Are these the part #'s for the inner and outer cam tensioners on an 88 cube motor, 39964-99a secondary and 39954-99a primary. Any help would be appriciated. I have 29,000 on the old girl, going to throw a cam in her and change tensioners , lifters and bearings while i'm at it. Wanting to place an order at Zanottis. Found the numbers using the search but mentioned something about new style and old.

 

just my 2 cents but if your going to spend the money on the new cams, bearings and tensioners Id probably go ahead and upgrade to the hydraulic tensioners. Thats what I just did and its worth it.

 

Those are the correct PNs for the "old" style, your style. Change inner cam bearings while your at it.

 

While i'm in their the inner bearings are going to get changed. As far as going with the new style cam plate, I just don't want the added cost. Ordered new tensioners from Zanottis and going to put them in whether they need it or not. Thank fellows.

 

Get the new oil pump as well. Far more scavenging and pressure. Cheap piece of insurance.
