Put new distruber in my 1975 ford 351 m I can get

SOURCE: backfiring and loss of power

'till you do some in depth testing of all systems, I'd place equal weight on every possibility. Make sure you cover the basics like fuel filter etc before getting crazy with it though. Also check cap. rotor, coil and wires. Idle cylinder pressure is different than that encountered when driving. This additional pressure will cause ignition spark to seek a better easier ground,(not the spark plugs where it should be going) causing missing under load.After checking , if you haven't found anything, its time to begin testing fuel pump pressures, modules and controls.
good luck

first of all you have no carb its fuel injected, at least you know you have spark, now do you have fuel pressure??, is the fuel pump working?/ if you have fuel and pressure then you have to check signal at the injectors, so if you have fuel pressure and a good injector pulse the next step is to check the injectors, this may require removal, good luck

A fairly straight forward answer provided by another... just pasted here... word of caution with his method... BE CAEFULL OF MOVING PARTS.. also disconnect the coil so you dont get bit :-)


You will need to know; firing order, #1 cylinder location, and have a assistant. Get a basic repair manual from library to look up these things. Remove #1 spark plug from engine. Place your thumb over the hole. Have assistant crank engine over until compression is felt on your thumb; this is close to TDC or top dead center. Grab onto belt and nudge engine over until timing pointer is aligned with O or TDC on engine dampner. This is near perfect TDC. Now take and insert distributor into engine so that the #1 spark plug wire terminal on the distributor cap aligns with the rotor inside distributor. If it does not pull up distributor and reinsert till it does. Tighten everything and it should fire right up. Now you can fine tune with a timing light.

Testimonial: "thank you"

common causes for back firing, low fuel pressure, or restricted injectors, breakdown of secondary ignition coil, internal ignition coil arching, or a dead spot in throttle position sensor.

SOURCE: Should I rebuild my Ford Bronco 351 Windsor Holly

In all my experience, if you know how to correctly tune a edelbrock then go with that, but, holley has outstanding carbs that can muster up to an output of 1,200hp. it would be much cheaper to et a rebuild kit from say, o'reillys, 20-45 dollars depending on which one you have.
I have a 1985 Bronco 351w 4x4, i just rebuilt my holley and she runs smooth
