New products for Holden V8 applications
Now available our 4340 steel oil pump drive gears to suit all Holden V8 applications using solid or hydraulic roller cams. The genuine Holden part enabling the use of steel roller cams in Holden V8 engines is no longer available so we have made our own.
These gears are compatible with any steel roller cams in Holden V8's and are priced at $220.00 each. If you convert to a roller cam this is the only gear change required as the distributor is under almost no load and will not require a gear change from the stock carb or EFI distributor types to convert successfully to a roller camshaft.
Finally, we have a new design hydraulic roller lifter set to suit all model Holden V8 blocks prior to the last VT version. These lifters totally cure the problem of not being able to run high lift cams and loss of oil pressure with oddball base circle size cams.
Our full skirt design keeps oil galleys fully covered with cams over .600" valve lift enabling those converting to hydraulic rollers to take full advantage of the high lift cam designs we offer.
After all, the big advantage of a hydraulic roller profile is the high lift possibilities without cam wear problems normally associated with flat tappet high lift cams, as well as the extra power potential of the roller designs.
The big lift profiles produce excellent power potential with even conservative duration numbers as we have proven time and time again. Now you have a consistent source for your roller lifters without worrying about keeping lift numbers under .550" as the other aftermarket items available require.
Our new retro fit hydraulic roller lifter sets are $1430.00 a set and are a simple drop in. They can also be used to replace OEM lifters in the VT model blocks but the extra long VT lifter bores need to be machined down to suit the vertical axle design of our lifters. This also means the factory retainer plate and lifter guides used in the VT engine are also no longer required.
We have a full range of hydraulic roller cam profiles to maximise your results. We can advise on a suitable profile to suit your engine combination.
