Pretty sure that the belhousings are a different pattern. The 300 has` the same pattern as a 302, I think.

I have heard that the 289/ 302 had the same pattern as the small 6's. I got a cruisomatic 3spd auto ( I think it's short name is C3 ). Are the motor mounts the same?

Can I use the bellhousing for a '289-302 as they were offered with cruisomatics in the Mustangs and Falcons. Or is there another way, or any way to do it.

Yeah, I agree.
There was a guy in Saskatoon, Saskatchewan who used to run a 300 inline six around 1980 or so. He had sectioned some 351 Cleveland 4V heads and had them welded back up. Apparently all of the bolt-holes and coolant passages, etc all line right up. Ford's BOSS 300?

I think he named the car "Scrapper II" ... are there any other old Saskatchewanians in the group that remember that car?

That car was just crazy! I don't recall his times, but it was fast and consistant too.

Welcome to the group Matt. It's nice to see a young fellow with these interests.

Don

Dude, you best measure that 300 first. Ive stuffed a FE in a 67 b4, I dont think a 300 gonna fit. A 250 outta a Mavwreck or fairmont will fit.

BTW got a 4 bdl manifold for that 300 if ya fit it in.

300 is awful tall and long for that engine compartment, would take a lot of modification. I also think the bolt pattern is different.

If the automatic is original cruise-o-matic for that vehicle, it is probably an FX, I think small block V8 bolt pattern would fit but check with an expert like Kultulz or in the reference sites (can't find them right now -- but may be able to check later).

Don't want to discourage the 300, it is a great engine, but just be aware it will be a challenge.....

200 to 300

Something you might consider, is swapping a 250 Ford I-6 into your car. It is basically the same engine as your 200, with the exception of a slightly taller deck height and it also uses the 6 bolt SBF bell housing. Engine mounts are the same oh the 200 and 250.
While you would be giving up 50 cubes by going with the 250, you are also giving up about 100 or so lbs of weight.
The 250, is an undersquare engine, with a realistic max rpm range around 6000 RPM, for street use, but it is capable of putting out a bucketful of power up to that point.
As for speed goodies, I believe Offenhouser still makes the 3 single throat carb intake, for them, which is utilized by drilling two holes in the intake runner, under the carb pads on the intake setup.
You might also consider checking with Clifford Performance on cams and headers, as I know he does have them for the Falcon 6, as we used to call it.
Using the 300 will require fabricating or modifying engine mounts from a car or truck that once contained either a 240 or 300 I-6.
The 240/300 do use the same 6 bolt bellhousing as used with the 289/302.
One of the major problems you will run into with this swap is the oil pan.
Having helped drop a 300 into a 69 Mustang, one time, I know what a pain that is. I dont remember exactly what the guy did about the pan, whether he did his own fabrication or had one made.
You will also need to scavange accessory mounting brackets from a car or pickup that had the big 6 in it.
The Cruisomatic transmission is also known as the FMX, which has an iron center section with an aluminum bellhousing and tailshaft housing. Swapping bell housings is a simple matter on both the FMX and the C-4 since both bolt to the front of the transmission. You may well also have the C-3 transmission, which is a light weight version of the C-4 and may well not stand up to the power put to it by a larger engine. If the C-3 is what you have, best to junk it and put in a better trans. The C-3 and C-4 are both all aluminum housed transmissions.
