Holley 350 Ultra HP black on a 602

[bmodracer]

Are there any changes that would help running these on a 602? I've heard of guys adjusting the floats, setting idle mixture screws and idle RPM and racing them. Its hard for me to believe these would work perfect straight out of the box.
thanks!!!

Don't believe it. They're under-informed. Any carb can sort of work but they are down on power from good ones. They won't respond as well either. It's better to buy a good one the first time than to buy twice, especially on a sealed engine where bolt-on parts are the advantage. The people that think the out of the box carb is "perfect" have never dyno tested against a JDR, Willy's, Stealth etc. Try that sometime and see what order they fall into especially in tq numbers....
