[DMCForum] Volvo B280f (was eagle premier)

["cartermartin" <cartermartin@xxxxxxxxx>]

The re-designed b280 heads actually would squirt oil on the cam lobe 
i think.  I suspect the oil passages may have been improved, i'm not 
sure. I would have to dig out my service manual. There were numerous 
improvements. Here is a brickboard link that explains some of the 
differences:

The problem is the heads off a b280 won't likely fit your engine. You 
would need a complete engine. A 760 '87 or later is desireable since 
they had the better engine. The 260 had the same engine as you have 
now (B28).
