Curt Connors and his family are well known around the Mid Michigan Motorplex. They are die- hard bracket racers that make the weekend a family event. Curt’s wife Melissa and his parents all spend the weekends at the track most of the summer.
Curt’s 84 Monte Carlo is back halved, with a Mild Steel Cage. The Dana 60 houses 4.56 gears spinning 14×32 Goodyears. The car is all steel except for the hood and decklid, with stock glass throughout, but Curt has managed to get the weight down around 2700lbs. Just right for the Transmission Specialties Powerglide and 8” race converter to do their jobs.
The engine combo is a straightforward setup. It is 403 CID, based on a 6.0L LS1 truck engine. The stroker kit consists of 4” stroke Callies Compstar crank and 6.125 rods, and Autotec flat top pistons. Final compression ratio is a hair over 13 to 1. The heads are CNC Ported RHS units from Competition Components, with 230CC Intake runners, 2.080/1.600 stainless valves, and optional solid roller springs. The cam is a custom solid roller, with 260ish duration, and .750 lift. Lunati roller lifters and Trend heavy wall 5/16 pushrods make sure all of the cam’s lift gets to the T&D 1.7 ratio rockers. The engine is topped off with a hand ported Edelbrock Super Victor intake and a Holley 950 gas carb. The stock LS coil packs are run by an MSD timing controller. Headers are modified Schoenfeld Circle track headers, that were coated at QC Coatings in Utica, MI.
Curt’s first time out with the new combo was at the final test and tune day in 2012. Baseline passes were in the 9.80’s @ almost 138MPH. There wasn’t any time for any real tuning, just a few shakedown runs. For those first few hits, Launch was 5200RPM, and shift points were 6700. For next season, Curt has a new converter from Lenny at Ultimate Converters in the works, as well as some other refinements in the works. We are as excited as Curt to really put this combo to the test during the 2013 season. Stay tuned for more results!

RHS® is introducing the latest addition to their brand new line of LS application cylinder heads
This is the aftermarket’s only high performance LS7 head with a raised intake runner design specifically engineered to accommodate production and aftermarket LS7 intake manifolds and valve train setups. The 12° valve angle (flatter piston to valve angle) and unique .220″ raised intake runners provide a better line of sight into the cylinders and allow for an improved short turn. In addition, the custom CNC-machined runners optimize volume, atomization and velocity.
The 355T6 aerospace-grade aluminum alloy heads also feature the popular LS 6-bolt head design that makes them compatible with both the RHS® LS Race and GM LSX Blocks. This design also increases clamping capacity to improve cylinder head gasket retention on high horsepower and boosted applications. All of this, with the addition of a .750″ thick deck surface, increases the integrity in high cylinder pressure applications.
A reinforced solid rocker rail with extra bolts was engineered for shaft mount rockers to provide increased rigidity and valve train stability, while the raised .400″ valve cover rails provide clearance for aftermarket rocker systems. And finally, the raised runner and rolled valve angle increase overall flow capability. These features, coupled with an improved water jacket design, make this an ideal head for both small and large cubic inch, hardcore street applications.
12° Valve angle & .220″ raised intake runner over stock LS7 provide better line of sight into cylinders and short turn
We have added Comp Cams roller rocker arms to our web store at discounted pricing. We have added the Ultra Pro Magnum, Ultra Gold and Shaft Mount Rockers to the store. Check them out here.
