Certainly....specs on the CRANE BLUEPRINT McKellar #10 SOLID LIFTER cam are - 236°/247° i/e duration @ .050" lift, 113.5° LSA, valve lift is .416"/.420" i/e Valve lash clearance is .012"/.018" i/e But I had to use 1.65 Melling rockers to get that lift. It's NOT .447" with 1.65's that's from the CRANE catalog, it's also what I remember from cam card. I can't find the cam card now, don't remember seat to seat duration. It IS noticeably longer duration, rougher idle than RA IV hydro cam. But less lift than RA IV.
The HO block just means 4 bolt mains nothing else. Find or mill up a pair of 96cc heads for pump gas. Use 2.11 1.77 valves. Get a solid flat tappet cam at least, or roller. Port the heads. Get a cam with similar specs. Also a Victor or Torker 2 intake, 800 cfm Holley. Headers. Electronic ignition .forged rods, forged pistons for durability. 80 lb. Oil pump. Double roller chain. Windage tray.
Could you tell me what the cam specs were on your #10 cam McKeller 455 was?
