The first thing you have to consider when dealing with {Name Deleted} is that he forms essentially instant opinions and never ever, ever changes from this position. You can through all the logical analysis and facts you want, it won't change his opinion.

Actually my e-mail address is something Rob thought up when we were just getting into the internet and e-mail. It's "modtiger" after my tenacity to change everything on my Tigers. The engravers.com is my web site address for my company Sine-Tific Engravers. I did not think of this unusual trigonometry based spelling, but it's tricky enough for many technical people to remember, so I've kept it even though my business does a lot more than engraving. We do have a full Screen printing department and have made decals on both water slide and mylar based materials. The web site lists more of our actual capabilities, but I haven't found it to be much help in the sales area. The domain name became available and I figured it was better to have some kind of a presence on the internet than to ignore a potential growing marketing tool. Feel free to check it out and let me know more precisely what you are looking for. BTW we can create most line art graphics in house.

No, the valence is stock minus the oil cooler mounts. The radiator bulkhead is another story. Prior to 81, when I bought Blue, It had a rough life starting back east. Much of the bulkhead was cut out. If you examine the bulkhead, you will see a lot of air flow restrictions over the core. I typically remove the entire bottom of this assembly, including the center brace. This really opens things up. My fan is mounted on an aluminum frame just in front of the radiator with a rubber lip to provide a seal to the core. It is only about 5/8" from the core tank header on either side. Can't get much bigger. My fan has straight blades with more noise as opposed to those curvey fans that run quieter but don't move as much air.

I checked a lot of this out with thermocouples when I was an engineer at GE. That was another life and I don't have any data that I can put my hands on. I also don't have those kinds of resources at my disposal. I keep promising myself that I need to but some of this kind of instrumentation, but since I haven't had many problems in this area recently, it gets put off. I feel bad that I don't have the time to setup proper instrumentation and prove some of our theories to the skeptics, but running my business with 10+ employees and building Rob's 351W with major suspension and structural changes keeps me very busy.

I trust in Earl's hardware for my plumbing needs. In Blues earlier days as a "runner", I blew a hose to the remote filter on the freeway. This was one of those "push-on" sets that was on the car when I bought it. It was running a essentially stock 289 and when I saw the gage at 0 and got out of the fast lane onto the shoulder, the pan was empty. I figured it had wiped out the bearings, but there was no major damage. I changed the hose, filled it with oil and drove it another year or two before I pulled it down for its 10 year rest and restoration.

John,
I second (or third) Bob's and Jim's suggetion, with one step further. If doing a recore, it is critical to dictate to the shop the core you want. I have had good luck with the following: MODINE 4 row core, "H" model that is 2-1/8" thick, with a fin spacing of 14 fins per inch. My original appeared to be rather stock and 2-3/4" thick. This hi-po retrofit worked quite well for me, and looks very stock once the copper core is painted black.
Regards,
Allan B9472373
