Driving down the road in my 53 3600 Chevy truck! Recently put a Tach in the truck! Tonight I was driving to take the truck to get the pinion seal replaced. At 50 miles an hour, the truck was pushing 2500 RPM’s. So can this truck sustain 50 miles an hour for long period of time? Or is that pushing my luck?

2500 at 50 mph is very possible. What are your gear ratio in back?

- If you have to stomp on your foot-pedal starter, either you, or your starter, or your engine, has a problem.
- The 216 and early 235 engine are not "splash oilers" - this is a splash oiler.

I don't get scared until 3,000 RPM.
2,500 RPM is right in the wheel house of the optimal power range for these inline six engines.

4.57:1.
Oh and by the way my truck has a 235 in it. Not a 216.

So you weren't worried until you installed a tach? That's kinda like having a thermometer; you're not cold until you look at it - then Brrrrrr!

I remember when they all used to be spooled up that high to go down the highway. Seems gasoline engine rpm has decreased a lot since the late eighties. If the engine is in good condition it should be ok.

There has been some discussion on this topic recently, and I too myself have been interested in learning what the "reasonable" engine speeds are for these trucks. I run my 261 (and previously a 216) at 50-55 and don't think twice. The engine does sound like it's winding up pretty good, but I know they are designed to handle these speeds given proper lubrication and cooling. My thought on this subject is these trucks were not designed for freeway speed, and I become much more concerned with safety than engine speed when speeds exceed 55mph in stock form.

1953 31xx truck with 4.11 rear end?

What is the rolling diameter of your tires?

1953 transmission (there was a 1:1 top gear in the original 3-speed or 4 speed)

With those data, we/you can calculate engine RPM at different speeds.

Then, we can offer opinions (and BS) on what we consider to be a safe engine speed.
