How much HP does the 323 make? You can't make HP without air and fuel regardless of CI.
The dyno said 475, but that was without the accessories I am running on it.
A 650 carb will feed 475 hp. If you have that engine on a dyno with a mass air flow setup I bet it isn't using more than 650 cfm. That tells me that something was wrong with your 750 carb.
You have to look at RPM also.. as the RPM goes up you need
to move more air... I use my header program to figure the
air flow at max RPM... its the same program you use Andy
