Upgraded my 67 Firebird 400

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.
