84 K5 RPM

Sep 25, 2003 13 Replies

What is the "redline" for an 84 Jimmy with the 5.0 (305)? Just put in a tach and guessed 5K for the limit. No Shift light to worry about, just curious. Somehow I don't think it's imperative as I doubt I'll bring her up to the "limit", just want it to "look" right.



TIA John



I've seen 2 limits on the 305, 4500 and 5000, with 4500 being the most common. That's a guess, if no one's got anything better.

Thanks John. I was just out there tinkering and it's actually sitting at

4500. Figure it's about normal and If I'm hitting that high of RPM, then I had best take stock of the bank account and the nearest gas station location....LOL

The way I did that on my S10 is to put it in 3rd gear when I was doing 70MPH and found the engine governed out at 5,500RPM. I'd probably try something like that. I have the crappiest little tach you'll ever see, but I wanted the red light to mean something.

Wow, that's brilliant. You don't go by the name Checkmate every now and then, do you?

Care to be 'splaining the governor operation on an 84?

No, it isn't brilliant but he wants it to mean something. Not like one tach out is going to kill it. Besides, it would be fun to watch this beeterbox burn.

So where might one find the governor on a carbed 305? Just curious... And after my beater box burns, feel free to swing by so I can return the favour. One good turn deserves another...

Where's the governor on a carberated 305? Simple....Under the valve covers ;)

That explains it then I guess LMAO

That's the 350. On the 305, they moved it to the back of the motor, near the muffler bearing.

------------------------------------------ Nope, Its under the valve covers on the 305 also. (I meant valves floating) :)

Oh OK, So I guess I can put away the headlight fluid.... That's a relief

Sorry, but I'm not commanding you to hold your foot to the floor in idle untill your engine self combusts. Infact, I'm not making you do anything. However, I am telling you what my little red needle means, and that I now know how hard I can push it if I need it. But also, why would an S10 have a

305? It's a 2.5 straight four.
