Yeah 9800x were universal fit 800 'Super Quad'.
The #6568 had increeeedibly lean sec jets, 0.098". Smaller than the pri jets, 0.101". Go figure how that works!! #2014 rods 069/054/040.
I am waiting for a special order 850 TQ from Summit. Recond, 6000 series & from memory it was under $200.
The ford has a smaller air bleed opening, thus, making signal pull on the secondary jet stronger which negates the need for huge mopar sized jets. Going to 137"s will make it pig rich.
Further, the primary side is also diffetent than mopar
