Safe cruising RPM for 304 V8?

Oct 30, 2003 1 Replies

Just curious. I drive my Jeep to work and do 65-70 mph on the way in.



31" tires, not sure of the gearing in the differentials yet (gonna look this weekend), 3 speed, 304. I'm really only guessing at my speed right now because the speedo acts crazy...like it works at first but then it sort of "slows down"...but not always. Just bizarre. I have a problem with the connection at the xfer case end that I haven't gotten around to fixing yet. Anyway, assuming my tach is working correctly, what would you guys consider to be a "safe" crusing RPM for my 304? 2000 RPM? 2500 RPM? 3000 RPM? I appear to be (if I can trust the aftermarket gauge) running around 190 degrees but have seen it climb to as high as 205 on the 3 1/2 hour trip home the day I bought it. Thanks for your input.
