217/23X, .619/.607, 114 LSA This new version of our Stage 1 PDS camshaft makes more power and torque everywhere in the curve compared to our legendary PDS cams. Developed in house, we went back to the drawing board and found more power and torque even with the use of less intake duration. These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards. Options: Cam Only Cam, .660" Dual Valve Springs with Titanium Retainers - BTR 7.400" 5/16" .080" Chromoly Pushrods Ships Direct From BTR E85 fuel is highly recommended.
