For a #4781 use #80 jets in the pri. and sec. Thats what they come from Holley with.
There's a variety of 850's. Check the info on this site Mortec/Holley carbs against the Holley List# on your carb(on front of choke tower).
Thanks for the infor guys, I think I will start out with the 80's. The choke horn has been milled off so I'm not sure of the exact model #
