Winder, GA, January 2009: Though this new Boss Nine retrofit Hemi kit produces 100 horsepower more than its counterpart, the P51 Wedge—Kaase’s competent replacement for the Cobra Jet, it is not the power advantage that attracts the punters, but instead it is the look. Still the spectacle of a ‘69 Boss Mustang power plant maintains an indestructible image for many.
Intake Manifold: When tested on a 466 CID engine, the new intake manifold proved 50 horsepower better than the best NASCAR single-plane counterpart and 100 horsepower better than the factory dual-plane manifolds supplied with 1969-1970 production cars. Un-ported, this Kaase intake has sustained over 1000 horsepower on a well-built 600 CID engine. Moreover, on an engine as small as 429 CID, it has supported full engine loads at 2300 rpm. The intake, which also fits any of the OEM Boss heads, is available for either the 4150-style (750-850 cfm) carburetors or 4500-style (Dominator) carburetors.
Oil pump:The mounting foot of the OEM oil pump of a 385-series big-block Ford is prone to fracture. Kaase’s new pump has sturdy mountings to eradicate pump breakages and is equipped with dual oil feeds to improve idle and high-rpm oil pressure. It was developed to operate with front or rear sumps and is provided with superior ARP mounting studs and 12-point nuts.
