I have a line on a TQ 2146 carb. I have a 318 with a rpm air gap and eddy 800 now. I now the square bore won't work with the TQ. I also have a 408 with a Super Victor intake and a Holley 750 dp. Is a TQ a good choice, or a better choice. I thought they were higher cfm, but my brother told me only the aftermarket performer series were high cfm. Whaddya think?
