Doug, would you like this post moved to the main forum?
Do you have visual emissions testing in your area?
Do you intend to keep the EGR functional, or change your distributor curve to work without it?
Years back I converted to a Holley 0-80457-S.
Mine is not set up for speed control or automatic transmission kick down.
I still have it in a box on the shelf, it was gone through with a genuine Holley kit not long before that.
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
