Camshaft is a custom 270 at .050 and .614 lift at the valve solid flat tappet.
We have been running vp e85 and water temp 175-180 when staging.Best 60 has been 1.39 with better air than lately.
Fuel bowls are half way in site glass.I believe it has pink pump cams.


In my opinion, it needs the 50cc green pumps & get the assortment of cams for the 50cc . just like bigger jets when going to alcohol it will need more squirter volume

I have an assortment of the pump cams and could rob some 50cc pumps off of another carb i have that's not in use.
I will say this fuel is very consistent.
