Sport Mod Camshaft Rule Revision

Sunday, March 13th, 2016

In order to be consistent with all other tracks running Sport Mod we have made a small revision to the camshaft rule which will not allow solid flat tappet camshafts. The only camshaft that will be allowed is a hydraulic. The following rule will be in effect.

Camshaft-Hydraulic camshaft only. No roller camshafts allowed must pull (15in) of vacuum at 1000 RPM’ s. Must have access to vacuum port in manifold. No 4-7 swaps.
