Question
I have a 1956 Chevrolet 210 with 6 cylinder and powerglide transmission. Runs great until 50 then seems to hesitate or miss a few beats. Original 50000 mile gar.

Answer
Hi Again Pat:
This could be a number of things, but since you say the problem only occurs at speed 50 mph or higher, My first guess would be a faulty fuel pump.

This could also mean a foul plug or clog fuel filter. You may have to drive her a few times under different conditions to help me nail down the actual problem. If this is a fuel pump problem, it won't improve. But if it is a foul plug, it may improve a bit with more frequent driving. Driver her some more and get back to me.

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
