Two 4150 750 carbs on a tunnel ram 403ci
13.2:1 compression with 92 degrees cam overlap.
Carbs are both setup with 35 ifrs and 70 iab.
Curious if anyone thinks this could potentially lead to a excessively rich idle circuit. Thanks

What are you using it for?

Try it first. If its pig rich around the pits, put the small wire in the IFRs.

Try .031/65.
