Default Recently Acquired 50 Ford With A Merc Engine

First question: What oil filter to use in the canister?

Second: What is the oil replacement quantity in this engine?

Thanks in advance!

Test.

Have spent some quality time on the site reading about these flat head engines. Tried to search for the differences between the 8ba (or is it b8a?) and the 59ab. As described earlier, this car has a Merc engine (where it is to have the 4" stroke) also has the thin water pump pulley configuration.

Just really enjoy getting to know more about the engine and all the mods that can be done to these tried and true machines.

Thanks for your help in advance.

Test.

The Merc and Ford engines are exactly the same, except for the bolt on stuff, Intake, oil pan and a few other things including color. Unfortunately some people put Merc intakes and heads on their 239 engines expecting a performance improvement. The only real difference is the 4" cramk.

Howdy Test Osterone, and Everyone else! I'm certainly no engine expert but if you are curious about the crank... Same trick to find TDC on any given cylinder.

Couldn't an easy stroke test be to take a chopstick or ke-bob stick and put it down a handy empty spark plug hole, mark lowest and highest points when spinning engine BY HAND and bingo, a rough stroke measurement? Be sure to video it for us, don't shoot the stick across the garage or dent the underside of the hood. I always wear safety glasses. You might have to jiggle the stick a little as it moves up and down so it doesn't get crushed, but that's why you use something soft (no screwdrivers) and don't use power to turn the engine.

Just a thought, and congrats on the new car, I think that year is very sharp.

edit: Waitaminute! What is that silver thing parked next to your new baby? Looks like an 'I' car, ends with the letter I? Duh, on third look I noticed the banner. Color me green with envy.

The only thing you can measure through the spark plug hole on a Ford flathead is the exhaust valve lift. You have to either remove a head or the oil pan to measure stroke.

Yup, that's what I get fer thinkin' again. Of course the spark plug hole is not above the piston, goofball!

The biggest problem here is the distributor, regardless of the stroke. Swaping intake and carbs has ab affect on timing and these distributore don't work very well when everything is right.

Yep! and one with centrifugal advance as well. Maybe not as good as a good vac. advance but better than original.

Yes, you are right. It is one of those with an "I" ending Marque. This one is a 456 GT. 12 cylinder front engine 2+2 car. Not an in your face Ferrari, but one with some elegance and lots of go... In it's day, was the fastest production car in the world save for the F-40. Please excuse the Ford above the 456 GT....

Seems logical, but not practical in real life. Will simply believe it is the Merc variant of the Ford Flathead.....

Is this considered a "high rise" intake manifold? Or, is this the OE Merc intake manifold?

Really? Seeems to work well. Should it be a different configuration for even better performance?

How to tell if it is a Malory dist? From the discussions above, is this configuration not desirable?

What is the best distributor configuration for this application?

Guys,

Really appreciate your contribution to this thread and certainly for my education on all things "flathead!"

Again, many thanks for all of your comments as well as contributions and help on all the various applications for this most interesting platform.

Test.

The Merc intake I was relating to is the stock OEM one, it has a four bolt carb flange and bigger bore riser part (the bit twix the carb and the front and rear facing inlet tracts) not a "high rise"
The distributor, I was relating to the stock Loadamatic one, this is the stupid one.
I hadn't actually looked at your pic, just agreeing with Ron.
Should read all posts, my mistake.
yours appears to be a Mallory with centrifugal advance. These more often than not have the wrong advance curve from the factory, it uses a sbc Chevy curve. It'll run and to someone that hasnt driven a Flathead with the right ignition curve, will appear to work "ok". I can tell you for certain, if it has the wrong advance curve now, recalibrating the distributor with the right curve will make you smile, a lot. The difference can be huge. With higher compression like yours, a sbc curve can give getting on for twice the advance you need or want, hurts power a lot.
Centrifugal advance + vacuum advance will give you all you need. The vacuum advance will increase your mpg. Still gota be curved right though.
Nice car, yours appears to have an 8BA-8RT intake, not the Merc one.
Martin.

The consensus seems to be a modified GM or a modified Mallory with vacuum advance (like I am using) see here--
