Congrats! You have an Aussie Ford carb, 800 cfm. Originally off a mid 1970s Falcon, 302 engine. Came with #2174 met rods, 070/038 steps. 101 pri jets, 098 sec jets. No not a misprint, sec jets are smaller!
Open the sec main air bleed to 0.040" [ stock about 0.029" ], drill the sec jets to at least 0.125" as a starter, & set air valve spring to 2 turns & you will have a real screamer.
