Max Power offers camshafts from the following companies.

Camshaft application varies greatly with each engine build, we will make suggestions to provide you the best performance for your application.

We use Web Camshaft grinds to achieve power gains not possible with the options from the more commonly available Hot Cams. Since they provide a much larger performance increase it stands to reason that they are also a more aggressive camshaft profile.

Most of the Web Camshafts we recommend require a spring kit or other head modifications to work properly. When the positives and negatives are discussed with our customers about 75% of them choose to go with a Web Cam.

Prices do vary but usually a single overhead hard weld re-grind cam will run about $240 when an acceptable core is returned. A set of dual overheard hardweld re-grind cams will run about $450 when an acceptable core is returned.

Description: This is a hardweld re-grind camshaft set designed for peak power gains, with some loss of bottom end. These cams work very well with our big bore and stroker kits because of the enormous gains in bottom and mid that come naturally with bigger engines. These can be used in stock bore engines but require high compression of 13.5:1 or higher to avoid the power falling off between gears.
