Where does the Ranger XLT fit in 74 model line. In 1973-1977, the Ranger XLT was the top of the line. In 1979 the Lariat was added as an upgrade over the XLT. In 1974 it was Custom, Ranger, Ranger XLT. As usual the Explorer package was available but did not "fit" into the line, it incorporated one of the trim levels with other options. The Explorer was actually a precursor to the current "Special Value Packages" or whatever Ford calls them these days. _ _| ~~.

There's even an article in the latest issue of "Ford Truckin'" magazine on how to put a new wiring harness (from Bob's) in a 56 F100.

I have several questions about this carb. I turned the air cleaner cover over, to allow more air flow into the carb, I want to put a K&N Air Filter on it sometime. Anyway yesterday, air cleaner cover turned over, I noticed two things. One it took a lot more fuel to get to work, it seemed like it took twice as much fuel to get to work and back home. Second, while under heavy acceleration, the engine seemed to bog down until I lifted my foot off the accelerator pedal some. Actually I found that if I would only push the pedal about 1/4 to 1/2 way down to the floor the engine would jump to life and go. If I floored it, the engine bogged down until I lifted the pedal far enough to find that sweet spot. I know I need to adjust some things on the carb, but where should I start? Accelerator pump travel, check the secondaries to see if they are functioning? Any words of wisdom out there in Ford Truck land?? The last time I dealt with a Holley Carb was 10 or 11 years ago.

It turned out to be the speedometer gear located on the shaft inside the transmission. I had to disassemble the back end of the transmission to replace it. Of all the stupid things the HARD to replace gear was plastic while the little gear on the end of the cable (easy to replace) was iron. It's now the pther w ay around and my speedo works great. You didn't mention what kind of tranmission your running, mine is a 4 speed granny gear, T-15. (I'm pretty sure it's a T-15, I don't feel like crawling under there right now) Remove the end of the spedo cable from the transmission and look in there with a flash light, if the gear looks chewed up, or dished out it's probably the culprit. You may get lucky and find that the easy to replace gear is bad.

Actually What kind of air cleaner, stock or after market? After turning it over what shape did it have relative to the carb intake horn and does the choke horn stick up above the floor of the air cleaner? Did it act up before you turned the air cleaner over? Sounds like you interfered with the flow by turning it over. Most performance air cleaner floors taper up to the horn with a rounded lip or rim which blends into the venturi. They recommend that it you run without an aircleaner you at least leave the bottom on the carb for this purpose. I don't fully understand the dynamics but know that with the exception of stacks for full out drag racing this is usually the case. -- Gary Peters -- (Mine)78 F-150, 2wd, 460, C-6 (Mine)78 Bronco, 4wd, 351M, Np 435, Np 205, 33's (Daughter's)92 Tempo (Daughter's)92 T-Bird (Wife's)94 T-Bird (Son's)90 F-150, I6 (Son's)76 Blue Bird School bus All mine to work on, maintain etc.. ------------------------------ Date: Tue, 05 Aug 1997 17:21:44 -0500 From: KEVIN To: fordtrucks Subject: can someone tell me my options?

You can step up one number jet size on your Holley and see if that helps. Shouldn't have to go more than 2 jet sizes richer. Pull your spark plugs to get a reading on the lean vs. rich status. Black plugs (rich), white (lean), dark tan means the mixture is just right. Chiltons has some good color plug photos for reading plugs. Someone else here can probably tell you more about changing jets on a Holley than I can. Your distributor hookup --- It may only use ported vacuum from the carb instead of full vacuum. With a ported vacuum port (above the the throttle plate on the carb) you should see zero vacuum at the port at idle. Full vacuum off of another port should show around 17-18 inches at idle. Depends on what type of carb your running as to how much vacuum it needs or uses at idle and cruise. I would hazard a guess that your carb uses the ported vacuum off of the carb going to the distributor. I added Accel plug wires to my truck and it solved about 95% of my pinging problems. (8mm Super Stock spiral wound, about $28). New Accel rotor cap and rotor too. How old are your plug wires? ALL of my books say that the EGR valve helps reduce pinging. This is because the reintroduction of exhaust gases to be reburned lowers the combustion chamber temps up to a whopping 2500 degrees. Without exception every Ford book I own says make sure the EGR valve is functioning and installed or you could end up with pinging. The Holley should have an EGR vacuum port and a Spark port for the distributor. Sometimes one way check valves and vacuum delay valves are used as well as Thermal Vacuum Switches to control when the vacuum is allowed to reach the device it is controlling. Ford calls the thermal vacuum switches, PVS. The EGR PVS should be a two port thermal vacuum switch mounted near or on the thermostat housing. There might also be a three port thermal vacuum switch on the thermostat housing. The middle port goes to the distributor, top port to the intake manifold vacuum source and the bottom port to the ported vacuum port on the carb. Decent vacuum diagrams seem to be very tough to come by. If you have a MOTOR manual or access to one at a library they may have what your are looking for. MOTOR also has a web site and may send you one, free for the asking. They tried to help me. Only other thing I can thing of is using a new ignition coil. Weak ignition can cause bad pinging.

With that much > torque, you don't need such a high stall speed. I'm running 591 flbs at 4500 RPM and I run a 2400 stall. Tork is not the deciding factor in choosing to or not to run a stall. the deciding factor is where is your power band if it comes in at an idle then you do not need a stall if it is coming in at 2 or 3000 the you do. what the stall is doing is making the engine get up into it's power band befor feeding power to the wheels. It makes it seem as though it hesitates and it does; but it helps if you are towing because it is not as hard on your drive train if the engine gets in it's power band befor getting into a strain. We racers get the advantage by brake torking, hold down the brake and bring it up to 2 or 3000 RPM then turn it loose and it'll launch like a rocket.

Mine runs 21 BTDC start and 43 BTDC full. I was attempting to say a mild above advance timing and a small inexpensive single grind cam would satisfy most folks craving for power and give a little economy. Folks be careful what you run out and buy. There are some heavy preformance people on the list and when you start talking horse power it makes the blood boil and the hobbiest gets excited and wants more. When you start building horse power the engine is just the start to do it justice you have to build a strong trany a good rear end and then start worring about putting it to the ground which intails suspension mods. My advise to the fellow that is attempting to build an every day hobby truck is shoot for 300 to 350 horse power using machine work and stock parts. If you do this any good auto machine shop can help you and your funds will go alot further. 300 to 350 horse will give a good seat of the pants pull and beat most comaro's and mustangs from the light.

Also as the valve opens it releases pressure around it so it only blocks the hole when closed and the second it begins to open pressure is released in such a manner that it actually helps the valve open this is why a triple angle grind on the valves is so popular. If you are bending push rods your valve train geometry is off probably due to having the heads milled the push rods are probably to long (it does'nt take much).

It makes it Seems like so many of us are trying to get two extremes from our trucks. On the one hand we want gobs of torque at the bottom for towing or climbing hills but we want to blow all those vettes in the weeds at the top too and It aint likely to happen without some serious sacrifices either to drivability or economy or putting two engines in our trucks. High stall converters might give us low speed drivability and torque but at what cost? Takes more rpm to do the job which translates into more fuel and more engine wear and produces more heat in the....
