Some families have issues with sibling rivalry. Not Brian and Ed Sobczyk. They work as more of a team. It probably comes from years of working together at the family business, (TJ and Sons in Madison Heights, MI) where they work on daily drivers for local customers as well as lots of local hot rods.

Ed’s Pontiac combo is very similar to Brian’s Buick (featured below)

• Oliver forged 6.800 BBC rods 
• cast 4.250 crankshaft
• custom CP flat top pistons
• Moly ring set
• StreetPorted Edelbrock Performer Heads  (2.190/1.77 valves)
• Custom Scott Brown (Competition Components) Flat tappet Camshaft 256 @ .050, .600 lift
• Scorpion Rocker Arms
• Edelbrock Victor intake
• Quick Fuel 4150
• Custom PTC torque converter
• 4.10 Gears
• Full 3″ exhaust

Ed’s car is regularly street driven and raced at Milan fairly often. When this combo was originally put together, it had an Edelbrock Performer RPM intake, and ran a best of 11.14. The photos in this post are old, from the first day at the track with that combo. Upcoming changes include a dominator carb. The car weighs in at 3700+ lbs, and currently runs in the 10’80′s

The purpose behind this engine was to build a max effort street strip Buick 455 combo, using the new Edelbrock heads. The heads are fully ported and will be available from Competition Components. The car is regularly street driven, weighs 3900+ lbs and is cruised regularly, so race fuel was not an option.

At the Bonneville World Finals in October, Steve Benyo Destroyed the class record for C/PS by over 21 MPH. The old class record (which Steve also held) was set at 232 MPH. The first leg of the record run was 258+ MPH, and his second was 248. The two runs are then averaged for the record.  Beno’s 323 CID 4V Mod motor is developed by Scott Brown of Competition Components, and meticulously machined and assembled by Dave Weishaupt (Pops).
