Can you fellas help me find the phone number to Motor Machine and Supply in Tuscon Arizona? The number I have is 520-792-1156 and it has been disconnected. David Vizard makes mention of them alot in your magazine. Thanks.  

I found the answer: http://www.gofastnews.com/board/engine-technology/219-how-contact-denny-wyckoff-cam-guru.html

From that it looks like the owner has retired.

Vizard has been thinking of offering the service himself.  Maybe post in that thread and see if David responds?  He runs that site.  

Hey man, thanks. By the way, what all do you have in your 406 and what does your Z run? Looks like a pretty good ride.  

Thanks, there's a lot on my site, http://AlteredZ.com
But here is a quick run-down:

406 SBC (4.155" bore, 3.75" stroke)
(Dart Sportsman Block, Scat 9000 crank, Cat 6" rods, Probe SRS forged dished (15cc) pistons, ARP throughout bottom end)
10.3:1 Static Compression Ratio
Canfield 215cc heads (flow #'s here: http://alteredz.com/data/canf215flow_1_data.htm)
I have a Victor Jr, but am considering a Performer RPM intake
830 cfm HP carb with annular boosters
1-3/4" block huggers, 2.5" exhaust, x-pipe, hemi super turbo mufflers
Solid Roller Cam, probably will be a 280XSR Comp Xtreme energy lobe for both Int/Exh on a 106 lobe center, at 104 ICL.
Isky Red Zone lifters

5spd (G-Force T-5)
3.7:1 gears
25" tires
2800 lbs w/o driver

I use it occassionally for street and at road course track days at Summit Point WV.  Will be at VIR on 2 July and Mid Ohio in early October for the ZCCA Zcar convention track day.

Cheers,
Pete
