KTUNED SIDE FEED in BLUE SKUNK2 ULTRA SIDE FEED in RED by Kerry Smith

back to back pulls, skunk2 ultra race manifold is tuned to this engine and the ktuned side feed was not tuned due to it being quite obvioius it performs better on this application. Skunk2 ultra race had a 4piston cnc port job that matched the pro 156 4piston cnc port job on the head of this K series engine.
