Thanks for the replies. The old girl was original with 82k on the clock . After about 3k of touring she blew. Everything but the steering components (next job) are new. I just don't have a clue what she's spinning at 50 mph.

Hello, I have a stock 50 coronet with a gyromatic tranny. I have no tach. What is a safe road speed and what rpm would that be?

Any opinions on running non eth in a flathead?

No. I got lucky.Funny thing was, when I took the head off the broken valves were in the seats.

Drove home like this. Unbelievable!!

I cleaned the points and checked the oil level ,it was overfilled because I only lifted one front side to have access. Shifts as it should now. I need to reset the magnetic dashpot to prevent stalling on abrupt stops. Thanks for the advice. Anyone with a gyromatic should watch the chrysler master tech video, it is far better than the manual.

Thank you all. I appreciate all of response. I have driven in the high range and come to a stop without the clutch, the acceleration is poor to say the least with no upshift. After reading all response , could it be the dashpot adjustment ? I know the ignition cuts off to allow the upshift but like mentioned shifting is perfect in low. We have a steep hill with a stop sign above our garage.

50 Dodge Coronet Gyromatic shifts up and down as it should in low range from first to second and back without use of the clutch, but in high range seems to be stuck in 4th gear. I have drained and refilled the oil (10w) three times and engine rpm is 450 at idle. I have a manual, and vintage chrysler service videos . I rebuilt the motor and carb , wiring, cooling system. Any help appreciated before I pull the tranny.

Ply Adam's, could you direct me to a reliable source for new parts?

I'm a crusty old anal machinist and was hoping to get an an actual dimension from someone.

The old exhaust guides shattered. My new parts came from Andy Bernbaum. I c' bored them .500 deep x .375 to clear .020 over valve stems. Then reamed the guides to .343.

Hello, my new exhaust valve guides were not counterbored. Anyone know the dimensions ?

Anyone know where to get a dashpot solenoid for a Stromberg bxves-3 carb?

Don, I'm not as polite as cold blue, so I'll just keep reading my new 600 page shop manual.
