With the stock factory ring and pinion, and with your engine up to snuff, your car should be able to go at least 55 miles per hour. A lot of guys run their cars around 45 to 55 miles per hour. If you have the 3.50 ring and pinion in your car from Larry Jackson, then 60 to 65 miles per hour would be normal.

Check your timing. If your engine is running retarded power and maximum speed will be diminished

Thanks:-)

I had now 10 years work on the car.....now i can drive it
i was make last week the registration in switzerland...it was alot of work to get the registration....the control the car like a new car!!!!!!
What kind of oil do you use for the engine?
the timing of the engine is now 12 degrees ist that ok?

12 degrees is the factory setting. However, if you want to improve performance and power, install AC-C87 spark plugs and gap them at .040". Bump your timing to 18 degrees (that's when the 12 degree timing mark is just about ready to disappear out of the top of the timing hole (advanced side), and you will notice a big difference in the way the car performs.

Here is a link that will provide you some information also. It has a lot of good and interesting information with it. It is all about 1931 but some info can relate to the 1930. http://1931chevrolet.com/troubleshooting.htm#why

Great:-)

The car runs now well

Thanks

Cool!

can I increase the gap to .040" and advance six more degrees using c-86 plugs?..

Yep! We talked about this many times in the past on Chevy Chatter regarding the AC-C86 plugs, which are now discontinued. Also, the information on Billy Boy's 1931 web site covers the AC C-86 plugs and the increased timing as well.

thanks...

You bet!
