cool thanks for the info.... still cool that i found a 4v 289 in my garage with all original hardware still on it..... after pulling off the valve covers, i could tell that its been sitting a very long time.... theres cobwebs in there and the oil looks like its completely dried up into very thick sludge.... and those shelby valve covers are probably worth something, but would look better on my mustang.... probably good for shelby cloning
