    Cometized ---Thks for shedding some light on where I saw the post on this topic. It had not been that long since I read it; I had seen/read it B4 this recent reading. I replaced my engine fan, with elec for the safety reasons along w/better cooling. Not just frm explosion standpoint, but from a possibility of getting a body part caught in it and loosing a limb - or worse. All it takes is a split second "loss of concentration" and ur in route to the hospital - or worse.

    Even the electric ones are not perfectly safe. I cut off my thumbprint on mine once. Engine was off but it was still spinning and I just barely touched it and filleted my finger.

    Well then I'd better look into getting a higher amp alternator.. And find a suitable circuit to run the fan off of. I'll probably make my own shroud out of 20 gauge steel when I get the chance though for now. I haven't even hit my 20's so is definitely like to not be killed by my own creation.. That's terrible just hearing about it. In the mean time I'll try and find a replacement radiator. I think summit has one for around $250 which would hopefully solve my cooling problems. I love driving the car but I hate having to watch the temp gauge like a hawk every 20 seconds. It gets rather demanding at times. It even overheat if I drive too long/fast on the freeway. So it's definitely a nieusance.

    No doubt! I had to do the same thing. It would slowly creep up to 200...210...220. Then I would have to pull over for 20 minutes to let it cool back down. Made a 60 mile trip take almost 2 hours.

    A little bit off topic, but perhaps related, is my vacuum readings at idle. (keep in mind its a relatively mild street cam so it has a little bit less vacuum I believe) When plugging a vacuum gauge into the manifold vacuum port in the carburetor it shows a steady (slightly shaky) needle. It kind of sits there and vibrates really really fast between about 16 to 16.5. I mean the shaking is not really too noticeable but enough for me to question it.

    I now have the vacuum advance hooked to manifold vacuum source. It used to be plugged into ported vacuum (and the car ran at a steady 190 usually everywhere when I had it there strangely enough.) but I messed around with the timing a little. I never though to watch the vacuum gauge while playing with the timing though... -_-

    Could my overheating partially be attributed to late ignition timing as well? I can always play with the vacuum advance canister a little. I think total advance is set about right so I think I can adjust the curb idle with an allan wrench correct?

    Overheating can happen from too far advanced timing. Not if it is retarded/late.
