This kit converts your 1964-1967 326, 1964-1966 389, & 1967-1968 350 and 400 8-bolt timing cover/water pump to the better cooling, more efficient, 11-bolt style. Comes with upper pulley needed for the high flow water pump to work with all your existing pulleys and brackets.
Recommended with 1968 and later 4 bolt balancer with 4 bolt pulley (RAR-PUC-2B). Will work with 67 and earlier 2pc balancer but you may need to remark timing marks.
Will not work on 1963 or older that came with 4 bolt timing covers

Very nice kit for my 67 Firebird. My original timing chain cover was in bad shape, so instead of just replacing the cover with same, I decided to upgrade to this performance pump and cover. Easy install. My only suggestion would be to supply the cover studs with the kit. They are a pain to get out of the old cover.
