*the clutch slipped on the dyno* video link https://youtu.be/-bYzmGNH3NM @28sec
Did 568rwhp today, but the run was cut short cause the rpm signal was off. Gonna dyno next week and should be good for 580rwhp.
The hp is still climbing and should peak around 7400-7500.
I am satisfied with the results on 91oct.
FED heads are the goods; custom 262 TFS program.

Great results man! I love LS3's with a 239 intake lobe.
Yeah I was confident about FED program. Its one of their old design, they dont do it anymore. The extra ptv prevented me from having to notch the pistons, which was a big deal for me.
I see those intakes are custom made runner length for your combination. Do you tell him how long you want them or does he figure that out for you?
intake has me intrigued
You can pretty much tell him what you want for runner length and everything...tapered or not,height, etc. He takes his base design and can work something out for you.
Just blew the slave cyl seal. Now that it happened I realizedit slipped on the dyno and thats the dip at 7000. It slipped for a good second. I have it on video.
