Hi Fellas,
Here is a picture and details of my mates Flatty. This was rebuilt early last year, and has now been fitted to a 36 2 door Slantback. I will post more pics of the build.



Flattie is a 99A block merc (1939) 3 3/16 bore which is now bored out 60 thou with full 8ba bottom end and new rods,isky cam with adjustable liffers and s/s 8ba valves and springs hardened seats,alloy heads.The full rotating assembly has been balanced.new style water pumps.mallory dissy and harmonic balancer adaptered to crank,high volume oil pump and block set up for bypass oil filter.

Looks very sharp, except for the alternator, I just cant get used to seeing those on flatties. Very detailed.

[hope]

I would like to know more about the fan adapter to the alternator. Like where is it available, or did you make it?

[Vic Piano]

That is a "Thing of Beauty"...

Love the engine, sorry, the alternator, not so much.

[Lawrie]

How does the alternator go bearing wise with the fan,the generators with the fan on had two tapered rollers to take the fan thrust.
As for a nice engine ,maybe Gavin the hotrodder can post a pic of his.

CT AV8 ....... Thanks

[bk53]

sweet little motor. thanks for the pulley idea.

Looks way out of place

I think you did a fine job. Thanks for sharing.

[Talkwrench]

Looks great , I don't mind the alternator.. It wont last long with the fan on it tho'..

Yea, it fits right in with the distributor, starter, balancer, etc...

Almost looks too beautiful to put under a hood!!!!

Good question, I was wondering about that too. Finally ended up going electric.

they should not make those things! I went on a maiden voyage in my friends 35 pick up with a fresh motor. their was a bad vibration about 45 to 50 mph. we though something was very wrong. drove back to his shop and I dropped the fan belt and the vibration went away. took off the fan and put the fan belt back on and everything is good. he is going to take off the alternator and put a generator back on

[Ken Arms]

So whats the solution if you want 12v and no electric fan? Ken

I sent off an original 6v generator and had it rebuilt and rewired for 12v, works great 35 amps.

[john in illinois]

Ken I am going to use 12V generator field coils and a NOS 12V regulator. I have a 39, I think, generator and fan.

I have read that you can use a 6V generator for 12V without changing the fields.

Pete, what is the story on the harmonic balancer? I knew they were available for 8BAs but that is the first one I've seen on a 59A.

Regarding the alternator, when you get the engine in the '36, the radiator hoses should go up each side of it. That provides a bit of camouflage for it. Your pics have it out in the open and that maybe a contributing factor as to why the nay sayers are on your case.

You have to use a small diameter light weight aluminum or plastic fan, preferably 6 blades, and it will work fine. I've run mine over 4 years with no vibration or problems. I know the purists may not agree with this approach, but it's more appealing than an electric fan in my opinion.

[G.M.]

That's the type of fan required to cool these engines. That impresses me more than the rest of the non necessary parts. G.M.

[Ken Arms]

Flat v8, where did you send your generator? Ken

[felix37]

I love it! and the Alt. is just fine! I run one too, and as I'm driving across country I can pick one up anywhere!

[Pete from OZ]

Hi Fellas,
Thanks very much for your comments and concerns.I will pass them on.

36tbird -Pete, what is the story on the harmonic balancer? I knew they were available for 8BAs but that is the first one I've seen on a 59A.

I believe he has done a little machining and mounted it backwards. I will let you know.This is Tim,s first Flatty build

Here is a picture of it sitting in the Chassis. It has a Toyota Supra 5 Speed adapted. Open drive , 36 Banjo. 40 Juice brakes,VH 44 brake booster. Buick Drums. Headers are from Flat Attack here in OZ.

Yes you can use a fun projects regulator .

You can but they need a smaller pulley which don't work with a alt. mounted fan at idle. Put in 24 volt stator and you can use a stock Ford pulley and it will charge at a slow idle. The stator is less than $25.00 Sorry but didn't see you started talking
generator but I will leave it posted as general information anyway. G.M.

[Rollingmenace]

nice looking motor.. any info on the air scoops on the top of those strombergs I knida like them

[thirt4]

I was told once that there is an outfit that makes an alternator inside the old style generator case.

Perhaps if that is true, it might be a consideration for keeping those with the purist eyes from catching on and still get the amps needed.
Just my thought...

Still a good looking engine...

Ken, I honestly don't remember his name, he is in WA, he sells on Ebay, does great work! I think I have his business card, I'll let you know. Or you could just check local auto electric shops, ask if they can & will work on generators, That is a crap shoot!
