If you have the specs handy can you post. I know they changed and went to roller with the 850 and did a quick search for them but what I found did not look right.

I thought they were all roller cam shafts.............I purchased the engines NEW and never ran them as 850SC engines. Actually, I had them upgraded to 1200HP by changing cams, springs and some reprogramming. Could you tell if I sent you a picture ?

No I believe 800 sc - 575 sc was the hyd flat tapped they used for years. I originally thought the 850 sci was the same as the 1075 however the 1075 is a solid roller I do believe.

850SCI, 1075SCI and 1200SCI are all he same except for the cams and some ECM programming. I am 99% sure they are all solid lifter cams

I think they are the same camshafts for all of them and they use different pulleys on the superchargers and different ecu.
They do not have a distributor gear and a fuel pump lobe.
