In an effort to lighten up the forum, here's the first installment of Monday Memes....51 to go...

This could of been a picture of me about 1970 or so! I had a same year, same color fastback back then, was about that skinny, and same hair. The only way I know it's not me is I had Torq Thrust D's on mine.

Wow, I've managed to put 23,000 miles on my '67 in the 16 years that I have owned it. I'm only on my second tank of gas so far this year...

I'm in Coon Rapids, Minnesota, just a little north of Minneapolis. I think everyone knows where Minneapolis is right now... My wife Barb and I have been married for 51 years.

My 67 convert has so much wind noise, it's actually quieter with the top down. Seriously, it is.

I'm not upset at all, but I really don't have any interest in the newer Mustangs. The 65 through 69's are great and I can kinda tolerate some of the Fox bodies, but that's it. And then a car starting at 44K is a little out of my budget anyway.

Ya know, every time I read through one of these electric fan threads, I'm reminded of all the trouble I went through with mine. I tried 3 or 4 different set ups, and the ones that worked were too loud and ugly, and the neat installation just wouldn't cool enough. Since going to the fixed blade with fan clutch, custom fitted shroud, 30% higher flow waterpump I have had zero issues with engine temperature. I get caught in traffic in over 90 degree heat, even sitting and idiling for long periods and the temp guage stays right at 190 degrees. Although I do kinda regret removing the A/C that the car originally came with. 

No, no spring in lower hose. All hoses were new 10 or 12 years ago, and are still very sturdy feeling. I don't think that high volume pump really flows that much more. The impeller is a tad bigger but it's only supposed to flow 30% better. I will keep an eye on it though. 

I ran a 650 cfm Holley on my mostly stock 67 289 for about 10 years. I was never really happy with it as it tended to run rich, especially when first started. After warming up it did run pretty strong, but gas mileage was all over the place: worst was 11.5 mpg and best was 16. Idle was inconsistant also. Last fall I put a 500 cfm Edelbrock on, spent maybe 20 minutes tuning the idle circuits and just started to finally enjoy driving it. It cold starts with one hit of the gas pedal, fast idles at 1100 rpm, and kicks down to a smooth 650 rpm idle every time. No more eye burning exhaust when warming up, and my milage this summer after driving 2200 miles in all kinds of conditions has stayed between 15.8 and 17.2 mpg. I am really happy with this set up, I wish I would have done it years ago!

Having gone through a bunch of overheating problems in the last few years with my relatively stock 67 289, I feel qualified to offer my opinion. My setup has evolved into this: a 20" wide, Champion 2 row aluminum radiator with a slightly modified OEM type shroud, 17" 6 blade, fixed blade fan, thermal clutch that is supposed to run at 35% when cool and 85% when underhood temp is over 175 degrees, an alumimun high flow waterpump from Jeggs, supposed to flow 30% more at idle, and a OEM Motorcraft 192 degree thermostat. Since putting all this in place I have had zero issues with overheating. The engine warms up to an indicated 190 degrees and stays there no mater what. I've been caught in horrible traffic in 95 degree weather for over an hour at a time with no increase at all in temp. I've also noticed my oil pressure at 650 rpm idle stays right at 25 lbs now wher it used to dip a bit below that when it was running less consistantly. The oil stays noticably cleaner now and my gas milage has been staying right at 16 mpg all summer. That's about 2 mpg better than it was. The coolest weather I've driven in was maybe 45 degrees, and the guage stayed the same 190 degrees. I've also noticed there seems to be way less heat soak than there was before. Not sure if it's from the better circulation from the waterpump, or better airflow from the fixed blade fan, because that fan does move a lot of air, way more than it ever did with flex fans and/or electric fans. Very pleased with the way it worked this summer!

I'm with MS on this. I fiddled around with aux pusher fans, shrouded puller fans and even both at same time. I was unhappy with the looks of the setup, and also the noise when running. My last change has turned out to be really good and I'm convinced I've solved the issue. I'm running a 2 row aluminum radiator with the 1 inch oval tubes. A stock OEM fan for A/C with a thermal fan clutch and a slightly modified stock shroud, (to fit the aluminum radiator) along with a 30% higher flow rate waterpump and a 190 degree Motorcraft thermostat. I don't have air, IT"S A CONVERTIBLE after all, but I have tested this setup a number of times in our local summer traffic jams in 95 degree plus temps for almost an hour at a time. Even stuck sitting at idle the temp stays right at 190 degrees. My idle is set at 650 rpm and that clutched fan really moves the air through the radiator. I've also noticed since running very consistant temp that my oil stays really clean and my oil pressure at idle is very even 28 psi. It used to drop below 20 when engine was running hotter and more inconsistanty. Kinda wish I'd done it this way 12 years ago when I first started having overheating problems. Oh well, better late than never...... 

I've posted before some of the issues I've had with the cooling system on my 67. Last summer I thought I had it all figured out with a high flow waterpump, OEM a/c fan with clutch, modified fan shroud to fit my aluminun radiator and 180 degree thermostat. Worked very well all summer for keeping the engine running cool, but I did notice the temp was actually falling with higher speeds. Late last fall we went to a weekend long car show up in Crosslake, MN, and as luck would have it it rained like crazy on the trip home. It was also pretty cold out. Well the engine never got above about 130 degrees all the way back, about 190 miles. I figured the thermostat must be faulty, so this spring I decided to replace it with a 192 degree OEM thermostat. I'm a firm believer that engines run best at those recommended temps. So yesterday I drain the radiator and pull off the thermostat housing, and what do I find? I had installed the thermostat backwards! I still can't believe it. I've replaced probably 20 or 30 thermostats in my lifetime and I hope this is the first (and only) time I've done it wrong. I put the 192 in correctly and after 2 test drives I think I've finally got it. It runs right at 192 no matter what speed I'm driving. I'm guessing my main problem before was poor flow from the original waterpump, but I can't be sure cuz I changed too many things at the same time. Oh well, it's fixed now and I don't need those ugly electric fans any more. 

I was a "fan" of the electric fan setup for a few years, but recently changed my mind. I was tired of the look of the flex fan, no shroud, electric pusher fan set up that still would run hotter than I wanted in slow traffic. I switched to a aluminum shroud with 16 inch puller fan. Unfortunately the motor on the 16 inch fan interfered with the waterpump pulley. I bought a replacement motor with the highest amperage I could find that was thin enough to fit. Would not flow enough air when really needed. Decided to go old school and changed everything. Went to a high flow aluminum waterpump from Jeggs, a high flow 180 degree thermostat, a 17 inch, 6 blade a/c fan with thermo clutch, and a stock type shroud that I had to slightly modify to fit my Champion radiator. I realize changing 4 things at once is not the best trouble shooting method, but I am more than happy with the results. I've tested by getting stuck in stop and go traffic in 95 degree heat for over an hour at a time. Runs between 175 to 185 degrees no matter what. It's all about the air flow!
