5 Main bearing Model A block

[George Miller]

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.

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

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)

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.

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

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

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

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!

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

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.

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.
