Hey guys! Just made my account, I found a modded 08 z06 thats pretty well built in my area for a decent price. There is info I'd like to know that the previous owner doesn't have, he is more of a cosmetics guy and didnt have a ton of info. So I figured I'd ask the pros.

First-The build
Callies 447, 15k on the motor
4.155 Wisco dome pistons (prev owner not sure what dome)
4.125 Eagle crank
Eagle I beam rods
Mast 305 LS7 Black Label heads
Solid Rollers, stated they were/similar to LS9 units,, I asked about setting valve lash and he said you didn't have to....doesn't make much sense,
Full port/polish by Frankenstein
Custom ground nitrous cam (this will come into play later, guy didn't know specs)
Ported MSD intake, ported TB
1000cc injectors
Nitrous Outlet standalone
Nitrous Outlet Pro Max controller with screen and switch panel, 2 10 lb bottles, was told it was a 250-300 shot, but I dont plan on spraying
Stand alone fuel cell (c16) for nitrous
Lingenfelter 2 step box
ARP crank bolt, PIN crank
ZR1 shifter box
15 inch conversion w/ welds and tires it comes with
RPM trans cooler delete kit
New z06 diff w/ 10k miles
ARP everything

So......Onto the questions.

1. What do you guys think? Opinions?

2. Can it run pump gas? Only E85? A blend?Browsing the forums it seems the dynamic CR is more important, but not knowing the cam specs leave me at a loss for figuring that out without pulling it apart. It has a 12:1 Static CR he told me, it's going to be mostly a street car and theres only 1 E85 pump within 40 miles of me. Trying to make my life easier but not trying to blow it up but asking about pump or E blend. He said he was told it can run on pump but he only ever ran it on E. Not really trying to risk it.

2. I need to do some reearch on the nitrous kit, never really messed with it in the past due to not wanting to blow stuff up. Still want to know about the system and how to use/how it works, but odds are I'll probably pull it out. Anyone have this kit that can give me some basic pointers?

3. Do the solid rollers really not have the ability to be adjusted? I've never owned a solid roller car but I know typically they need the valve lash checked/set every 10-15k.

4. How the Lingenfelter 2 step box works....I watched a couple youtube videos and there really wasn't much explanation, just the install procedure.

5. Any specific oil/weight for solid roller engines? I know some places say zinc additive, and some say don't bother worrying.

6. He said fueling was the limiting factor, said it made over 600whp but was maxing out the system so they backed it down to 580...What's the next move, a bigger pump?

I'd rather come straight to the source, so I'm gonna apologize now for my niavety, the C6Z06 has always been a dream car and I recently was able to afford one, this one just has a lot of work done for a fair price and not a lot of the info on the forum is really tailored to a build like this. I can find snippets, but I'm looking for definite facts.

Thank you all, happy to join the club!
