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) tk

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

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
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.

No going for a shorter stroke to reduce piston speed. Will increase the engine speed to make up for the loss of stroke. |
