My combo is close yours and I have tried two different sets of carbs on my Weiand-1850(600) and 4224 (660 center squirters). The center squirters are faster and leave harder. I had to lean the idle circuit out on the 4224 but after that it was all good. I noticed all the hard core racers can spot them a mile away. I actually have both sets of carbs for sale if you are interested.



another vote for 660's
I have them on my 572 Inch hemi, the engine has manners like a 318 2 barrel, until you mash the pedal.
