I believe that 's just lash...it has lash for 1.6, 1.7 (underlined) and 1.8.

So, giving lash for 1.6, you take that number, divide by 1.6 and times by 1,7 for lash at 1.7

Noone in the world would run 1.8's. The valvetrain would turn to dust. I believe 1.8's are custom rockers and are only available in the future. lol

I like how you worded that especially since many of us on here run 1.8's from time to time but just keep it quiet so others don't think your insane or mentally challenged. Well I guess I fall in that category and love it.
I'm not even gonna ask what you run or have run over the years. Lol.

Future??? Won't be to long and rockers will be a thing of the distant PAST. Lol.

Now your entering my world, but I'm not sure a 30 pitch 5 blade hering is a smaller prop.

I was just giving SB a hard time. All in good fun. I ran 1.8's for years (5 maybe 6?) I ran them to 6500 RPM's with my old Ultradyne cams. Cruise RPM's were mid 4000's. I'm switching to the Yella Terra's this summer and probably will go with the 1.75/1.7 combo. Also the Scorpion 1.8's I believe are closer to 1.83. I'll try to remember to measure the full valve lift before I pull them off.
