Engine speed?

[red94]

Now that I have a vfresh valve job and new head gaskets on my 94 3.0 engine, I'm curious .... how fast can I safely run this engine?

I only had this truck about four months before needing the engine work. It has about 100,000 miles; rest of engine (compression, etc.) checked ok and it's a nice clean rig.

I'm running in the Colorado mountains, about 7000 to 11000 feet elevation.

I need to keep this thing wound up a bit to hold speed on the highway, but what's the max rpm I should run for any length of time? (It's a 5-speed manual trans).

I don't want to hold up traffic, but I don't want to cause any engine damage. This valve job/head gasket deal was $$$ enough.

Thanks for your help.

In the owners manual toyota gives you the shift speed if you get up to several of the shift speeds its normal about 3000 rpm. so any thing below about 3200 you could run safely i would assume

It's totally impossible to maintain highway speed on a hill (any hill) with the 3.slow keeping the rpms at/below 3200 rpms at Colorado altitudes.

Daemon understands the situation.

So how fast can I run this engine without any risk of damage?
Or do I simply chill and get in line with the semis?

Chill and get in line your fine unless your beating on it (redline it all the time) going through the gears. you know what I mean.

I run mine at 80-85 MPH on the highway and got 140K on it.
