Hey, gotta ask a favor, could someone post pictures (or direct me to them) of a 240/300 engine from all angles? Working from almost a 30 year old memory of what all goes where and what I might be missing.
thanks!! (links to semi exploded views would be great too)

 

What year, what vehicle? The connections differ a lot from a 64-95? Plus need to know what tranny and extras are on the vehicle? If you get that info posted, someone will chime in with the info your looking for.\\\\

Wicked has some good pics in his thread right here. I'm sure some other people will be along shortly with more.

truck is a 67 F100, guy I bought it from advertised it as a 300, but the VIN says it came with a 240, I believe in 67 they were awful close to the same. It has 3 on the tree, manual steering, manual brakes (no booster) and no AC
thanks!

 

snwbdrny,
To verify engine ci you can check the stroke. The external view of the two engines are the same. Ford quit offering the 240 in pickups around 68 or 69. To find out for sure what you have, take a piece of Romex house wire and strip it to get the white neutral wire (leave the white insulation on the wire). You'll need a piece about a foot long and a blach marker pen. Disconnect the coil wire and/or battery. Pull the number one spark plug (better yet all the plugs). Rotate the engine by the crank pulley until you have #1 cylinder on TDC (check the timing mark on the pulley). Incert the wire into the plug hole and rotate engine until it hits the bottom of the stroke (you might have to rock the crank to get it as close to bottom as you can) and mark the wire at a fixed point on the engine for reference (edge of valve cover etc.). Rotate the engine until you are at TDC again and mark the wire at the same reference point. Measure the distance between the two marks. There is about a half inch difference between the 240 and 300 strokes. The 240 being shorter at about 3.5 inches (3.48 in I think). The 300 has an almost 4 in stroke (3.95 in ?). That'll tell you what engine you have. Post what you have and I'll get you some info that might help.

Ford offered the 240 until 77, a friend of mine has a 76 with a factory 240.
Both are identical externally.
Here's a couple pics of one set up for a 69:




The temp sender is on the other side under the exhaust.

 

thanks!! can you take one head on and one looking towards the carb?
appreciated

 

snwbdrny,
I stand corrected on the dates Jared. I was working on memory and that doesn't work real well anymore, Anyhow here is a link for Ford six casting numbers and such. It will not give you a 100 percent positive that it is a 240 because all one has to do is drop a 300 crank and rods in a 240 block and its a 300.

wouldnt you know it? I come up with more or less 3.75.... trying to figure out which way the angle would skew the results..

 

Here's one from my gallery-


I think 70 or 71 was the last year for a different head on the 240, prior to that they had their own head with a smaller chamber. Good for a little performance boost on the 300-

 

Pretty safe to say you have a 300.

 

The last year the 240 was available in F Series trucks and Econolines was 1974.

1965/74 F100/350's: The 240 came as standard equipment, every other engine was optional except on 1965/72 F100/250 Camper Specials, 1973/74 F350 Super Camper/Trailer Specials.

Thru 1980, the engine code is the 4th digit of the VIN.

240 I-6: 1965: J / 1966/74: A

300 I-6: B
-----------
The last year the 240 was available in Galaxie/LTD's was 1972.

The 300 was not offered in cars.
