Thanks Bob,
Would love to get more info and be able to run it in Dyno 2000 and compare with the recomendations above. Then I will get a hint what will happen to my boat upgrading the cam.

Thanks!

The Ultradyne 288/296 cam is 231*/239* on 110* lobes @.050" lift.

Lift is .550" intk/.575" exst

Back in the 1980's, this is the cam that Merc used in their 454cu.in. 440hp Cyclone engine. They also used it in their 482cu.in. 460hp engine which actually made more like 475hp.

Goran; I doen't have pictures, but they are in perfrct cond., I also have stock merc, 420 exh., rear lower exits with tailpipes 3" I really doen't know what they would be worth, I have had them stored for a few years, make me a reasonable offer and you can have them.

thks Joe
