8ba crank in A block
 

can this be done?? difficulties going to encounter?

Re: 8ba crank in A block
 

A 90 degree crank has been put in an A block before. All that can be said is, it ran.

Re: 8ba crank in A block
 

Are you taking about an early 221 CI flathead that has a big letter 'A' on the heads? Usually about a 39-41 vintage?

Re: 8ba crank in A block
 

Or, in the alternative, a Model "A" block.

(I added this because I was initially confused by Dale's post until I thought about it some.)

Re: 8ba crank in A block
 

Me too! My head was beginning to hurt trying to imagine all sorts of things (and reasons) to put one in a "Model A" block! Coop

Re: 8ba crank in A block
 

I'm glad I wasn't the only one confused.

Re: 8ba crank in A block
 

I'm also on the 'confused list'... And, really curious. Wishing Pete would elaborate a little, if indeed, an 8ba crank in an A block (and, I mean Model A). And, is this what Alan had in mind?

Re: 8ba crank in A block
 

I think a lot of relative new comers may think of a 59AB as a A block when there are several possibilities to describe a flathead. To begin with, in the Ford and Merc line they are either 221ci 21 stud or or 221ci and 239ci. 24stud blocks. To my knowledge the 24stud mains are the same diameter up to 53.

Re: 8ba crank in A block
 

yes I am referring to a 39/41 Ford V8 block commonly call an A block not a model a 4 cylinder as has been booted around

Re: 8ba crank in A block
 

It will go in with no problem. You'll have to bore the engine to 3 3/16 to fit the big end of the rod down the hole.

Re: 8ba crank in A block
 

In my mind, it was not called an 'A' block - more along the line that it is a 221 CI Ford engine with a 3 1/16 bore - with a variety of heads (some of which had the big letter 'A' on them). There were other heads that did not . . .

Re: 8ba crank in A block
 

Also, you will need to change the rear pot metal slinger/seal plates - to the later ones with the rope seals) - as the 39-41 blocks used an earlier slinger/labyrinth type of seal.

Re: 8ba crank in A block
 

have done this before but not in a long time, still have the pot metal slinger from joblot's reproductions. just need any know reminder, yes block was bore to 3 3/16. bored and stroked--sorry your mind id different than mine, as I always referred to this as an A block

Re: 8ba crank in A block
 

Which main bearings will he use?
Wayno

Re: 8ba crank in A block
 

I thought mains follow the block, not the crank. Could be wrong.

Re: 8ba crank in A block
 

Mains do follow the block

Re: 8ba crank in A block
 

"Commonly"? Where is a 59A block referred to commonly as an 'A' block? But what the heck, I've no doubt missed lots of things during my 67+ years in the hobby.

Re: 8ba crank in A block
 

81A for 38-40 221 with 24 studs. 99 or 99A for early 239. The 11A block was when they changed the castings. The 59 series also included the replacement 41A for 221 engines but many have the 59 casting mark as well.

The Big A heads were just the 81A heads. Prewar 24-stud 221 block pretty well says it all. When I think A and block put together, I think Model A 200 CID 4-cylinder block.

you guys need a new hobby

Re: 8ba crank in A block
 

So, if I understand correctly, you're suggesting that those of us that have taken the time & savvy to research, learn, write, speak and use the CORRECT/ACCEPTED terminology and nomenclature are actually the bozos that need to get off the pot and quit wasting YOUR time in THIS hobby? Coop

Re: 8ba crank in A block
 

I think there are a lot of magazine terms like tranny, potato, helmet and a few others that do not agree with original Ford parts nomenclature found in original reference books.

Re: 8ba crank in A block
 

You can call it "A" and you can call it "RAY", but don't call it shevrolay...

Re: 8ba crank in A block
 

Amen

Re: 8ba crank in A block
 

if you have collected that much information don't you think you need to spread it around without so much consternation? I have used what I have learned to further what LITTLE knowledge I have to a younger generation, I am helping a new generation learn about these old Fords, have a 40 year old building a 49 custom with a Merc flathead, I also am helping a 45 year old build a family owned 40 tudor--this is the car that the engine will be going in.. All I asked was for a reminder of problems and what I got was a lecture about nomenclature. Sorry but this is supposed to be a fun hobby not a challenge to ones area terminology

Re: 8ba crank in A block
 

Its Mother's Day . . . everybody relax a bit, celebrate the great Mom's of the world and maybe we can all be a little less judgmental. I'm going to try! LOL

Re: 8ba crank in A block
 

the only help I got, as I was reminded, came from Tim Ayers about the bearings, thanks Tim!

Re: 8ba crank in A block
 

I have to say that I'm with "DD Coopman" on this.

I do have to say that I was a little taken aback by the O/P's response to those trying to help him.:rolleyes:

Re: 8ba crank in A block
 

I am with Coop.

Wanting to stay neutral, I resisted but here it is. Playing around with suspension, tire size, cooling systems, what carburetor, etc. can be part of a hobby. When helping a younger guy get into an antique motor, bottom end with antique parts, there can be no room for error. If it ain't right, it won't float.

As far as magazine terms, that I sometimes find humorous, realize that a lot of the guys writing in the industry today ( no disrespect ) were not around when a days work required work
