Any one know for certain what cam specs are for the 850 - 1075 sci engines? I found an old thread from 06 I think where Bob m posted them however the way he claimed that the 850 was a different cam than the 1075 and I was under the impression that they were one of the same. Solid roller. Thanks for any information on this.

Not sure what the specifications are but both the 1075 and 850 use the same camshaft. The Mercury Racing part number is 496-8M0043068.

GF?

Somebody has to have spec'd one out by now. I remember reading Merc was pretty discrete about this one. Lol.

I have a cam card from bullet cams,its from the 1075,252,257,ls110,.673",.673".thats the cam we put in after a lifter took a dump.
I have more specs on the card if needed.

if you want,I can text you a pic of the cam card.

What ? No 16 degree spread with Brodix heads ? LOL.

I kinda liked that... It was apparent something changed other than just the CI etc.

That would be great. Tks

I have the exact specs for both at the shop. I'll be back on Monday and can post them then if that helps.
