SOURCE: Please explain the differences between a 351C, 351M, 400

The 400 engine was made starting in 1971 and the 351M was made starting in 1975. The 400 engine had a higher deck height so its intake manifold was wider and deeper than the 351 series. This was the result of the longer stroke in the 400 engine and where it gained the 50 cubic inches over the 351.

The heads are interchangeable with the difference being a slight difference in combustion area of the 2 barrel head, but of no difference in mounting the heads. I would think the valve covers should work for you You may just want to lay the valve cover gasket over the old valve covers to assure yourself they will fit.

Because of additional pollution restrictions the 400 series was changed to the 351C which used the stronger 400 crank and pistons but reduced the stroke back to the original 351. At that point the 351C and 351M were both made in Ceveland but the 351C carried the stronger parts. The M designation was to indicate a Michigan Casting motor, the M was manufacturered in 2 places and the 351C was made only in Cleveland.

The EGR is a power robber and soot creator. You do need Pollution equipment in some states. But if you live in a state where you don't, check the internet for kits to do away with it. Some intake manifolds need the "PORTS" to get exhaust flow to circulate gases for the EGR. Some Pollution equipment had "Air Pumps" to blend with the exhaust gases. I hope this helps you.

Testimonial: "Thanks for some straight answers. It was just odd to see the 351C seal on the valve covers only to find out it is as 400. Why didn't Ford say 400?"

I installed a holley 4 barrel carburetor in my 1983 buick regal , but it starts fine but won't idle ?


Check your vacuum hoses. Holley aftermarket may not have as many vacuum ports as OEM QuadraJets, and you may have a vacuum line that isn't plugged into anything...or you may have a vacuum leak around the carb base gasket. Also, does the Holley have an electric or manual choke? Is it connected?

1979 FoMoCo 4 Barrel carb. Getting good fuel flow and pressure to the carb. Engine will start and run for a few seconds then run out of fuel. New fuel pump has been installed. Can blow through gas...


is the needle opeoning on the float in the carb? The fuel bowl should be about half full all the time. As fuel pressure flows into the needle & seat, it fills the fuel bowl until the float pushes the needle into the eat. Sometimes the rubber tipped needle can stick in the seat.

Holley carb? Autolite carb? Holley 4160?

I have a 1984-85 holley 4 barrel and it has


Electric fuel pump most likely has too much pressure for the carb. AFAIK, the Holley 4150/60 & 4165/75 should each demand the usual 4.7-5.3 PSI (4.7 @ idle, 5.3 @ max RPMs), so even the Holley red pump would need some restriction from a regulator. If you want this to be adjusted to its best efficiency, you need to have a fuel pressure gauge installed temporarily, if not on the regulator like I have on my Scout II. FWIW, the regulator I have installed is the Mallory 4307M from CenturyPerformance.com, Summitracing.com, Jegs.com, etc.

http://www.malloryperformance.com/pdf/4307M.pdf

A bad Needle & Seat will do this also, or debris stuck between the Needle and the Seat. This is where light tapping on the bowl helps, but it's best to run the fuel out of the bowl a few times and then the volume flow, or quick filling of the bowl, should loosen up the debris.

You also could have set he fuel float too high. What model carb, the ones I mentioned above (AKA Holley Modular Carbs)? If so, then Holley's site has a tech center & instructions on setting the float(s). www.holley.com

Set the floats carefully and slowly/gradually. Make sure the lock screw is always loose enough before turning the adjustment nut. If you strip out the bowl's threads on an older carb, you'll beat hell finding a replacement. 1/12 turn = 1/32" of fuel height IIRC. You set the fuel level, with pump running (wrap a rag around the carb so gas doesn't leak onto the manifold!!!) so the fuel is just starting to dip out of the "peep-hole" in the side of the float. Removal of the peep/seep-hole screw/plug is necessary first. Clockwise rotation of the nut lowers fuel level IIRC and counter raises fuel level. Again, please check their website. Most people get discouraged when dealing with the Holley Modular Carbs, but they are the simplest and the best carbs on the market. Even if 30+ years old.

I need to adjust a carberater and get the 4 barrel to start working


Most likely you have a Holley carb. You may have a 460 engine. If you have the carb with a big vacuum pot in front of the carb, then you have a RPM governor. The RPM governor will work against the 4 barrel.

The main mixture for the idle jets can be adjusted like any old style carb. You may have plastic caps over the idle screws but take them off. Then use a vacuum gauge on any intake fitting and proceed to read the vacuum level as you turn the mixture screws. You want the mixture to reach a maximum RPM, then evenly turn the screw in until the RPM drops slighty and then balance for smoothest idle.

After this step adjust curb idle and see if this helps when the 4 barrel kicks in. Holley has different springs for the vacuum actuated secondaries and they are color coded. If the carb is original it should be right, but if the carb is of unknown origin you can check the proper vacuum spring, main jet, power valve and so on in a good Holley book. The mechanical secondaries are also listed with clearances to hand adjust.

By adjusting the mixture screws you have set the engine to idle just below peak vacuum pressure. This means you should have more vacuum to work the secondaries.
