luck with the build and keep us informed!

Thanks Bret. I am hopping to make that everthing goes smooth. I have pulleys up to 21psi but I am not for sure if that pulley will make that much boost with my heads that flow crazy amount of air. If I am not mistaken they flow 350cfm @ 600 lift. The cam I have is 630 lift so I guess we will know shortly. I mostly drag race so I am anxious to see how well this system works. Seeing how I am one of the few on here that drag races. I am really interested to see how well the 3.90 gears work with this setup. I had a bad bog with stock motor after launch due to tune and 28" tires. I could probally get away with not even running meth this low of compression but I already have it so I will anyway.

Dang, I feel like the low man on the totem-pole with my little 2.6, haha. I am hoping my car is on the street by February. We are putting it on an engine dyno before installing it so we can make sure its spot on before it goes in the car. Sounds like there will be a few 403 Kenne Bells in the near future.
