Default Fresh Off the Dyno literally 451 stroker #'s
this is just a example of the kind of work we do here at Cunningham Motorsports.

Car: 02 C5 Z06

Motor specs:
451 ci 13.1:1 compression Engine Built in house by Cunningham Motorsports
Resleeved ls2 block by Race Engine Development
Custom Wiseco 4.185" bore Pistons
Lunati Pro Billet Rods 6.125"
Callies 4.1" stroke Crank
Wcch Stage 3 ported Ls7 heads (factory Ti intake valve, SS ext)
Cms custom hydraulic roller grind cam (247-263 .661" INT/EXT 114+3 Comp LSL lobes)
Intake:
FAST 102 Ported at CMS/NW 102 TB
55lb injectors
Exhaust:
ARH 17/8" to 2" step headers
CMS custom dual 3" over the axle exhaust

Dyno results 619rwhp 545rwtq tuned in 1 BAR SD on 100 octane, with 26 degrees peak timing, AF 12.9:1




mind you my dyno reads a tad lower then your average dynojet, regardless of numbers this car runs hard, it has gone 6.45 @ 109 mph in the 1/8th @ 2000+DA on the Base break-in tune

Nice. Any pics of your port job on the intake? How much can you safely bore out an ls2 block anyways?

Not everyone has the goal of barely streetable with a huge cam and a ragged out tune to make the most power.

+ running a 6.45 @ 109mph in the 1/8th on not even the final tune is no joke...the motor isn't in it's numbers, it's in its performance

Great job Ryne and crew, can't wait until my 416 gets together!

yes, but that was never consideration for this car, i would likely have to run a half point richer and run about 6-7 less degrees of timing, which would sacrifice alot of power, which at that point you might as well of just built it as a 11.1:1 motor

Excellent build. I really enjoy driving the big motor 427"-454" builds that keep the manual transmission... way to much fun.
