I am new to this forum so I hope I’m posting in the right spot. I recently rebuilt my 300ex with all the goodies. It has a 330bbk kibble white +1 intake valves and springs ported and polished hot cam amr rev box and a 400ex carb. There seems to be a very loud tick coming from the top end. It is louder on the cam chain side. It does not tick at idle only when revving. What could it be? Also what’s a good starting point for jetting this beast? Lastly why is it that past about quarter throttle it sounds like it’s at full throttle. It goes from nice idle to bassicly screaming
