New block machining.

Now we were talking 3 main B cranks. I suppose that if you pony up enough money, they will make one off anything ?

Crower, on the other hand, says that they will make whatever crank you request...just to have the 'specs' available for what it is that you want.
I was thinking, that if enough guys said that they would step forward for a 5 main bearing... B sized crank, that I could see what Crower would charge.
But, hey, I concluded that that would be like 'herding cats' , eh

Not exactly correct. They make a crank with B mains and A rod bearings. I'm running one.

Yes, you are correct in that statement. If you re-read my statement you will notice that I do not state anything of the MAIN size on the crank with A rods.
My question to them about this situation, i.e.- B main size with A rods crank, is why would anyone pay that large amount of $$$$ for a crank that has the puny A rod sized pins Why not make a FULL sized B crank...mains and rods. No real response, except that that's what they make.

I am a member of the Model A touring club. We are spending a lot of money trying to make something out of the old blocks and trying to build a decent engine.

I would really like to have a GOOD reliable "A" based engine using new components and better design. 5 bearing engines would really help our cause. We should be able to run at a good speed reliably and the thing should last for ever.

The way it is now, it may not cost much more then what some of us are spending now for a "good" touring engine and we would have a really good engine with more power that we can run with confidence.

I think a "B" sized three main crank would be fine, and a lot easier to deal with. How about a block with oil pressure to the mains?

They already sell engines like that -- $2500. Chevy 350 crate engines.

An agent orange solution! Sir you should be punished

We poured 2 more blocks today along with 4 of my Cleveland blocks. I wasn't able to be around to see them poured or shaken out so I have to wait until Monday to see how the next couple came out. I was told that the Clevelands look just fine so I'm hopeful the A's are just as nice. Surely, if we can pour V8's the A can't be far behind. I was machining Clevelands all day today so I couldn't be there.

Hey Tod,
THANKS for the update, I was worried that you may have caught the flu ! YOU do have your flu shot,eh ? Can I send you some cough drops..licorice, cherry , Canadian club ?? Can't have you getting 'down at the mouth'....until my block is done

[Bill Stipe]

We do make 5 bearing cams but mostly for hill climbing and Bonneville.
If there is a call for them we will do more, most people don't use the fuel pump anyway.
We had a Integrex 300 but the costs were a little to much for me and we sold it to a company in Canada to make cross bow parts.
here is a picture of my T crankshaft.

sure makes my mouth water to see all that fine machining going on !!!

[CWPASADENA]

It sounds like I need to get my engine stand ready. Finished parts may definitely be a reality in the near future.

Today I was at the foundry while they shook out the 2 castings we poured Friday. The additions I made to make the B internal looked just great. I was anxious to get them both processed and in my hands to do some machining. But, I am only going to get one of them. The owner wanted to keep one and section it to be sure of what we have. Since he is casting these for free I couldn't really argue. So that leaves me with one to machine up. I will probably just use it to do all the fixturing and then machine it to be an A block. I can't wait to get started on that! So, we decided to order more cores and make some more. As this moves along I'm going to start making the 5x5 internals so that can get closer to reality also. Sorry this isn't going faster, but I do have to sleep, you know.

Tod,

good job so far, you are allowed to sleep some.....

I am not sure if I had mentioned this, on the cam bosses, (5x5) try to leave enough metal to run a larger cam. up to 1.80 dia

It appears to me that you are really making very good progress. I have been involved in manufacturing and I know it just takes time to get tooling together and you have to be sure the sections of the casting are all good etc, etc, etc.

I need to hurry up and get my engine stand ready for a new block.

Thanks for the up-date.

Yes, that has been brought up by someone, maybe you.

I am a SCAT dealer, and in talking with Brian about some things, I think it is feasible to probably have the pin journals machined to 1.874. They have several operations already programmed in and this is an area where they could change the program too.

When you say machined to a puny size, my personal opinion for the reason is two-fold. 1) ...the aftermarket 'A' Rod availability is great being offered by several producers. And, they are cheaper,. 2), that area is not really where the crankshafts tend to break which means the 1.499 size is quite adequate. The new 'A' Rods would likely be just as strong as a 'B' Rod.
