Review on 🚀 Performance Boosting Comp Cams K12-602-4 Big Mutha' Thumpr 243/257 Hydraulic Flat Cam K-Kit for Chevrolet Small Block Engines by Jason Olguin

This is a well designed cam for a great sounding hot rod. small base circle. For this reason I had to send the cam back. When I bought the cam I didn't realize it wasn't cut on the small base circle as the cams I have fitted to this engine in the past were cut on that small base. basic circle and didn't cause me any problems. I'm sure it will work well in standard 400s and 350s and other small block Chevrolets with stock crankshafts (no engine). Sincerely, Handy7rick at yahoo.com
