Thanks. Long story short. An eBay buy with a "modified engine". It had a header, dual 45mm side draft carbs, bored to 2.2 a "296 degree" cam, double valve springs and a few other things not relevant to this. It had a remote oil filter. The hoses burned through on the header. When the Volvo dealer in Lubbock replaced the hoses the mechanic reversed the hoses to the filter.Two blocks later engine quit, not seized, but not healthy. I'm in the tear down now, some fried bearings, one main and one rod. So its a learning experience. I have replaced the header with a dual downpipe and the side drafts with HIF6's. The cam has a "T" stamped in the end farthest from the cam gear and that is all. The lobes look good (I'm a rookie,how would I know). Both lobes closest to the middle bearing are ~ 1mm lower than that journal. I kept lifters and rods as pairs and in order. Some of the things in the ad were true, others outright lies. Most of the stuff about the engine has been true, but i've never heard of a "T" cam.
