Hi Chris...You can still have the babbitt bearings with full oil pressure...I used a S/V 8...21 stud oil pump with a few mods...you have to drill the block on the valve side..requires drilling through to the main bearings x 3 and connecting them to the outlet of the oil pump with fittings and copper tube..should give about 15 lbs pressure when hot...I didn't cross drill the crank as its expensive and not necessary if you not raceing...I change my pick up dippers and used Buick ...on the rod ends....Just dont thrash it and you will have a lot of early hotrod memories..Wish I didn't sell mine......Doug...

"dont know what happened to the previous post..just posted before I could finish"

 

Great looking car, are you sure the intake is a RAJO and not a ROOF? It may have RR or R&R stamped on cast on it.

 

The37kid,

You may be right about the intake used. I haven' got the roadster yet so I'll take a look when Customs are good enough to give her to me. The previous owner described the intake used as a RAJO?

 

May I add an eye witness account of the performance of a Model A when it was a brand new car?

This from Fifty Years With Motor Cars by A F C Hillstead. He was the first salesman the Bentley company had, and one of the attractions of auto sales was the opportunity to drive many different kinds of cars. He stated in the book that he drove more than forty makes of American cars alone, when American cars were not too common in England.

"In the summer of 1930 I had to visit a slate quarry in Haute Savoie and, with a co-director, duly set off in a 14 hp Ford; one of the series that followed the immortal Model T. It was hardly the ideal motor car for such a long run, but an eye opener from the point of view of cheap reliability. The comfortable cruising speed was no more than 50 mph , but this she would keep up for mile upon mile with never a complaint from the engine.It gave one the impression of everlasting solidity which is a curious description to give any motor car."

Ford took great pains over the balance of the Model A engine. Road speed were higher, Chev had a six cylinder and Plymouth was coming out with Floating Power. The old "Tin Lizzie" was no longer good enough.

Most Model As have been rebuilt with pistons heavier than they should be which spoils the balance of the engine and makes them vibrate and run rough at much lower speeds than they did when new.

 

Thanks for all the posts and great advice. Finally got the all clear from the Feds here in Melbourne Australia to pick up the roadster which landed all the way from California 4 weeks ago. They had flagged the container the Rod was in for some reason and held the shipment up for a month while they moved like molasses to process the cars.....geez!

Anyway, to the seller credit and to my great relief the roadster is as good as I dreamed it would be. Runs and sounds fantastic! That little banger has the nastiest sound and hops along very well. I've included some pix taken at my place. Thanks again for the words of encouragement and advice, and thanks again to 21stud for being such a stand up guy!

Chris.

 

Hi Chris...It looks great ... I'll bet your heart was racing when you first to it for a spin..you will get a lot of enjoyable hours of hot roding out of it...Doug

 

Doug have you got any pictures of pressurizing a model a engine? I've seen some other pictures and it doesn't look terribly difficult to do but the more the better.

I plan to run a KONG oil filter on mine along with hopefully pressurizing it.

 

Man that car is so cool. I remember when it was for sale and wished I didn't already have a banger powered roadster, don't need two of them.

My banger flies! This summer I was able to get it up to 90 before I had to back off as well. I was worried the coppers were going to see me as they hide out where I opened it up. I had been driving my car around for the last few years with a bad wheel, so I had never had it over 60 before this summer. I also have had two running engines in my garage waiting to go in my car in case I was unhappy with my bangers performance. A 49 Caddy motor and a worked Flatty. Engines are still on the garage floor! Slated for other future car builds. I also had a bad charging problem that almost caused me a few times to pull the banger. Glad I got it sorted and didn't.

Nothing like the sound of a worked banger!!! I love my 39 trans and 36 rear too. Someday I'll put my Columbia and Lincoln gears in.


Enjoy that car!

 

Wonder what he'd have thought of a proper 24HP Banger? The 14s were a small-bore version of about 2 litres because of the excessive tax rate on cars over here at the time.

 

Hey Chris, glad you posted!

I was following this and kept wondering if it ever showed up. Beauty of a car and great that it met your expectations. Njoy!

 

You will really like and it is a very cool car.

 

Fellas the car is a real peach....and err, guess what, its REAL roadster weather here now and will be for at least another 4-5 months.

KRAZY !!

Best head out to Johns R&C then tomorrow night huh....

 

Here are a couple of shots of your new car at the 2010 GNRS

 

Dirtyest Devil, glad to hear that you're still running the banger even when you have the Cad and flattie V8 in sight tempting you. 64crump thanks for the killer pix of the roadster. And Morac41 thanks for the words of encouragement amigo!

 

Any pictures of how you adapted the '39 trans?

 

Don't know what DD did, but I think you can install the '39 gearset and shifter in the B trans case, in the same way as fitting them in an early V8 case.

 

I'm away with the family at the moment but I can take some photos underneather the roadster to show the adaptor that mates up the '34 V8 3 speed toploader to the motor when I get back home.

 

Thats one hellava beautiful car, will it be at Chopped this year???

 

Wow, I just about shit a brick when I saw your pics. I have a '30 model A coupe with a hopped up banger and a '48 Fleetline too! You have great taste my man!

 

I've heard that the four cylinder and v8 were the same gears but obviously the four cylinder is a direct bolt on to the model a / b engines. In saying that, an original four cylinder trans case over here is just about nonexistant. If it were that simple i'd of done it already

Thanks mate that'd be awesome!

 

So how fast does it go?

Here are two. Both are OHV conversions. The Rail is an Alky car. Fun times!

I might've missed something; but I don't see where any of us have told A BONED about the monthly "Banger" meet thread here on the HAMB. There's a lot of helpful chatter over there.

One thing else no one has mentioned is: The value of a harmonic damper on the nose of an A or B crank. Over 2500 to 3000 rpm there are some regimens that, if not dampened, can break your crank. The break is usually in the vicinity of the rear main. Mine was at the flange. It happened in a race where, after running up to 5000 rpm for a number of laps, I was so far ahead of my nearest competitor that I backed off. Three turns later, the crank broke.

The current Banger thread is :

Yeah man for sure!
Might have to get a top for the roadster before the Chopped weekend. It seems to rain every year!

 

Old Dawg is right about the need for a crank damper prolonging the life of a carnk, but the breakage at the rear has other causes too. "C" cranks are the worst for this as they have less metal holding the flange on, also the flange 'nods' up and down with each power pulse which eventually causes breakage, plus of course that is where all the power has to drive through to get to the flywheel, etc.

 

Absolutely Jim! Like I said, I've broken a crank at the flange (as well as one at the rear main). As you, and others of us know, when modifying any passenger car engine (for that matter, any engine); the build starts at the "foundation". The lower end.

I think if a guy doesn't have a good sound crank to start with; he should look at the many after market cranks.

 

This may be the adapter your talkin about. 28-9 A block to 39" toploader. From Clings in Arizona.
