Technical Cadillac flathead horsepower tricks

I had to buy a whole engine to get my set of exhaust manifolds.
I have never seen a set before or since.
I spent a fortune getting them cracks repaired and hot coating them.

 

Hey 46international<SCRIPT type=text/javascript> vbmenu_register("postmenu_3599577", true); </SCRIPT> , Id be very pleased to receive a copy also if possible.
Many thanks, Russ.

 

Show us some pics of your exhaust manifolds , I am shur we all would like to see too....

 

Could I also get in line for an email..?

 

I dont have access to the pic's right now, but i will refresh your memory with this link.

I will post the finished manifold pic's when I am home.

 

Here is sum info you might like

 

Nice info Rille, thanks alot for that.
It is all interesting.
Lets keep this thread up the top where it belongs.

 

Finally ,I found it !!! ....... Here is a pic of twin flathead Cadillac engines in a tank ...... but look real close ! ....... they have dual carbs intakes and those hard to find tank dual exhaust manifolds that everyone is looking for ..... So just to let people know there are 3 type's .. tank style , industrial style ... and the standard car type with the cross over..... but I have heard there is one more ?????? ....or I even hear that someone might make some new ones so we can run duals on are flattys without breaking the bank or looking for those parts which you just can find anymore .............we shall see .......injoy

 

Some great posts here!

For the crank girdle, i like Peddro's idea of longer studs, and tying the mains together that way, and advoiding a line bore. Sure would like to see some drawings!

Steve, it was great talking to you the other day- thanks for taking the time! When you find that someone to make the cheap duals, give me a call.

There are three ways that i know to get relatively cheap duals. 1.) is you use a passenger side exhaust off of a 75-85 series car, it is a mirror image of the normal drivers side. You then can take the duals out of the crossover ports.
2) the 75-85 series dumped out the drivers side front, so you can use the drivers side, and have duals out of the front of the motor. Pretty ugly, i think.
3) the 1936 322 exhaust came out the passenger rear. Use that, and use your normal passenger side on the drivers side. It's very easy, you only have to move, or remove an alignment pin. Works good if you have room enough next to your steering.

 

VOTE !
Who would be interested in a 6 carb intake ? ...or... 8 stack fuel injection ?.....for flatty Caddy .. of course !

comence with the chatter ...........

 

Not sure if anyone of us with these beauties would not be interested... I don't know if that made sense, the short version is "I am interested"

By the way for those who have not met me in this tight knit Caddy Flatty community, My name is Kevin and I am building a 28 sedan with a 47 caddy in it.

 

Steve, my first vote would be the fuelie, then the sixpakck. Of course, if i don't get laid off, i'd probably find a way to have both!

I believe, that if more aftermarket parts were available, we would probably see more of these motors being built. One thing i've noticed here is, it seems these motors may be more popular outside of the U.S.A. than in it.

 

hi steve!
cool picture for sure..without doubt this is the later called frank burrell dual intake. he was head dynotester for cadillac during the wwII. he later bought the pattern, wich his son barry now use to make these beautifull intake in.
i know i have shown these before, but here's the brochure from burrell...

I had a flat head caddy in a 32 phaeton in 1940-41, Dual 97's on a tube manifold. Made the mistake of taking 1/8" off the heads and running it. Head blew into the water jacked, turned out it had already had 1/8" off the head.
New set of heads cost me $15 and $10 to take an 1/8" off of them.

Used to break the rear ends of the 32 axles.

But it was interesting to drive around with 3-4 other kids in and lighting the rear wheels in front of the drive ins.

cool story traderjack...tell us more! any pics!?

Hey Buddy you are a comedian, I bet the passenger did not think much of it.
This thread is like taking truth serum, all the juicy cadflat facts are coming out.

 

Well Rille, I guess my manifolds are the industrial version, but should do the trick for me for now. I note the fact that the generators have been spun around to make room for the Burrell intake manifold.

I am still getting around to posting some pic's of coated manifold, probably tomorrow so I can help keep this thread to the top where it belongs.

 

No , its not because of the burrell intake that they had to turn the generators around .. it was because the generators are so huge and also on the bottom of the tank manifolds there is a small driveshaft coming from the nose of the generators going underneth the manifold to drive even more equipment ..... look close on the new pic , Steve

 

On my '37 model 70 the exhaust exits on the pass side at the rear. If this helps any. Also why not just fab up some manifolds? cant be that hard. Cut a flange weld on some pipe add the stand that the hold down clamp hits. should be easier than all of the machine work that is being talked about. no?
Just an idea.

 

That is the 1st time I have noticed the drive shafts under the intake.
What do they drive, I am assuming hydraulics, I guess that also explains the heavy duty belts up front then.

 

Here are the manifold pic's as promised as you can see they have seen better times but I just think of them as being light weight.
I wanted to coat them the same as the T bars, but I was told all the imperfections would make them look like crap.
So this is what I ended up with.

Sorry about the quality of the background, you can see the smooth areas where the crack repairs were done.
I had a 10 & 6 inch long crack on one side and a Vee shaped crack on the center port outlet on the other, I was wondering if I should have bothered at all with repairing them. I guess no as long as they hold together it will have been worth it, but I definitely not need to find any more crack in them for a very long time or they may end up taking their 1st flying lesson.

 

The drive shafts that run under the intake manifolds drives a huge fan infront of a rad behind the engines ....

 

Russ, thank you.

Here's a couple of interesting documents, courtesy of Thomas Kidd.

This is some great info, guy's, let's keep this thread going!
Good to see some flathead Ford guys getting involved!

 

Thanks Buddy.
Yes we are doing well with this thread.

 

Tom, thanks for the info! I'll post it for you.

Keep it coming, guys.

 

KEVIN, I LIKE THE SITE YOU STARTED ON THESE MOTORS, AND YOUR BUILD. I KNOW IT'S IN YOUR SIGNATURE, BUT I'M GOING TO RECOMMEND IT AND POST IT HERE. NICE JOB!

Sure that is no problem.

Here is the site

http://www.designrodeo.com

and just as I wrote on the site, I made it mainly to keep my own thoughts in order and let a few of my friends see what I was up too. I will be sure to update it more info as I have not keep it up to date.

On a happy note, I got the rear two pistons out of my block, and they slide right out (the rest to follow as time permits). Things are going pretty smoothly. Just wish I had more time to work on it, just like everyone else on here I bet.

 

i voted fuel injection.

How about everyone else?

 

Injection sounds interesting, but I am locked in with my Burrell intake for now.
I am still interested to know and read about it if anybody has info.

 

I spoke with Maddog Parts in FL a couple of years back when I 1st got hooked on these monsters and they offered me custom made pistons at $80 each.
Expensive when multiplied by 8, but stilled tempting for the right project.
