Ooopppsss I am reposting this from the Street forum, I think it is better here 😅


Hi all you Y-block lovers! I'm new to this forum from Athens, Greece with my '54 Mercury Monterey driver. It has the original 239 with low mileage, manual with Overdrive, 6volt positive ground, the 2140 Teapot and, the ' temperamental' Load-O-Matic..

Before learning that need a SUN machine, way back I tried to adjust the spring weights and really messed it up. I found one in England but it came back and still is no good. I've always had problems and lately it misfires especially in the mid RPM range.


Here are my novice questions for your kind expert consideration:

1. Is there a way I can manually tune the springs without the SUN machine?

2. Are there reliable Load-O-Matic tuners in the states I can send it for proper tuning?my Load-O-Matic for tuning or I just forget about them?
3. Should I simply forget about it and go for a point unit with centrifugal weights like the ones used in the later Y-Block engines? And frankly I would like to keep it as buy now. I ( I can easily do Ted 's vacuum Teapot conversion I read about in this forum) know it quite well
4.
5. I am also open foran HEI distributor that looks like my original and can fit with the shaft length and tang coupling to the oil pump. However there is a question with the wiring of my overdrive's kick down switch wiring on the coil, because I tried the Pertronix unit it way back and it did not work.

That's it, thank you all in advance

Back on page 6 Aris said he took the 13 tooth gear off his NOS distributor and put the 14 tooth gear on.  I thought 239s and 256s had 13 tooth gears, '55 and later engines had 14 tooth.  If the distributor he took out of the engine  had 14 teeth, then he doesn't have a '54 engine.  Or a '55 or later camshaft has been installed, which is not a direct fit in '54 engines.  Maybe someone has put a '55 or later short block in his car.

There were two 1954 FYB engine series -

- the DEARBORN built 239CI which was the EBU BIG CAM ENGINE and had the 13T cam drive.

- the CLEVELAND built 239-256CI which were the SMALL CAM ENGINE(s) (EBV and EBY respectfully) and required     the 14T cam drive.

It most certainly is possible to improve performance with a LOM install, but the subject was SERVICE REPAIR, not SERVICE UPGRADE or MODIFICATION. The OP wants the car to run correctly in it's original assembly 



No need for a restoration. Did you see the under hood shot(s)? Which method is going to result in a more valuable car, the OEM system(s) or a resto-mod?

THANX! for finally coming to your point.

Kultulz, thanks for that information.  I never knew there were two different 239/256 series, I thought they were all the same.
