Innovators West has revealed details of its new belt-drive assembly for big-block Ford 385 series engines.

The hallmarks of a competent belt-drive assembly are to generate less friction; effectively dampen adverse harmonics before they reach the valve train; maintain precise valve timing, particularly at high engine speeds; and demonstrate convenience in valve timing adjustments.

IW-BeltDrive1-webThe Innovators West new belt drive assembly distinguishes itself by not only accomplishing all these familiar requirements but also makes it available in two indispensable forms: one style is equipped with integral side brackets for serious track use, the other without.

The side brackets are regarded as unique. Provided with big-block Chevrolet hole spacing, they accommodate motor plates, power steering pump, alternator, crank trigger as well as external oil pump or a vacuum pump or a belt-driven fuel pump, often a requirement for turbo or blower engines. External competition pumps are customarily mounted on the 1/4in thick aluminum engine mounting plate, but this is rarely satisfactory as the plate is apt to deflect, resulting in imperfect belt alignment.

An adjustable drive-belt idler is included to allow for precise adjustment of drive belt tension. This is important when taking into account the production tolerances of new belts and the re-tensioning of used belts.

The crankshaft pulley is made from heat-treated steel and the cam pulley hard-anodized billet aluminum. For concentricity, both pulleys are machined in one operation in a multi-axis lathe.

Also, a cam retaining plate is provided with two encased roller bearings—one operates between camshaft and plate, the other between cam pulley and plate. Optional high-vacuum seals, alloy steel drive hub, and camshaft drive adapter are available.

In conclusion, these belt drive assemblies are now available in machined billet or a tumbled finish.
