i have a 521 in my pulling truck and right know i have a 930 carb and want to go to a 1050 dominator
The question is if i buy a 9375 dominator out off the box or spend more money and have someone build the carb to my engine will i tell much of a diffence in a truck pulling truck

My personal opinion is that most of the value in a custom carb is it's ability to work well at different rpm and throttle opening ranges.

As far as I know, pulling pretty much requires some finesse at the beginning of the pull..but then it's WOT the rest of the time? With that in mind, I think a shelf carb would work fine.

Built Carburetor

I feel that you would gain quite a bit from having a "built" carburetor done over a box stock Dominator. it is true that a really good carburetor will run better under part throttle and idle conditions but it will also run better at wide open. The reason is that the emulsion and fuel curve can be inproved greatly on the stock Dominator without any elaborate modifications, just good tuning.

A new 1050 Dominator package from Competition Carburetion is around $1000 give or take depending on options and that's a nice piece.

Wrong 1050 Dominator carb...

The 9375 is made and calibrated for a 2 four barrel set-up; althogh they can work just fine AFTER reworking whatever needs to be done in order to make it right for a single four barrel application..
However, the 8896 is calibrated for a single four barrel set-up and will work quite well "right out of the box".
