I have a 600 cfm Edelbrock carb with a Weind Stealth intake on my 72 Comet. It has stock exhaust manifolds, dual exhaust, C4 transmission, Pertronix ignition module. 279 gears. New plugs and plug wires. It starts and runs fine. After warming up it has a strong gasoline smell and if you stomp down on it the engine bogs down. I believe this carb is to big for a stock 302 engine and am thinking of going to a smaller cfm Holly. I see on here that some are running the 600 cfm carb. is this on stock 302's.
it shouldnt bog it down that much. u may try adjusting it and see if that helps. i have a 600 edelbrock, weiand intake, stock exhaust manifold, standard tranny and msd ignition on a stock 5.0 in my '71 and all works great together
My Edelbrock 600 needed the floats adjusted before it worked right. One float was too high and the other was too low. After getting them set correctly it ran 100% better
Also check out your rods and springs. Make sure the springs are clean and "springy" and not corroded. Make sure the plungers above them are clean and smooth, and the bores they're in are clean and smooth. Rods should be clean and should be able to freely move up and down in the jets. Might want to hit them with a blast of carb cleaner. And of course make sure you have a sane rod/jet/spring combo. And ditto about the floats...
Might be manufacturing defects. For instance if you have a burr in the bores for those piston/plunger things attached to the rods, that would make them hang and dump fuel.
So was mine. I couldn't get it to run right is the reason I opened it up to check the floats. I cut a business card 1" wide to make a 'feeler gauge' To adjust the floats, invert the airhorn cover holding the airhorn gasket in place. There should be 7⁄16" between the airhorn gasket and the top of the outer end of the float. To adjust the float level, bend the float lever until the recommended level is attained. DO NOT press the needle into the seat when adjusting the float lever. Next, you should check the float drop. Hold the airhorn upright and let the floats hang down. There should be 15/16" to 1" between the airhorn gasket and the top of the outer end of the float. To adjust the float drop, bend the tab on the back until the recommended float drop is attained.
This is the first Edelbrock I have owned. Always Holley or Ford. I will try to adjust it per your instructions. If it dosent work I think I will try the Street Avenger. Thamks.
Be careful of the Street Avengers. I bought one and couldn't get a clean idle. It had a badly warped base plate. Turned it in for another and it was warped as well just not as bad. I got my money back and rebuilt an old 1850 I had. I think that Stealth is going to be a big large also. A performer 302 would be better IMHO I also have never seen a plug and play carb. Some are close out of the box but all will need some adjusting to make right. One reason I like Holley's. I have jets and cams to play with them but with an Edel. I would have to buy a $40 kit to adjust them clint
Clint, the stealth is a dual plane for a 302. I also have parts to build Holleys and ford carbs. I have never had an Edelbrock before. It just appears like the 600 cfm is to big for my engine. I was just thinking this might be my problem. Ron 72 GT
no the edelbrock is usually too rich out of the box. do the adjustment checks and error on the side of lean for the settings from their manual. other than that you should be good at sea level to 3k feet without a jet change...
I did not explain that right about the Stealth. I believe the runners are too large for the stock manifolds and smaller cam being used. I think the Performer will give it a lot more crisp performance. A Stealth will work great with headers and a larger cam. It'll work with what you have I just think the Performer is a better choice.
