Big Block Chevy Camshaft Belt Drive – Raised .400 Cam #5101


Big Block Chevy Belt Drive for Raised +.400″ Cam Height Blocks. All new design with superior features not found in other belt drive systems. Most notable, the Innovators West Belt Drive system incorporates an idler pulley which prevents belt deflection under high load and it’s adjustable to set the belt tension (and allow adjustment for stretch). We use a 20% wider 30mm Supertorque belt for even more strength and load capacity.

We did not cut corners on design for cost! Our belt drive utilizes low drag torrington thrust bearings instead of bronze washers. You’ll also be pleased to see we have a built in O-Ring on the cam seal plate for leak free performance! The features do not stop there, all hardware is the absolute strongest and highest quality possible, see below for even more details.
