We added an underdrive pulley and got about 10 rw hp uncorrected. Jon Paul can post his dyno sheets later on along with his SAE corrected hp and torque. His car also made over 400 rw lb-ft corrected. Not bad for a stock bottom-end car. If youre in Houston, come out to Miami Subs tonight and check his car out. His Z06 even impresses me. Have fun,

Yes, Darth Vetter's Z06 has significant cylinder head work. Here are the details on our Z500 package:

Ram air induction
Modified MAF
Ported/polished cylinder heads (318 cfm flow on intake @ .600), 2.02/1.60 stainless valves, upgraded valve springs, titanium retainers, 3-angle valve job, surface heads
Camshaft upgrade (sorry we are not sharing specs)
1.8 rockerarm upgrade
Pushrod upgrade
Crank underdrive pulley & belt
Custom 1.75 in headers
Modified mid-section exhaust with X-pipe
B&B PRT exhaust
Custom engine management software (not on Jon Paul's Z06 yet)
Gaskets & fluids
Installation
Dyno & road testing
Limited 2/24 warranty
Z500 floor mats, dash plaque and exterior badges
430 rw hp & 400 rw lb-ft SAE Corrected (approx 500 flywheel hp)
1/4 mile: 11.9 sec (2.1 60 ft) @ 124 mph

Cost: $12,500. Intoductory price to first 10 Z500 customers is $11,000.

This is not the cheapest package out there nor is it the most expensive. Given the power and performance that it offers, I think it is quite a value. Thanks for your interest. We currently have a production capability of 1 car per week. Email me directly if you would like more info or would like to schedule an appointment.

Have fun,

Darth's car sounds like a complete beast. Darth or John, did you do a 3 angle valve job, bigger valves, better springs, different rockers, etc. Inquiring minds want to know.
