Road Race C6Z, RHS 427, Carnage!
It isn’t everyday that we purchase, assemble, and ship a C6 Z06 road race car half way around the world to a customer in Norway, but when we do, it leaves the Vengeance Racing facility with a nasty RHS 427 under the hood and all of the power, torque, and reliability necessary for several seasons worth of high-power competitive racing.
Interestingly, this build started with an already assembled, highly competitive, and somewhat raw C6Z that we purchased from a local road racer to send to our customer in Norway. There was only one problem… The stock LS7 was, well, completely destroyed. Valve, meet block. Block, valve.
With the old motor out and the majority of the stock LS7 parts in the trash, we began assembly of the new 427, starting with a 4.125-inch bore standard deck RHS block. Our in-house technicians assembled the entire engine, which was built with reliability, longevity, and power in mind.
Engine:
RHS Standard Deck Block; 4.125-inch Bore
Callies 4-inch Crankshaft
Callies Rods
Wiseco Forged Pistons
Calico Coated Main/Rod Bearings
Mast Motorsports 274cc LS7 Cylinder Heads
VR Custom Camshaft
Morel 5206 Link Bar Lifters
Hardened Pushrods
Cometic 6 bolt MLS Gaskets
ARP LSX 6 bolt head studs
Cloyes Single Roller Extreme Duty Timing Set
Katech LS9 Oil Pump
Results:
With a focus on stout power production while maximizing reliability, we were happy to see over 50 lb-ft of torque carry horsepower to 577. On the track, this RHS 427 will power out of the corners and carry major speed on the straights, which is exactly what our customer was looking for.
577-rwhp / 507 lb-ft of torque

Vengence put a massive 427 in it. Wish I could take it to Road Atlanta for one last run before it goes to Norway.
Good luck with it

It was a great race car. I bought it new in Dec. 05, one of the first C6 ZO6 to be stripped and made into a full race car. I never broke the seal on the engine for a cam or heads, but it made 518 rwhp with LG Headers, Callaway Air Sytem and a good tune from Rob Walden.

That's some funny chit!
My only advice is......
...quit hanging around with Bob Mayer!!
I've had some great laughs with you guys, and I hate to see you quit. I've been going to quit 10 times, but can't ever quite pull the trigger.
As Peter Egan said, "Racing makes heroin addiction look like a vague wish for something salty."
And I can believe it!

I raced for six years on the stock brakes. It was not required in the seires I ran in for SCCA or NASA. The six piston fronts with some good Carbotech pads always worked for me. I saw no need to spend $3500 to $4000 to replace them.

I'm on the stripper part but my order is different
-started racing
-got divorced
-dating strippers
skipped the Harley part, no interest
I think getting married again is also a bad financial decision!
