1956 sedan 223 to 292 swap

Hi, can I swap my 223 six to a 292 Y block with no issues, e.g. mounts, radiator, etc. or is it a bolt in and go venture? Thanks!

You can send Steve Fritz a PM or contact him with this phone number or email.
I sold him a '55 Ford with the 223 six and he converted to a 272 V8 three speed manual w/OD. I'm sure he knows all the details your looking for. He may comment here too.

you have to use v8 mounts.and rad.6 mounts look the same but will set your motor back.done lots of these.

The 6-cyl side motor mounts are different from the Y-block mounts, but you can get new motor mounts from some of the repro parts suppliers.
The radiator side mounting brackets on the 6 and 8 are different also, because the 6 is longer, so the radiator on the 6-cyl cars is thrust forward into that space you see at the top of the front air deflector. Also, the 6-cyl cars had a cutout in the front splash-pan for the radiator bottom tank.
You can keep all that stuff like it is and install a deeper fan-spacer between water pump pulley and fan so that the fan blade will be closer to the radiator.
Probably the biggest concern is the trans bell-housing and clutch. The 6-cyl bell-housing won't bolt to the y-block regardless of manual trans or Ford-o-matic.
You can use same starter motor and drive, but you will need to add the round rubber seal that goes at the back of the starter for the Y-block, also available from repro parts suppliers. As for the bell-housing, there may be a conversion plate available, otherwise you will need to get a Y-block bellhousing. If you have manual trans, you might want to look at your clutch size. In '56, Ford offered 9-1/2", 10" and 11" clutch sizes. I am pretty sure you have to get the y-block flywheel also, which will determine your clutch size (unless you wanna go drilling and tapping new holes for a larger clutch pressure plate and cover assembly). Same goes for the Ford-o-matic converter. The 6-cyl converter is smaller than the y-block converter and ring-gear.
Back in the old days, there were adaptor plates so that you didn't need to mess with swapping a bunch of transmission parts, but I don't know about now.

Thanks for the information! I just bought home a 56 272. Does anyone have a bellhousing for this engine? I need a flywheel too!

you can use the 6 flywheel but it only uses a 9 1/2 will do the job unless your really going to abuse it.the 272 will use a 10 inch if you find a flywheel.
