Re: RTH - Crankshaft bearing sizes

The C69 engine has a rather uncommon bearing type. I guess that was the result of the change over to full insert bearings for the con rods and all. Canada did it first before Ford USA did but then...

Re: Really old gasoline question

The World would, combined with condense and possible dis-similar metal corrosion. Metals like to find there way back to the earth in the form of oxides. Highly oxidized gasoline helps some as well.

Re: block quandary

The bigger the engine gets, the more of a mover & shaker it will be. A lot depends on what you want to do with the car too. If a person wants a go fast car then that sets the build to get it that...

Re: 8 ba id

A person can learn a lot from motors like that. For one, you learn that Mercury Heads will fit any 8BA family block since they are all the same. Two, you learn that the truck cast iron half bell also...

Re: 1929 sport coupe

If the spring is correctly positioned, it is likely a worn spring. Sometimes they can be re-arched but you have to figure that there must be some fatigue or even a cracked leaf or two in the spring...

Re: Really old gasoline question

Old highly oxidized gasoline has a smell like varnish on steroids. If you get it on you, you will reek of it until it wears off. I'm not partial to that odor at all.

I like my 1956 Ford 850...

Re: Model T Sparkplugs

The plugs will likely fire whether they have a single coil with a distributor or the original 4-coils and a timer. The principle is similar but a single coil won't put out a shower of sparks like an...

Re: Model T Sparkplugs

I've seen the X plugs referred to as 425 and 525 depending on the year of manufacture but the 525 is likely the single piece type but same heat range. There is a lot of unknown history on the...

Re: Rear spring shackle

Something doesn't seem right with those figures since the fit would be too tight unless the bushing bore is reamed. The two parts should be close to each other in size. At least within a few...

Re: Model T Sparkplugs

I think the Champion X spark plugs made today are closer to the old Champion part number 25 and they are likely cooler than the old part number 30. Now days they just have the one plug.

Re: Model T Sparkplugs

Heat range is mostly about how fast a plug dissipates heat. The faster it does that then the colder the plug is. It is controlled by the design of the ceramic insulator that is inside the combustion...

Re: Name of fitting?

90 degree hose nipple or barb are likely still available from a few sources. The thread size (National Pipe Thread) and the hose size (ID) would be it's reference.

Re: 1949 overdrive

The later cars starting in 51 or so had no lock out switch at all. It's just a matter of connecting the two wires together and insulating them to do a bypass. I prefer having the switch functional...

Re: Sport Coupe to Cabriolet conversion

The Cabriolet cars have extensive wood framing that supports the sheet metal and doors. The sheet metal is just an outer skin. The wood frame was built to hold the body to be more rigid while the top...

Re: 35 transmission

The original 35 with the slant back tower is still a synchronized 2nd & high gear transmission. They work fine if in good condition. The later 39 synchro shifts easier but you can get used to...

Re: Sport Coupe to Cabriolet conversion

The largest difference is the Ford coup pillar compared to the Fordor style pillar with the covered fuel tank and hood with extended belt line.

I think it could be done using the same basic...

Re: 1939 Ford-Mercury door pillar

The Mercury cars are a different design than the Fords so there isn't a lot that crosses over in the sheet metal. Four door parts cars are more affordable than the more popular models so there is...

Re: 35 transmission

Just to add more info, a change of gears to the late type from 1939 up through the 48 for cars is not an uncommon thing but using the slant back tower would require some mods to get the 91A type...

Re: 8CM or EAB cam for 260" Merc?

Ford was looking for more torque for the Mercury and later for the Ford too. There is likely not much of a noticeable difference. The EAB cam was the replacement for both Ford 239 and Mercury 255...

Re: Who's removed the governor on a BW overdrive?
