Holley on a Performer... Which spacer?

[PodBoy]

Should I use a open spacer or a 4 hole type for the holley? Thanks!

Without knowing the carb size and the car details, I would recommend a small open spacer. Say 1/2" or so.

Have fun.

Sorry, I didn't think through it. It is a 870 Street avenger on a stage 1 engine.
