I'm working on this thing and am trying to sort it out. Engine seems to run out good but it seems to not be making as much power as it should. It has a Uremco remanfactured carb on it.

I suggested to the owner to let me drop a 95 E300 diesel engine and transmission in it.

How do I work through getting it to where it used to run?

Have you checked out engine compression?

I have an excellent 95 E300D motor and tranny available for a reasonable price.

240 or 300? Compression? Miles?

I thought they had a 270 in that vintage.

Most of the 60-s era Ford trucks either had the 240 or the 300's. A very limited number had the 170 CI.

The 300's had a often occurring problem with the intake/exhaust manifolds warping.

I had a '65 240 straight six. The grommet that held the PCV valve hardened with age/heat and leaked vacuum, which robbed the engine of power.

The 170 in my Falcon sat for about 25 years, and the unbeknownst to me the hydraulic lifters were dry and it wouldn't start. My friend came over and took out the distributor, put a screwdriver that was taped to a drill on the oil pump shaft and spun it for a few minutes. We had the valve cover off and as the lifters filled up you could see some of the valves start to open...after we put it back together it started up as if it were new (with a little bit of gratuitous smoke for the first few seconds ).

I don't know if they put solid lifters in the truck engines or anything, but it's worth checking. We spent a few days cranking that thing trying to figure out what was wrong.

The smaller Ford sixes of that era had a problem with the cylinder head cracking between the number one and number two cylinder. Number one and number two in this case being the first and second cylinders back from the front.

I think a compression check is in order.

The heads would usually crack and give you low power. The crack was not apparent until the head was cleaned and sometimes surfaced.

Get a timing light on it. Check that the ignition advance is still functional. Maybe you already have. I assume that you have cleared the possibility of a bad fuel filter as well?

LOL - heck, I've been driving it. Come to find out the tires/wheels are not stock or something causing speedo off. When the speedo says 55 mph you are actually going 65 mph. Truck runs out good and does not seem to use oil.

I will start getting into it over the next few days to see what is going on.

Are you saying you got pulled?

Had the 300 six back in the day. I wore the engine right out but the rings were still good. Truck burnt no oil but wear otherwise was so bad oil pressure was very low.

I've got speedo issues with my F-250's, too...because of larger than stock tires. One is off by about 7mph, and the other by 10mph. We usually stay within 5 of posted speed, or just go with the flow...no need to attract more attention to the lifted beasts. LOL
