Written by Moore Good Ink Columbia, SC: When installing an aftermarket clutch on any of the vehicle models listed below, there’s a strong likelihood you’ll require a hydraulic bearing kit with more flexibility than that of the stock system. 1998-02 Camaro-Firebird 1997-12 Corvette 2010-12 Camaro 2003-06 GTO 2003-up CTS-V 2005-up Mustang V8’s 2008-up Challenger Ram Clutches tells us their new all-metal units are stronger and function better than the partially plastic stock bearings. They also provide more travel than stock, and include all the necessary fittings and lines to adapt to these vehicles. Their hydraulic bearing kits are not only complete but also they are engineered to fit properly, requiring no extra parts. In addition Ram’s Dual Disc clutch units for these vehicles are also engineered to be an exact fit. No surprises!

Jon Kaase’s P38 Canted-valve Windsor Cylinder Heads Aim For Better Cylinder Filling Text by Ro McGonegal Photography by Moore Good Ink Jon Kaase keeps his eyes peeled. Over the years, the engine builder has seen an endless string of improvements and aftermarket components visited upon the Windsor 302 but he was woefully aware that there were no real advancements beyond the original cylinder head configuration. He thought he could produce castings that looked like ordinary Windsor 302/351 parts on the outside but would be entirely different from the original blueprint on the inside. As a racer, he knew the value of stealth. But more importantly as an engine builder he knew the prime advantages of canting the valves to lean towards the center of the cylinders and so mitigate the natural shrouding effect of the cylinder wall.Kaase designed the P38 cylinder head primarily for the 302W (8.2-inch deck height, 4×3 bore/stroke, 5.095-inch rods); its derivative the popular 347ci (over bored by 0.030-inch and stroke increased to 3.400-inch); the 351W (9.5-inch deck height, 4×3.5 bore/stroke, 5.960-inch rods), and the 427-454W Sportsman-type Dart block (9.5-inch deck height with 2.750-inch Cleveland main journals). Typical combustion chamber volume is 60-62cc.To insure optimum cylinder filling, Kaase canted the valves at 8×4.5 degrees on the intake and 10×4 degrees on the exhaust. The fresh area created by the new valve angles allowed an increase in the diameter of the valve heads to 2.100 inches and 1.60 inches.Astute CNC porting would induce far superior air flow and cylinder filling compared with any conventional layout and it accomplished two things: the revised angles place the intake valve...

Written by Moore Good Ink Dawsonville GA: Air cleaners are not normally noted for their ingenuity. But this one might be. The hallmark of a great air filter is one that does more. Measuring 14 inches in diameter and supplied with a 3in deep filter element and featuring a recessed base to maintain a low profile, Demon Carburetion’s newly designed air cleaner (PN 786004) was conceived initially to suit the latest 625cfm Street Demon. But senior Demon designer, Larry Tipton, cleverly introduced a return flange to the bottom of its recessed base, at the gasket surface, enabling it to accommodate not only the Street Demon but also all modular-style Demon carburetors, including those with choke-operating mechanisms. Early Demon carburetors were principally designed for racing engines and as such had no choke towers. Later models prepared for the hot rod market, however, exhibited streamlined choke towers with linkages that sometimes interfered with existing air cleaners. On this new Demon air cleaner the return flange provides an adequate margin of operating clearance. Replacement air filter elements, 3 or 4in deep, are readily available from most auto parts stores.

Written by Moore Good Ink Winder, GA: The allure of Jon Kaase’s canted-valve P-38 cylinder heads increases with the addition of the smooth, rich shapes of his cast aluminum valve covers. For 302 and 351cu in small-block Ford Windsor engines they are available in black, red, or natural alloy finish or, indeed, any color desired. In addition they feature a revised bolt pattern specifically designed to fit the unique P-38 cylinder heads. Originally the stimulant for P-38 power came from Windsor enthusiasts who desired race-quality cylinder heads, but with the intake entries and the exhaust exits in the original positions. To this end, Kaase set about canting the intake and exhaust valves, mainly fore and aft. This created a useful improvement, eradicating a shrouding deficiency between the cylinder wall and the inlet valve and dramatically increasing cylinder filling. Beyond this the act of canting allowed him to increase valve diameters, particularly the intakes. In addition he quickened the port velocities, deepened the bowls, introduced efficient, sweeping short turns in both the intake and exhaust tracts, and improved the combustion chamber shape. A rare treat, Kaase’s credentials ensured the P-38 conversion kit would create a favorable impression when it arrived on the scene in August 2011. Now what greater pleasure than to have the first P-38 in town with appropriate valve covers? Kaase completes 50th Boss Nine build The Boss Nine seems the ultimate triumph of the rational mind. Seemingly unrivalled by any comparable hot rod engine it has several things going for it: it is the supreme cruiser—owners tell you, “It’ll take you to the moon and back,” and...
