PRTCNEW CROW CAMS GM 6 AND V8CONICAL VALVE SPRING PACKAGESOne of the common dilemmas for builders of performance streetHoldens and Chev Small blocks is the desire to run camshafts withhigh lift being restricted by the need to run double valve springsand the associated expense, time and hassles involved inmachining cylinder heads to suit the bigger valve springs.Now Crow Cams have a solution utilizing their range of highperformance conical ovate wire valve springs and specially designedsuper-light chrome moly retainers to suit 0.343” valve stems andseven-degree valve locks.The conical spring design is well proven in many late model enginesmost notably the GM LS1 where conical springs are regularly used oncams between 0.550” and 0.600” lift at relatively high RPMs withoutstanding reliability and resistance to pressure loss.The “beehive” spring design combined with the small lightweightretainer resists valve float better than traditional straight spring/retainercombinations giving greater RPM potential. The standard O-ring sealwill not fit with this combination. You can choose positive guide fitstem seals or a Falcon umbrella seal is also satisfactory.The valve train weight saving in the retainer alone is significant withthe new Crow conical chrome moly retainer weighing a mere 11 gramscompared to a double spring chrome moly equivalent at 27 grams.Even Titanium double spring retainers are substantially heavier at 17to 19 grams.Two conical spring and retainer packages to suit Holden and ChevV8 and one for the Holden straight six are available.For more information call Crow Cams on 03 9357 0469 oremail sales@crowcams.com.auAN OIL TO HELP YOU SLIDELeading blender of Australian made lubricants, Gulf WesternOil has developed an oil to meet the demanding needs of theincreasingly popular motorsport of drift racing.No strangers to the world of racing,Gulf Western Oil has enjoyed a longassociation with Australianmotorsport, competing in theAustralian Touring Car Challenge andsupporting teams in the V8 Supercarseries and Group One Drag Racing.Its latest offering is a pair ofengine oils tailored to the highrevving, severe wear nature of driftand circuit racing. In response to thegrowing demand for aftermarket driftproducts, SOUGI M 5000 and SOUGIS 6000 were specifically designed forturbocharged engines operating under extreme loads, but arejust as at home with high revving, naturally aspirated six andeight cylinder power plants.Available in both semi (5000) and full-synthetic (6000)forms, the 10w40 viscosity grades maintain a silky-smooth revrange whilst maximising power output. Double bonded additivechemistry and enhanced molecular structure give SOUGI engineoils superior film strength as opposed to conventionallubricants.
