Need Jetting Info for a new build.

[DragRacer383]

My engine was all stock, so I don't have a base line for the jetting for the changes I made. If all goes well I will have it together Sunday.

These are the changes from stock
Bored .050
Vito's super stock piston
Head milled .025
Mild ported jug
CT exhaust
Now another upgrade question. I have the Uni Filter Air Box Vents, I need to know how many to install in the air box lid. This will factor into the jetting. They are 1" in Dia.


Then the big question. I have the Vito's Jet kit for the stock carb. I need to know where to start, Using Klotz R50 mixed 40.1. W 100 octane.

The jet kit comes with
30 Pilot
290 main
300 main
310 main
320 main
330 main
340 main
the needle
I was thinking use the 30 pilot, the needle in the middle clip, the main I am not sure.


Thanks Glen
