Hello!!
I have owned my 1970 Panel Bus for 6 years and finally just recently installed a Porsche 912 Tachometer. I was amazed at the RPM I had been driving my Bus at. My speedometer doesnt work right and I haven't changed the cable, but it would be off anyways I figure because my bus is wearing some big boots. Anyways I have a stock 1600 single port engine with a slightly bigger cam. The RPM's I have run before installing the Tach were ~3600 RPM's at top cruising speed! Now I've slowed down to between 3000 and 3200 RPM's. I don't know if the previous RPM's were too high, but it seems like my gas-mileage has improved a bit. So I would like to know if the RPM's I'm running now are safe for a longer lasting engine, as well as if my previous RPM's were way too high.
Thanks for your insight, I've enjoyed reading posts here for several weeks and finally created an account. Happy Trails to you all! (:#
