But...your information says you're in San Diego. How are you going to get the engine to pass the new, CVN verification part of the CA Smog Check? I ask because I have a less aggressive LS7 build which I'm trying to get to pass the Smog Check. Maybe whatever you're going to do, or are doing along those lines can help me, too.

I found pictures and edited the blog for a more chronological transformation. I have had a lot of issues with this thing and just wanted to make this as detailed and correct as possible
here are links to other posts on the head issues i have made.
Parts arrived!!! Waiting on one last tool Installed oil pump (loosely) Removed flywheel Lubed up the bottom end Crankshaft oil deflector Torqued to spec Covered up for next weekend.
From one 07 velocity yellow to another ..Good luck with that build ..I bought mine totally done ..I’m retired..I couldn’t imagine even attempting what you are doing ....Good luck with everything....

[QUOTE=REDZED2;1604970928]Comp cam???? YIKES!! Lobes? Those specs make no sense. .612 lift? What rocker ratio. Otherwise BRAVO! PICS AND ALL FINE SIR. GREAT LOOKING JOB![/QUOTEyx]
Yesir Comp Cams,
Yella Terra Ultra lite 1.8:1 roller rocker;
Jayyyw nailed the lift @ .648" compared to my last cam .635".
( TSP 2.2 was 112.5 lsa .635" with 1.8:1 rocker ratio; had 15 degrees of overlap) I loved the way the cam felt with stock OEM heads but this is going to be a very different build in the end.
Overall lift between the two cams is about .018" but as we all know its not all about lift. So we decided to add a bit duration in the mix too.
237* int
251* exh
I wanted the car to retain some personality at idle so this cam only adds 1/2 a degree towards a "smoother idle" 113 lsa +4 adv and adds 3 degrees of over lap totaling 18 degrees. Which should help give the car a decent bottom end and a good mid range that will pull all the way up to the top.
Wow.. you're just a different beast lol
Curious from someone who's only done valve adjustment on a S2k before (the most I've opened up an engine), do you have prior experience disassembling an engine or are you more like a "how hard can it be" warrior? lol

LOL!! THANKS.
No I'm no different anything. My father was a mechanic growing up, I picked a thing or two up from him. This is the second time that I have taken this LS7 apart. I have disassembled/assembled an engine or two in my day.
I am just taking my sweet time. Making sure every bolt is torqued. And enjoying every opportunity I have to make sure this thing is well put together.
How hard can it be warrior?? Nah.
I am just following the instructions out of my 800 page Factory engine service manual and doing whatever it says for me to do LOL.
If you see I reference the book any time I tighten anything down. Adjusting valves is actually more complex than whatever it is I am doing LOL!
I'll be posting more pics soon; I anticipate within a week or two.
Now that the bottom end is all closed up, I will be plugging all the port holes and cleaning all that oil and grime up so its nice and pretty prior to install.
Sounds like an awesome build!! What's not to like??? Also, I really like you're staying with 8mm rocker bolts. I think people are sometimes carrying a bit of original SBC tech into the LS arena. I did for a bit. Anyway, if it was an 8mm rocker STUD, YES, that would suck. But it's NOT, so it doesn't!! That 8mm (probably a 10.9 fastener) bolt can apply tons and tons of pressure to keep the rocker in its 'nest'. 450-500lb springs OTN won't phase an 8mm, 10.9 bolt in the least. Haven't looked up the tensile strength, or the amount of force it can apply. But I do remember a 1/4-20 nut can apply many tons of pressure, and the 8mm is much beefier yet. My LS7 has a bit smaller cam than yours. It's a Futral/Cam Motion grind. Mine has .603"/.608" lift, duration is 232°/250°, LSA is 112°, +4°. It has 17° overlap. As for streetability, I get 21-22mpg on the expressways, 14-15 around town, and its an A4 vert with a 3,200 stall Yank. Very little problem with bucking/surging. No, I'm not here to tell you it drives "just like stock", because it doesn't. But it does drive EXACTLY like stock once you're at any speed over 55mph in OD.....EXCEPT for the acceleration part!!! TRUTH!!! Best of luck on your build......
