Two and three piece, T6 bullet timing chain cover and needle bearing idler sprocket, for dart engineering engine blocks with cam shaft .600 thousandths higher from stock location with removable upper half

摘要

The two and three piece bullet aluminum timing chain cover with removable upper half and adjustable needle bearing idler sprocket is a unique non-conventional timing chain cover and sprocket combination that utilizes a sprocket to allow a longer chain to be used for the additional height separation from crank center to cam center line. It takes up timing chain slack or excessive side play within the chain, and allows it to be mounted and assembled on Dart engineering Chevy Engine Blocks part numbers 31282465 through 31293875.
