1933 Roadster Special - new member needs help

Guest mawa

Recommended Posts

Hello there

some times ago I acquired a Pontiac 8 roadster in Argentina - a wonderful looking car:


The car was built from some parts (frame, radiator, engine) and imagination.

The Argentinian title shows year 1933, chassis# E-041448, engine# P-474560.

The only thing I could verify is the Pontiac engine number which is shown at the front left below the cylinder head gasket.

On top of the cylinder head are the numbers D 33 and 494901 or 484801 (not so clear).

But I think it might be a later Pontiac straight 8 unit. Does anyone know the year, the series, the power?


There is a wrong carburetor (Argentinian production) fitted that doesn't work well.

Does anyone know the correct carburetor for the engine I have in my car?

If the year 1933 would be true it had to be a Carter W1 single downdrought.

If the year 1933 would be true the chassis number would have been 770,001 upwards - and not E-041448.

Does anyone have an idea? There's nothing on the frame, not below the left front fender, nor a plate behind the right front wheel.

The only numbers I found are on both sides of the rear axle:

left 367235 L 11

right 367236 R 15

Every tip advice information would be helpful.

Thank you

and a happy new year!

hi martin, what a beautiful pontiac roadster you have there, my master parts catalog only goes as far back as 1937. the pontiac oakland club doesn't have a 1933 pontiac technical advisor, but there is a 1934 pontiac technical advisor, he is very well known and respected in the poci. his name is kurt kelsey, 14083 P ave. iowa falls, ia. 50126. his ph # is 641-648-9086, and his email address is kelsey@prairieinet.net sorry i couldn't be more help, i hope someday, you'll be able to show your roadster here in the states. please give us a drive report, this car looks like it would be so much fun to drive, years ago, i was allowed to drive a 1934 pontiac convertible with the straight eight and three speed standard transmission, a BIG different than driving a 1953 pontiac chieftain custom catalina with the straight eight and four speed hydra-matic transmission. charles coker, 1953 pontiac technical advisor.

Hello Charles and Jim, thank you very much for the immediate and helpful response. I'll try to contact Kurt in the next few days and I hope he can give me an advice. If someone else can - please do so. As soon as I can find a matching carburetor I'll let you know how the car behaves on the road.

Best regards Martin

Hello Kurt, what a great pleasure! Your words are the first indication that the production year of 1933 might be really true. Until now I wasn't sure if they had just taken a 1933 Pontiac radiator grille and built a total fake around it. That's how they started their work:


The frame is not of the later Pontiac K-Y style - but it is a Pontiac frame at all?

Best regards
