5 Main bearing Model A block
 

Here is a picture of the junk block that I put 5 mains in for the cam and crank.
This is to go with the head that I made last summer.

Re: 5 Main bearing Model A block
 

Looking good! Did you make your main webs, --or are these some that Dan Price made up a few years ago?

Re: 5 Main bearing Model A block
 

so why is it junk
or...
is this just a proto type so you can figure out what you will need to do to a good block to make it work without messing up a good block
what kind of steel are you using for the inserts (extra mains)

Re: 5 Main bearing Model A block
 

also what crank are you using

Re: 5 Main bearing Model A block
 

No I made my own.

Re: 5 Main bearing Model A block
 

George,

Your taxing my head, Chevy ll crank, Chevy rear main. Built those for midgets back
in the 70's. Have a friend doing an A for land speed, 5 main AL girdle , one piece, custom crank. Send more photos!

Dudley

UH...I take that back, it's a V/8 crank!

Re: 5 Main bearing Model A block
 

And to think I've seen you call yourself an Ol' Country Boy .....

That's outstanding work, George. Good job!

Re: 5 Main bearing Model A block
 

The lifter guides are broken, I will be redoing them any way. I would rather save the good blocks, some one might need them for a stock engine down the road.

Re: 5 Main bearing Model A block
 

Not sure what crank and cam at this time. It will be some kind of chev, I think.

Re: 5 Main bearing Model A block
 

Well I was born in the country, USA MICH.

Re: 5 Main bearing Model A block
 

George, someday I am gonna have to come down there and bench race some with you.

Re: 5 Main bearing Model A block
 

When you get mine done, call me. Herm.

Re: 5 Main bearing Model A block
 

George : What kind of power are you hoping to get out of this engine when all is said and done?

Re: 5 Main bearing Model A block
 

I would like 1 hp per cubic inch. They done that many years ago, so I should be able to do it now.

Re: 5 Main bearing Model A block
 

http://model-a-ford.com/ROFL.gif Good reason there George!!



Why I had asked was Dan Price had cast up some saddles a few years ago and still had a couple of sets the last I checked. I almost bought a set until I found a 5-main girdle to use.

Another crank to consider is the Hercules crank out of a forklift engine. I think the bore spacing was pretty much the same and it gave a ¼"(??) stroke. Are you gonna make your own billet rods?


As far as getting 1 hp per cu in, Hudson pretty much was doing that with their 7X Flathead. I'd say that 1.25 --or even 1.5 hp per cu inch is very do-able with your combination!

Re: 5 Main bearing Model A block
 

Come on down. Do you still go to old maggie valley meet in the fall. We could meet there.

Re: 5 Main bearing Model A block
 

I will probably make my rods out of 7075. I have made some in the past.

Re: 5 Main bearing Model A block
 

This is a very interesting project! I like your style, dig in and do it! How do you plan to anchor those extra main bulkheads? They look welded in, will that be it? Are you going for a big stroke? Thanks for sharing this with everyone on the Barn.

Re: 5 Main bearing Model A block
 

Yes they are weld in also will be pinned, and the main studs go all the way through the block just like the original, except they will be studs.
No going for a shorter stroke to reduce piston speed. Will increase the engine speed to make up for the loss of stroke.

Re: 5 Main bearing Model A block
 

Did you not receive it this week, is the check in the mail.:p

Re: 5 Main bearing Model A block
 

What a beautiful job! With my machining talent and equipment I will just have to wait for Terry Burtz to come through.

Re: 5 Main bearing Model A block
 

That's interesting! (to say the least) Keep the updates coming, and THANKS for sharing.

Re: 5 Main bearing Model A block
 

DITTO!
Terry Burtz is to the 'machinist challenged' (US), as George is to himself!
Terry we are pulling for you...come on son, get it done..as we can't afford Georges' great work!! lol

Re: 5 Main bearing Model A block
 

The only ones that deliver here are, Yellow freight, U.P.S. and Darby Farkworts Camel train, I even looked under the entry room rug, and none have any record of delivery, I even checked with Santa, although he is still Mad about the imitation chocolate chips in the cookies, and the unstrained Goat milk, he was even unhappy about the New Playboy I left him, an he couldn't get back up the chimney. I will keep looking. thanks Herm.

Re: 5 Main bearing Model A block
 

If and when Burtz secures enough investors and pays them off and then works out all the bugs, George's great work may be the best deal ...

broken guide
 

How do you repair a broken guide. I have a block with a piece out in the upper 1/3 of the guide, and I thought it was junk?
Chuck

Re: broken guide
 

Chuck you could put in a sleeve. In my case I have to move them a little.

Re: 5 Main bearing Model A block
 

George,
Are you making it full oil pressure?

Thank you for the updates.

GW

Re: 5 Main bearing Model A block
 

Yes full pressure to mains, rods, cam shaft bearings.

Re: 5 Main bearing Model A block
 

Bored the block for 5 cam bearings, so I can run a Chev camshaft, that way I can run double valve springs, so we won't have floating valves.

Re: 5 Main bearing Model A block
 

Well, if 'George' would/is available to work his special talents on an engine for me: HEY GEORGE,IF SO, PLEASE PM ME! Knowing that this ain't gonna happen, I turn my thoughts/resources towards Terry Burtz.
I believe in Terrys' work on his new model A block/engine and will expect to obtain a couple asap! I've followed his stated intentions and work in making his(our)dream come true, from the start! I'm sure that he has had plenty of backers, including me, offer financial and moral support for his success! It's exciting to anticipate something of this magnitude for us...like feeling of Christmas as a kid. In this case...an ole kid:rolleyes:!!
I personally miss his participation on this site and sharing his tremendous skills...the way George does by posting, etc.:)

Re: 5 Main bearing Model A block
 

Are there any updates on these 2 projects?
They are awesome!!!

Re: 5 Main bearing Model A block
 

The Herc crank needs to be lengthened in the rear main area, some end for ended them and welded up a flange. Quite a project! George, you might want to think about RPM as flatheads aren't known to rev very high. A friend runs Bonneville, turned 150 in a lakester. He turns it 5500, that is as high as any flathead that I know of.

Re: 5 Main bearing Model A block
 

Great work, George. Something like this is a real interesting challenge.

But is 1ps per cu.inch really possible? I find it much.
However, where will you install the engine? Hopefully in a nice traditional Hot Rod.
Greetings Barney

Re: 5 Main bearing Model A block
 

I'm going to watch this one, very interesting stuff going on here.

Re: 5 Main bearing Model A block
 

The block has all 5 main bearing struts in. I have a chev V8 crank in there, but that will make a uneven fire engine. So it is on hold tell I find a crank to use.
The head is all done and runs very strong. Right now I;m using the head on my hill climb car.
I have been working on my 30 pickup that was a real barn find, from a friend in Mich.

Re: 5 Main bearing Model A block
 

With my over head, I think so.

Re: 5 Main bearing Model A block
 

Last I heard about Terry Burtz project is that he got a useable block casting. That was a couple months ago.

Re: 5 Main bearing Model A block
 

Awesome - congratulations.

Re: 5 Main bearing Model A block
 

What about a crank from one of the 2liter turbo engines from GM or VW? I don't know the cost or alignment issues but I'd assume it can handle the power as they are producing 135hp per liter.
