I'm running a 4412 on a Old style Performer intake. How do you know were to put the spacer as far as sliding it forward or backwards? Thanks

Trial and error. Under hard acceleration fuel goes to the back four cylinders so moving it forwqrd might prevent a lean burn up front.

Check to make sure the throttle bores match up with the intake opening. You dont want the intake opening being smaller under the throttle plates and restricting airflow.
