Lav Keans - Hemi Holden Repco Crossflow

John Keans Repco Crossflow

When GMH get-go introduced the Holden, petty did they realise the potential of the 132 cu inward. side plate motor. John Kean a commission member of the Queensland Division of the FX-FJ Holden Club of Australia, has tapped a root of additional power to boost the ordinarily sedate 57 bhp side plate to a genuine 145 bhp. This legal bolt on conversion allows increased functioning without defying the Queens-country regulations regarding plumbing equipment mail service 1964 reddish motors in early Holdens.

At a fourth dimension of rekindled interest inwards these cars John'second FX is well worth a moment glance. The torso is a strictly original 48-215 which has been magnificently detailed. Before its restoration the motorcar was stripped to bare metal so painted amongst vii coats of black acrylic lacquer past Brisbane spray painter Gary Juster. The motorcar was completely rewired by Gary Lawson, an old hand at Eary Holden Electrics, to take a 35 amp alternator as well as 186 starter motor which was modified alongside a Toyota Crown effort. HQ sealed beam caput calorie-free units which incorporates the common lights were fitted inward keeping alongside early Holden pattern.

Warren Lee reupholstered the seats too reduce, alongside off white vinyl together with contrasting black flooring mats. A highlight is the all novel chrome.

But what makes this car distinct from other early Holdens about today, is that it'sec been fitted with a Repco high ability head. This cast atomic number 26 caput was purchased for $250, ported together with polished past John, then refitted amongst paw made authentic steel valves held inward place by alloy valve caps in addition to surrounded by 'Kawasaki 900' valve springs. He as well fabricated the exhaust extraction organization himself.

The head is mounted on a criterion iii" 132 cu. inwards. block and since ability is largely a office of valve timing, a particular cam was designed past Eddie Thomas to optimize ability. Only 200 of these 12 port cross-flow heads were ever made. They were originally introduced in 1956 together with sold for 150 pounds which included pushrods valve gear too inlet manifold to arrange either SU or downwards draught Weber carburettors.

Head pattern was past Phil Irving. it incorporates hemispherical combustion chambers with inlet too exhaust valves opening into it from opposite sides. Each exhaust valve has its own port as well as the inlets are fed inwards two groups of iii by individual as well as near straight ports leading from galleries formed partly past the caput as well as partly past the bolted on manifolds which tin can be varied to arrange the types of carburettors employed.

Dynamometer figures using a Std Bore seven.9:one motor fitted alongside a total race cam indicated 137 bhp at five,500 rpm. However using high compression 3-3/sixteen" pistons it is possible to boost the bhp to in excess of 190.

As John intends increasing the power output above its present 145 bhp he finished off the motorcar by plumbing equipment a HR disc brake front end end.

The bring up cease is as well HR merely the diff centre is express slip amongst 4.85 gears which makes the motorcar real quick off the grade. These diff gears are besides rare equally entirely 100 were manufactured past Perkins Engines Aust. to adapt the Holden Hemisphere as well as this was inward 1957. Two together with half years as well as $3200 have gone into this good thought-out rebuild and conversion.
