Interested in hearing the cam.
I like the red jethot ceramic coating on the headers.
Love the rims

I saw the finished product myself over the weekend.
The exhaust is actually a little quieter at idle than myself or anyone expected. It's raspy when you hit it though.

As for the headers:
They are "transformers".
The car was warm when I got there, and I opened the hood to look at them; and they were nearly totally black. I figured "Eh, they are filthy already".

Then my tuner said, wait 10 minutes and go look at them again.
Damn if they weren't bright red again!
Kind of opposite of what you expect!

290 - 295 = A4
300 - 305 = MM6

Mine was 309/322

I have not taken the car home yet.
It's developed a squeak we are concerned about.

It's just like this thread:
https://www.corvetteforum.com/forums...be-squeak.html

Heard:
Idling, with clutch in, or clutch out.
My tuner/techs can't seem to pinpoint it.
It's not an accessory, as they briefly ran it without the belt installed, and it was still there.

Any ideas?

Cam bolts backing out? Insufficient clearance grinding inside the front engine cover to accommodate that double-row timing chain?

Well, I drove the car twice today, back to back about 2 hours apart.

First ride was with stock suspension.
Second ride was with C6 sway bars and shocks installed.

WOW, that was a fantastic investment!!

The car is a beast. We've determined the 'squeak' is more of a 'whistle', but we have not figured out where it's coming from yet.

It doesn't quit right away when you shut off the car. It's more of a bleed down of air pressure. We do not have a vacuum leak that we can see, feel, find, or register on the computer. I am confident my team will find it though.

I'll be driving it to a Cruise-In tomorrow night and Cars & Coffee on Saturday.
STOKED!

My tuner said he had it up to 170mph on the dyno...
...in 4th gear!

That seems pretty high. I've taken mine to 150 with no problems. All Tha time I do pulls. But that seems kind of high. I myself have a forged ls2 but I would worry about taking fourth that high.

The car looks really nice, and the mods sound amazing. Are you running all this with a stock clutch? I have a 2000 and I stopped at headers intake and tune as I figured that's the limit of the stock drivetrain.

I will get the final numbers today. I think the sway bars and shocks may have added a few ticks, and I have not put on any skull stickers yet.

Yes, I am still running stock clutch. I asked that question some time back, and several folks said they've been fine with stock clutch.

I don't have any issue with upgrading it, but I'm going to run around with stock clutch for a while. I don't drive the car really. It's a garage queen, and will see a few 1st-3rd romps up to 4500 RPMs or so on the way to C&C/Cruise nights. (Yesterday was the first time I have EVER taken/shifted high enough to have the SHIFT idiot light come on.)

Next is the shifter, and some interior aesthetics upgrades; which will all go in at same time.

Best we could get at nearly 90*F and summer humidity....

I may try again in the fall for that "0" on the end.

459.96HP
401.45TQ

SUPER happy with the results.





Steve said these cars are almost exactly 15% parasitic loss from the drivetrain.
That puts us at ~541HP at the crankshaft.

Update:
We found the squeak/whistle.

It was lower crankcase vacuum. It was sucking air through any hole it could find from the top of the engine to the bottom. Pull the dipstick at idle when it was squealing and it sounded like it could suck a grape down the dipstick tube. A little crankcase ventilation adjustment, and we are good.
