Which size tillotson and fuel type?

[L79corvette]

I'm building a predator 212. I want to run a tillotson carb but i can't decide between Racing fuel or Alchohol. Which fuel is best and size carb would you run? Price doesn't matter in fuel cost.

MY SPECS:
Predator 212
18cc head milled 0.050 and ported
27/25mm SS valves
billet flywheel
ARC +0.040 rod
Stock compression height flat top piston (0.010 in hole now)
0.010 head gasket
black mamba cam with 1.3 rockers
My calculation for compression is 14.3:1

We have about the same engine in a racing kart and run it in the open class....we use a Tillotson HL -304 WXA...of course thats a alky carb...we got the whole set up from EC Distributing.

As said above on the Tilly and fuel...
I run the same except a older Tilly 348C... On alky...

On my other build I run a stroker crank, bigger cam, and big valves and had good luck with a hl360, or a hl380 Tilly...

But for 27mm valve a 304 Tilly is killer!!!!
