Hey everybody....quick question for you guys. I have an 85 Z28 with a 305 LG4, with Vortec heads. I just bought a brand new out of the box 600CFM Edelbrock carb. I've done the adjustment of the idle mix, and the idle RPM, but the car doesn't drive as well as it should. The rods and jets are the ones that came with the carb when I bought it. I know I am being very vague, but my question is the following:
For my application, what rod and jet size would be the most appropriate (part numbers are accepted)???????
I dont understand, why does the chokemake the part numbers for the rods different????? Also, as far as the jets are concerned, which size should I be using???

Assuming that your idle mixture was set properly with a vacuum gauge, I would look into your timing and advance. I wouldn't worry too much about the rod and jet sizes, as they should be very close to what a 305 would need out o the box, even with the vortec heads....
