Holley 850




The fuel curve on a stock 850 will be pretty close for you....

The fuel curve on a 950 is generally pig fat on the lower end for a 440.

If you have a AFR gauge and time to tinker a 950 might be OK...but you will have to invest some time in tinkering with it.

Throttle response a hair better with a 950 over the 850 though.



This about sums it up IMO. However, I'm curious, is there something that the 950 is not pig fat on in in low rpm and transition?

The 950 will be similar to the 750 for response, once the IFR is adjusted.
