Whats the difference ? 4150 question !

Maybe the race series brawler carb, 950cfm, part#BR67202, on sale (save about $60) at summit,$537.26?
He did say he bought a race series.
To gto man, if you believe that it really flows 950( im not sure i do) i think it might be too much for a mild cam, stock head, stock displacement 440. Ported head 500, with a big solid , well......
You are correct on your part# and I did buy it for that sale price at summit. As for flow gotta be more than the 750, just don't know if any gain will be seen. Its a .030 440 rpm heads not quite stock.
