smaller inline 6
I just got a 74 F100 with an inline 6 and the guy said it is smaller than a 300. Would it be a 240?? How would the smaller 6 compare? I have a 77 with a 300 and really like it. Any info, hints, or tips for the engine are greatly appreciated!

Funny that you ask this. I've been uploading emission diagrams for the old inline to my site and I noticed that the only sixes Ford listed in their emission book (used in '73) were 240s. I know the 300 was around some 5-6 years before hand when the 240/300 BIG SIX were introduced. This is a good question for Dennis. I wouldn't be suprised if your '74 is a 240. The easiest for sure way to know is to pull the oil pan and check the casting number (located on outer diameter on one of the center throws) on the crank. 1L is a 240, all others are 300. Power wise, well...it's less cubes. It should rev up a lot faster than a 300, but have less low end.

Your truck definately is a 240 if it's a 6 and not a 300. Not much grunt, but the fuel mileage isn't too bad.
I know that the 240's were used in 73, because that's what my truck originaly had. It's my understanding the 240 was discontinued half way through 74, then it was the 300 only from then on for a 6.

I've been told that a 240 and 300 are the same block with a different crank and pistons. It would probably be a pretty low buck build to swap the crank and pistons in your 240 and stroke her up to a 300. It would probably be the cheapest engine around to gain 60 cubic inches if you wanted to.
I have a buddy of mine that has the big 6 in a 67 F100. He has a cam, some head work, an electronic distributor, header, aluminum intake, and holley 4 barrel. That thing will out run any 6 in town, and all most all the small blocks.
