I'm a dummy. Cant quite understand total timing but here is first question. The new delco distributors I just installed include a timing "shunt" to be plugged in to set base timing. I get that. But when I want to increase rpm to 3000 rpm to check total timing, do I remove the shunt or leave it in place. Also, I am planning on timing my 454s at 3000 rpms to 30 degrees. Does that sound about right? Does that mean I simply want to set my timing light advance to 30 degrees and align it to the 0 mark on timing tab? If it is off at 3000 rpms, do i return to idle to make distributor adjustment and then back up to 3000 rpms to check adjustment? Thank you.
