    1981 is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from Nice Ram but needs work Bought this legendary tunnel ram for my Gasser. Looks great but needed alot of work in the port areas to gasket match. I expected abit of work but it was along way out to one side. Next issue I found was the top plenum is very badly mismatched to the base. large port misalignments. You need to factor in when buying this to spend a few hours on port matching at least and sorting out the flow obstructions with the plenum. Other than this you dont have many options for an old style manifold to buy. Yes I would still buy another one.
