Red Horse Posted March 20, 2008 Share Posted March 20, 2008 Guys, Ca anyone shed some light on non- turbo 673 variations. I have a B 68X that someone at some point in time yanked the gas engine and put a 673 in its place. This engine is as basic as you can get. The street side of the block is clean with nothing but the intake manifold on it and two oil hoses that go to/from a Luberfiner. I also have a B-61S that is a 1963 and has a 673 thst is totally different. Instead of a single piece intake manifold, it has a split manifold plus what I believe is an oil cooler. Anyone have a clue as to the HP differences in these two motors? Quote Link to comment Share on other sites More sharing options...

Anyone have a clue as to the HP differences in these two motors? The one that does not have a oil cooler may be a 170 HP and no more and it does no have a full flow oil filter but a partial flow bypass meaning that the oil to the brgs. is not filtered before going to the brgs. and may not have a thermostst. The engine that has the 2 intake manifolds or P intake as they were called long time ago has a full flow oil filter and by pass combination. It will have a thermostat and more fuel set out on the rack and timing will be some different as well as a oil cooler and was a 187 HP so they will interchange but are a little different. The engine that does not have a oil cooler will have a big removeable cover on the bottom of the oil pan were you can take off and clean the trash out of the oil pump pick up screen and alot of people did not do that. glenn Quote glenn akers Link to comment Share on other sites More sharing options...
