100S CAMSHAFT KIT

DWR 4 Profile is our 100S interpretation with 278 degrees duration, this puts it midway between our DWR 1 and DWR 2 Profiles in performance terms, providing good power with very smooth delivery. This 100S profile is equally well suited to the 100/4 - ideal for a Mille Miglia type rally car.

For a Camshaft Profile specification sheet please click the attachment below.

EXCHANGE CAMSHAFT KITS ALSO AVAILABLE - Reground old units limit the lobe size and position, with this in mind we only accept old units which have not been reground before both on the lobes and journals. Using the original material we heat-treat these to the best limits available. PLEASE NOTE:

Prices include followers and cam lube, but not pushrods.
