Low lash solid roller LS3 sbe, 667hp on the dashlogic
I finished my build with some electrical hiccups at the end (loose ground).
it goes like this;
-FED old version of custom 255 TFS bare cast (now 262cc) with hollow valves and PAC 1209x with FED Ti retainers. Mostly assembled by me. GM head bolts. .040 Cometic. 11.33 CR.
-T&D adj shaft mount rockers 1.8..makes nice lift
- Cam motion LLSR 239/253 720' 702' 112lsa donated by a certain guy named Hammer. Degrees.
-Isky red zone linked solid lifters at a very friendly price from a guy named Ws6TA
-Meziere EWP with shortbelt mod
-LSA injectors
-stock valve covers with baffles removed with a 0.5inch ICT spacer
-Taylor wires to clear headers flanges and TR6s
-Goertz1 custom int manifold made to clear stock hood & BBK 102mm & Holley fuel rails
-6.75" 3/8 PRs from Smith Brothers
-Fluid damper 25%
-Melling hi press
-2inch SW headers/HFC into stock NPP/H pipe
-18lbs Mini spec clutch/flywheeflywheel
-Pat G remote tune, 91 OCT.
It pulls so smooth up top...nothing like my old HYD setup which was hanging at best after 6800. I can feel a good power bump and the powerband is so much broader. The car has very good torque right from 3500, it feels stronger than my last smaller hydrolic setup. Limiter at 7600. Going for 7900-8000.
I do have a Dashlogic that did show 667hp today. 480+TQ iirc.
Cam only the Dashlogic showed 590hp and it was really dead on compared to dyno and track.
Valvetrain is quiet and sounds great IMO. I set it up with some preload in it so it's quieter at idle. 0 lash cold and .010 hot. Llsr cam card says 0 cold.
What you think?
I wanna hit 675 fully tuned, 570rwhp+ on my friends dyno. 700hp on 91 might be possible with better exhaust, crank scraper and a front OTR CAI. Next year...

Congratulations, Great Results!
More info & Photos of the Intake please.
What chassis and PCM year are you using?
How is driveability 1500-2500 RPM?
Where is idle and what is rest of Combo and useage.
Who did your tune?

The car is dirty as hell, still too cold to use the water hose outside...
Stock pcm, 2013 SS 1LE, drivability is surprisingly good, as good as the last hydrolic setup. The surge is from 1800-2200. It's worst because of the clutch. Car drives real good doesn't feel like a big donkey cam.
Built it this winter, learned all that by myself, with the precious help of other members, thanks to Lazer, Hio, Hammer and the Trans am guy(my official parts Warehouse guy!), zack, Jaik...they were very patient with me, beeing a total noob haha.
Pat Guerra is working on my tune right now. He is a busy man, but his tunes are just sooo good. I'd like to learn to tune but I already paid Pat G and the Autocal programmer, so I'd be dumb to pass on that. Next project I'll tune it.
Car is a blast, but the gears are way wrong; this thing will pull to 130mph in 3rd LoL. Stock rear/ trans (Lazer told me but I want all the power 1st!). 4th is unusable on the streets cause you are going way too fast already!
This LS3 revs beautifully, it's addictive...

The car lost some oil pressure, as I expected it; from 49 idle to 40ish. Looks alright to me!
