Re: [Amc-list] modern six in an old-six hole

[Frank Swygert <farna@xxxxxxx>]

Some Ford guys, especially htose with mostly V-8 experience, confuse the 240 and 250. The 250 DOES have the SBF pattern bell. The 250 is 1.66" taller and around 1.50" wider than the 144-200, and the cam is higher in the block on the 250 (so timing chains are different). The wider block means the oil pan is different, and the pickup tube is different also. See http://www.fordsix.com/tech/engine/200_swap.php. 

In 1980 Ford revised the bell on the 200 to be similar, just the top two holes are different due to the lower deck height of the 200. The larger six (300 uses SBF pattern also) or a V-8 bell can be adapted though. See http://www.fordsix.com/tech/engine/bigbell.php

The 200 was made through 1983, I think the 250 was also but only found a listing as late as 1980 (75-80 for the 250, 65-83 for the 200, but only 80-83 for the "big bell" 200 -- with the earlier model you need the transmission too).

I keep hearing different things about the 250. It should have the same bell as the 240/300 and SBF, but others say it's a smaller pattern like the 144/170/200? The C4 in the IH is the heavy duty version with the light duty bell (like I did the 170 motor in place of the 300 in my '75 E150 years ago)
   Why would the 240 be under the hood of a Mustang? I figured it would be too long to fit? Maybe these are questions for the Fairlane forum I used to be on.
