Holley causing "surging" @ idle - help with timing too... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put a used Holley on the 327 SBC and now it has a major surging idle (700- 2,000 RPM). Where do I start? Also it is so rich that truck is smoking like a chimney. Didn't do this with the Q-jet and old intake. Any good Holley tuners out there, it's undriveable at this point....thanks

Also, wha't the best timing to start with? Not looking for performance just a strong truck....
