Let me know,

I used my Barry Grant 750's and they were on the small side.

Besides them being a solid roller with the little maintenance I like the cams. With my smaller carbs it idles surprisingly well, but it does have the presence that there is a respectable cam in there. I run Stainless Marine dry to the tips, jacketed TRS tails so I was not worried about reversion. With the heads that JimV hooked me up with I am very happy. I built these engines off of base Merc 425's with a dual plane manifold, and knowing that I have TRS drives. I really didn't want to build some big cube engines with huge torque to blow drives. (that will come later)

I have not had them to full power in the boat yet only on the dyno. I had some fuel delivery issues and didn't want to risk them. But so far what I have experienced with them is a night and day difference compared to my Merc 425's.
