525SC, used the same 228/236 at .050 530/551 lift 114 LSA flat tappet cam, that was used in the 400hp, 420hp, and 425hp mercruiser 454ci engines.

The 800sc (not 800sci), 600sc (not 600sci), and 575sci, used the same cam. Which was a 240/240 @ .050 .559/.559 lift 110 LSA hydraulic FLAT tappet cam.

The part #'s for the camshafts, are not the same in merc's parts diagrams, so I would say, no , the 900sc carb engine, did not use the same camshaft , as the 1075 EFI.
The 900sc's were known to be valvetrain eaters. I wanna say they had something like 714 lift solid rollers. They used conventional rockers, basically old school blown big blocks like alot of us have. Nothing fancy.
Personally, If I was rebuilding a 900sc merc, I would go for a milder camshaft setup .

and the sci engines don,t have a cam lobe for a fuel pump so the part number will be different.

I dont think he got his answer yet. He was asking on the 900sc cam specs. I think the specs you gave earlier, were for the 1075sci cam.

Hey Mike I believe it is a solid roller 252/257 672/672 on a 112 with an Iron gear .030 hot lash, but if you can call to find out that will clear this up quickly for the OP
