lt1 throttle body

I bought a Holley TB but the air holes in the intake are smaller then the tbs would it be better to match the TV holes with the intake?

You must have gotten a 58mmI tb. You should have your intake holes opened up to match your tb.

Yup, gotta match the intake to the TB. It's best to do it off the car but a lot of people have stuffed rags soaked with oil in the intake and then matched the holes to the TB.
