A Holley is a very tunable carb....but it's not the easiest to tune. It really needs to be adjusted and set up for each engine. Meaning jetting, secondary spring opening, power valve opening, even the fuel pump cam can be changed. For initial set up, get the timing on the car and the idle speed set up to keep the car running. The floats on most are also adjustable. If you don't have the clear site plug in the bowls you'll need to remove the screw in plug and adjust the float until it just barely trickles out the hole. To do so you need to loosen the large screw on the top of the bowl 1/2 to 1 turn then turn the large nut clockwise to lower fuel level counter clockwise to raise it. There are two idle mixture screws on the front sides of the carb. Turn those in until they are LIGHTLY seated then back out 1 1/2 turns. This will get you an initial setting. If you have a vacuum gauge hook it up to a vacuum port on the base plate of the carb. You'll want to turn those mixture screws to get the highest vacuum reading. Turn each one 1/4 at a time until you get the best reading. If you don't have a gauge listen to the engine. You will want the "fastest" and smoothest idle you can get by turning the mixture screws. Then adjust your main idle screw to your desired idle speed. You may even want to go through the mixture screws again if you had to lower the idle a lot. Last but not least, pick up a book on tuning a Holley. It took me a long time to get good at tuning one.

Will a Holley 600 Flood a stock 305Is it to big of a Carb?
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.

What should you set your timing at 92 goodwrench 350 stock heads 488 lift 292 duration edelbock performer intake holley 600 carb is carb big enough?
Probably start out at the manufacturers spec and increase a little at a time until best performance is achieved. The 600 should be fine for a mild 350, but a cam with that much duration will need an aftermarket convertor for an automatic. A four speed should work ok.
Does holly make a carb for a 1962 Cadillac Deville?
holley makes carbs for all vehicles. the manifold on the caddy is set up for the carter afb, which edelbrock used as a base for their carbs, so an edelbrock will bolt right on. this is the route i took with mine. you will probably have to get an adapter to set the holley up on the square bore of the old caddy intake. the adapter should be available wherever you get the carb. hope that helps.
