No, the 600 will not flood a stock 305. I am using a Holley 650 4-barrel (Model 4175, 80555S) on my 1984 305cid LG4. This carb is a Q-jet replacement, with 6 vacuum ports, electric choke and vacuum secondaries. The car runs perfectly with this carb although my fuel useage has increased since it was installed. However, that may be due more to my heavy foot than the carburetor. You can use the Carb Selector wizard on Holley's website (www.holley.com) to select an appropriate carburetor. The wizard said I should use the 570CFM, but that model does not have all the vacuum ports required for an emissions legal 305.

Mercurys were equipped with Autolite 4100, if a 4-barrel, or the Autolite 2100 if a 2-barrel. The Autolite 4100 is one of the finest carbs ever made. It was designed by Holley and is a square-bore carb similar to the HOlley 4150.

A holley carb can range in price from as low as $100 up to as much as $750 depending on the specifications of what the individual is looking for, and where they are looking.
for a start a holley needs tuning nearly every week. the 390 did not have a holley as standard, but the holley carb is a cheap replacement. find a mechanic that knows how to tune a holley and that may fix the problem. holley carbs are good on race cars ,especially when there is time between races to retune them.
