We’ve known Brian Liebig, owner of GEN 2 for well over 10 years. He was the lead machinist at Arizona Speed & Marine before the owner retired several years ago. We were so happy to learn that he had opened his own machine shop and is now an advertiser in Roddin’ Arizona. Brian has over 30 years of engine building and machining experience. He’s a true chip-off-theold- block; His father has nearly 60 years of engine-building experience and the two often collaborate about everything engines and racing. Brian was instrumental in building the Porsche and VW engines that set Land Speed records at Bonneville. The GEN 2 machine shop has all the proper machines, by Sunnen, Robin (valve seat machine), Sharp, BostoMatic and others, including two in-house CNC machines. In the very near future, one of them will be doing CNC cylinder head porting and many of Brian’s programs are now computerized for CNC machines. CNC porting is more efficient and consistent than head porting. Engine machining and engine building are specialties at GEN 2. Brian says “we work on everything from Lamborghini’s to lawn mower engines, including Porsche, Mercedes, Mazda speed 3 & 6 and of course GM, Ford, Mopar and others”. House specialties include cylinder head porting, polishing, and flow bench testing. They also repair and do upgrades on ALUSIL aluminum cylinder blocks such as Porsche, Lamborghini and other exotic makes. I had recently purchased the small block Chevy V-8 engine that was purpose built for a ‘56 Chevy. The engine had aluminum heads and a pretty aggressive hydraulic cam. This engine will be going into my 1970 Camaro, but l wanted a milder cam and Brian advised that the DART Iron Eagle cylinder heads would be better for normal driving conditions. He also advised that they are very good heads!!! A cam change and head swap may seem simple, but to make sure it was done right, l had Brian handle the entire process. There were several things l didn’t even consider, such as push rod length and if the valve springs were right for this new cam (which they were). Brian’s shop is one of only two in the valley that has a state-of-the-art Buxton Engineering valve spring checker. He also used all new ARP bolts on everything that didn’t already have them (oil pan, intake manifold, headers, water pump, carburetor etc.). He suggested that aluminum valve covers would be better sealing and better long term than the stamp steel covers that were on the engine. So, I made a quick trip to Ramjet’s Speed Shop where they had a set in stock. Call Brian at GEN2 at 480-217-2640, conveniently located at 10201 N. 21st Ave. #9 (corner of 21st Ave. and Cheryl Dr. in Phoenix). Please mention Roddin’ Arizona when you call.
