Stripmaster Manifolds were developed and designed For Holden V8 308 engines using B cast factory modified cylinder heads , Yella Terra cast iron and work well with dash 3 Yella Terra aluminum cylinder heads. The Holden V8 manifold was designed & developed by Peter Michael of PM engines. In 2010 the pattern equipment was purchased by Australian High Performance Industries the makers of Aussiespeed® street & race performance products.
The Holden V8 strip master pattern equipment was in rather worn condition externally and after assessing the Holden V8 manifold pattern it was decided that a rework & removal of some excess aluminum from the casting was called for. You can be assured that the internals of the
manifold have not been altered. The Aussiespeed® Strip Master manifold is slightly lighter in weight, the surface finish is a shot blasted stress relieved satin aluminium finish, it is machined for a standard deck height and many require additional machining to suit your cylinder head and block deck heights. A Recent independent dyno test showed the Holden V8 Stripmaster manifold gained 50 horse power and over 100 foot pounds of torque on a modified standard stroke 308 motor in a back to back test against another after market performance manifold. Aussiespeed ® offer a range of rocker covers, timing covers, valve cover spacers and many other performance parts for Holden 253 & 308 engines.The Stripmaster was never designed for 331 or 355 stroker engines and there are other quality brands on the market that will make more total horse power at higher RPM if a torque monster is what you want the stripmaster is worth considering.
The stripmaster has an overall height of 140mm measured from the flats on the base of the manifold to the highest point of the carb pad.
The only changes we have done are external changes to the tooling to reduce some weight out of the manifold
The Peter Michaels Strip Master manifold to suit early Holden b type cast cylinder heads. Aussiespeed had Dandy Engines put the manifold through its paces on the dyno engine was a hot street Holden 308 engine they were building for a customer.
The dandy engines built Holden 308 was run with a modified dual plane inlet manifold, with the stripmaster fitted in a back to back run the engine gained a straight up 50 horsepower with no carb jetting or ignition timing changes
