So I bought a new rebuilt big bore engine that says 73.0250 on the head and piston so what dose this mean and how many cc dose this make my blaster now also what upgrades do I need to do now that I have this engine in now. I already have a DG fatty pipe with a FMF silencer, tors delete and I mix 32.1 and stock carb as far as I know. I’m not sure if the person who had it befor me did anything to the carb. Any advice will be great thank you
