Okay, Moparts, I'm on the fence picking a carb for the wife's '68 New Yorker.

Here's the details
• Fresh 440 .030 over
• 9.0:1 compression
• Comp Cams XE250 - http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=704&sb=0
• Stock Intake Manifold
• HP exhaust manifold w/duals
• MPP Electronic Ignition
• 2.76 axle ratio
• 727 w/12” convertor

Would you bolt on an Edelbrock 600 or 750 performer?

This is 4000+lbs. cruiser/road trip machine

Thanks.
