..... in the '50's era hot rod.

 

 

Fuel injection

 

OR

 

a blower

 

 

?????

 

 

Answers are in.....What is now going on in 1:1 land, is a lot more current, FI powertrains in resto rods. 

 

But the Question was 50's Era hot rod...Answer would be neither!...A new intake and carbs was $$$, so that really didn't happen. Grab a Caddy ambulance motor from the boneyard...start thinking cheap and available....get the picture as Honest Charlie was just starting.

I just did some research and found that the flathead Ford started the 50's as the engine to have. Seen a picture of one with a 3-71 blower and what looked like two strombergs on top.

The 331 Caddy engine doubled the horsepower of the flathead and I seen pictures of 4 and 6 strombergs on them, even blowers.

Didn't see too many fuel injection pictures as streetability must have been bad.

The Olds Rocket was seen around the time of the Caddy.

 

Streetability is something affordable and driveable. If your car dies at every other stop light, I don't call that streetable.

Affordable would be just using mostly interchangable parts, like Merc cranks. You still can buy the cheaper stuff new.

 

I'm looking to build a model that would be era correct before the small block Chevy came out. Any tips on what other things to use or not to use.

Caddy or olds rocket for a "high dollar" build or a flathead with a couple of strombergs for a more run of the mill build

Look at this years AMBR winner...Ardun Flattie  B) .

 

Revell has one in the 50 ford PU..This would also be "exotic" for the day.....Flatties did rule  and whatever else you could find in the boneyard was fair game. 

 

What Body are you running?? A flathead ford would not work in a buford...or ??

25 T Chopped top from the two car kit.

 

Comes with the 430 Lincoln, but that's too new for the pre-small block era. I have a Caddy with 4 strombergs being built.

 

What about the chrome reverse wheels? Were they in that era? Baby moons?

Things were changing pretty quick. In 1949 when the Olds and Cad OHV V8s entered the market, they would have been rare and expensive in boneyards. By 1955 when the SBC was introduced, availability of both the earlier OHVs had lowered the boneyard prices considerably. The SBC didn't immediately displace the Olds and Caddy engines, and every year the early ones got cheaper.

 

A box-stock 1949 303 Olds was rated at 135HP.  The '49 Ford flathead was rated at just 100, and to get 135 out of it, a 35% increase, would have probably cost more in machine work and parts than a complete junkyard Olds. The flatheads are severely limited by their poor breathing, even with the trickest of heads (except for the Ardun and other OHV conversions, which were way beyond the financial reach of the average rodder) so the effects of camming and carburetion weren't as pronounced as they are on an OHV. In the event, the typical rodder could get a lot more streetable, reliable power out of a Cad or Olds on carbs than out of a blown flathead. (The blown flathead in the photo above, while probably using a cheap surplus GMC 3-71 blower from a military landing craft, also has water injection and would have to be running a pressure-retard ignition system...these are not 'typical'.)

 

Some guys held on to their flatheads because they were already built, or just because they were resistant to change. The smart rodders who were about gong fast realized early on that there would be no way for a flathead to keep up with a rodded OHV in the performance race, and they made the switch.

 

If you go back and read the tech articles in Hot Rod Mag of the period, you see the advantages of the OHVs catching on pretty fast, and the knowledgeable guys at the mag disseminating info on things like power-to-weight ratios, volumetric efficiency, camming vs carburetion, etc. The info was available and the leading-edge guys went OHV early.

 

What you build depends on a lot of decisions the owner of the represented car would have made, relative budget, year, etc., and simply how good an engineer, natural or degreed, he was.

Thank you guys.

 

Your being very helpful and myself (being too young) not seeing these cars in their day, I did not know for sure what they ran. To many rods today run new stuff and makes things hard to find what was original "back in the day".
