Okay thanks, a couple people have told me its

What do I need to figure out the right carb for my application? I've done the calculators & the 470×7000×.95÷3456= equation. Everything is telling me 1000-1050. Is this something I can only figure out on a dyno ? I guess I need more learning

Your parameters come out to [email protected]%VE but you don't know the VE at a given rpm. Our 589 dyno pull shows our 950HP with 1.375V and a billet 1.750 t/bore plate pulled 104.4%VE@5400rpm and was using 957cfm according to the calc, but its just a calc...at 6000rpm VE went down to 96.8% but was pulling 989cfm in theory.....at 6000rpm the carb pulled 2.0"Hg of vacuum, at 5400 it pulled 1.7hg. That carb made 695hp from 5500>6000, a 1050 Dominator was also tried which made only 3hp more and around 0.6hg, the carb could've been rubbish but we don't know.. a lot to get your head around I know and I'm only 98% with it myself. Every one will tell you an engine of that size should have an 1150 Dominator on it at least, not always the case, if we ran more rpm, had a better converter (4500+) and more cam perhaps, but this car is street/strip.
