Start out with your fuel pres at about 70 psi. that should make you pretty rich. Take a few hard laps come in and check plug color. If the insulators are dark and they should be back off the fuel pressure 5 psi and give it another shot. We like a nice light brown to tan color. The big motor was probably mechanical injection and requires a lot more attention than a modern electronic injection.

If you come to a MMSA race look me up and we would be glad to give you a hand. If you could get a muffler shop to weld you an O2 bung in the top of your ex pipe we would even lone you our Dyno Jet to check A/F ratio.
