    Do note that the commonly available, that is something other than what the U.S. Military or N.A.S.A. might have, "I.R. Temperature Guns" are often prone to interpreting the values being sought improperly; as this is a referred value that can be influenced by, among other things, the specific items' emissivity, surface material, including color & finish texture, and then there's also interference from the environmental factors.  :o

    Also realize, that even "if" accurate, this value is only as of the actual surface, aka not the "core temperature".  So for example, if "shooting" the radiator core (tube & fins), that which is being presented is the "surface temperature", not the actual water temperature within; and as with something like this, the difference "should" be significant!    ;)

    An instance of how the populous is just determined to "shoot themselves in the foot" on this topic of "Walmart-Mentality", this that was brought forth in our shop one day; as a guy had purchased a couple of the 'cheap' "Garrett Like" turbos off ebay, and on the first hard-run, both the compressor and turbine blades shredded, and of course this lead to internal engine damage.  After incurring a somewhat rather extensive repair requirement, this at a rather great expenditure, on his way out the door with his "fixed stuff",  I inquired as to what he was going to do for replacement turbos this time around?   ??? 

    His response was that he was just going to order another pair of the same "CHEAP" turbos, those that had blown-up on him previously!   :o   I said:  "What the F@#K!  Didn't you learn anything from the previous experience?"  He said: "But they're just sooo . . .  cheap!  I can buy three sets of those for the price of only one set of the "GOOD ONE'S".    ::)

Quote from: JohnSlack on December 24, 2025, 07:05:33 PMRewarding groups that make inferior junk that you know is inferior junk instead of buying quality parts is why people stop making quality parts.
 
Crower made excellent billet connecting rods, Childs and Albert made excellent connecting rods. The Chinese have expanded their own manufacturing capacity and abilities based on cheap inferior copies of other manufacturers around the world. Shame on anyone who buys something predicting that it may need to be completely reworked or sent back, when it is sold as a finished product.

     HALLELUJAH!   ;D

     For crying out loud, when are we going to LEARN!   :-[

1967 Shelby GT350/500 / Re: GT-500 intake questions
December 22, 2025, 04:14:03 PM
    Yes, definitely "modified"; that from as it was produced by the O.E.M..  ;)

    This was/is a popular modification, which is most efficiently accomplished with a "plunge-cut" from an end-mill and then "deburred" to remove the sharp edges, this to increase the effective area of the "plenum" and thereby in an attempt to extend upward the R.P.M. functional range than would be otherwise.  :)

SAAC Forum Discussion Area / Re: 289 head with E casting?
December 16, 2025, 11:20:38 AM
Quote from: TA Coupe on December 16, 2025, 08:07:01 AMI think it's an experimental head.
 

    Well, at least the "E" as of inquired upon wasn't intended as an identifier for "Experimental" as I have more sets of these so marked heads sitting on the shelf here.  ;)

    Now, as for the intent in the plumping, though it would seem that it ties the two intake runners together, so . . . . . maybe a poorly executed plan for runner balancing/dampening with a Weber intake?  The springs and retainers are not O.E.M., maybe the rocker studs are also something different, so maybe was a "racin' thing"; or maybe even somebodies' '70's idea for better gas mileage?   ::)
 
    But in the end, for what, I don't know?   :-\
   
    But whatever, when you done starin' at 'em, if you strip the casting bare, then they make for 'great' wheel-chocks; or, if the "wifie" continually bounces the nose of the car off the back-side of the garage, then bolted down to the floor, these also make for 'great' parking stops!   ::)

Quote from: lwg8tr0514 on December 08, 2025, 09:55:08 AMOh and I am suprised no one has said .... this whole topic is a sales pitch for Edelbrock carbs  ;)

    Please no! This is almost the same (and as bad) as the incessant "LS-Swap" advisories!  :o

    But, I will admit that there 'is' an Edelbrock on my '60 T-Bird (installed by the previous owner), but I've still got an out on that one, the "J"-codes came with Carter's originally.   ;D 

    As for the reason Holley's have won-out on the "muscle cars" and with racers isn't just because they 'are' easier to work with, but also because one for one they will "generally" always out horse-power the others!   ;)

Quote from: lwg8tr0514 on December 07, 2025, 03:20:20 PMSolid advice here gents.  :)

    DO NOT use "RTV" (or "most" any other of the "sealers" readily available at the auto-parts or hardware store) as these will most often prove soluble (in time) to fuel.  ;)

Appeals / Re: Pressure plate rebuild.
November 25, 2025, 12:33:07 PM
    The idea of rebuilding the old pressure plate is a more than reasonable avenue to follow; that is, if you can find a "reasonable' rebuilder, and if not, might be willing to assert one's self into the endeavor; this as I attempted to present in my previous post, it really isn't that complicated.

    The only real pitfall might be any needed "parts".  As long as you don't have to find replacement parts, just a reworking of the old stuff and you'll be O.K..  In the "old-days", parts weren't a problem, I even still have the old catalogs from that industry listing all of the different applications and parts & pieces, and as often practiced in the automotive community, much being shared from one to another in the effort to reduce the "cost per unit" scenario, and note that clutches have always pretty much been a "buy-out product" for the automobile manufacturers; but today, I just don't know where to buy the O.E.M. replacement pieces?

    On the subject of a replacement clutch being of the "diaphragm" type vs. the original "long-style" in these cars has been discussed previously on this forum, and I would suggest that before anyone followed down that path that they familiarize themselves with the expected experience.

    Note that commenting is often intended as not only in aid to the O.P.'s inquire at this point in time, but also to provide to others whom may be "in the same boat" so to speak, this both today, and even perhaps, should any of this be available for review in future.  :)

Appeals / Re: Pressure plate rebuild.
November 24, 2025, 07:26:58 PM
      Most all of the "clutch rebuilders" are gone; but it isn't that difficult if you just have a "good" machine shop available.

      Assuming that you do have a "Long-Style" clutch, and it's not in a really bad state of condition, basically, for a "standard" rebuild as most often having been practiced by the shops in the past:

      Disassemble the unit via the three bolts located on the hat inline with the fork-fingers, loosening slowly and equally, the spring pressures "might" be released before you run out of threads, BUT! I prefer (and probably wiser & safer!  ;) ) to utilize the hydraulic press (but could be accomplished with a couple of pieces of metal and a long threaded bolt or a section of all-thread acting as a clamp) and hold the hat down until all of the bolts are out and then release the hydraulic pressure (or start unscrewing your contraption) this allowing the springs to push the hat apart from the friction plate.

      Now just gather-up the parts; inspect the pieces and note any shims that might be under the fork-finger stands and the positioning of everything (there's not that much there!  ::) ), including indexing.  Take the pressure plate friction ring to a ("general/industrial") machine shop that might have a magnetic plate for mounting on a surface grinder (and with "rotary table would be even better!) and have them dial-indicate the face level and cut a minimum off to "dress' the surface.  Sometimes (and actually best  ;) ) an "automotive type" machine shop may have the ability to mount this in their "flywheel grinder" and will also generally be more affordable in costing.  But if you find your having to walk them through the process then your probably at the wrong place! 

      Take the springs to an automotive machine shop and have them run each of them across their valve-spring tester, this looking for any that might really be bad; if any show to be significantly "out of range" compared to the others, then you have a problem, as not "any" spring will do and all should be replaced as a set.  And then see if they might happen to have some valve spring shims (say... .060") that will fit under the spring and within any machined recess or boss that there might be on the back-side of the pressure plate ring, this to offset loss pressure due to fatigue, for the removed sum on the face of the ring, and just to "add-in" some for good measure.

      The fork-fingers might have some excessive wear on the tips, that might need to be "dressed", this where they come into contact with the release-bearing, if not too excessive, and with some technique, just grind them down "some', in a radius fashion, but 'do' try and make them somewhat equal. 

      Now, as stated in the manual, "assemble in the reverse of the disassembly process."  ::)  When done do look and establish that the three fork-fingers are "somewhat" equal in height, as bolted to the flywheel with the friction disc in place.   ;D

      If you find that the hat is cracked somewhere, or any "broken stuff" or stuff that just looks overly "worn out", then it's just time to toss-it!  :'(

Quote from: Bob Gaines on November 23, 2025, 08:42:07 PMWith that in mind I typically suggest to port out the C0AE casting to look similar to the C8AE version inside passages. It doesn't take too long to do.

      Yes, one 'can' improve upon the "COAE" port flow, some, . . . . but it doesn't possess the material to make it equal to the later version.    :)

      And do keep in mind, that apparently F.M.C. had determined that the design needed changing.  ;)

      Scott.

      Agreed that it isn't going to be "correct", but if one were intending to "run the car hard", at all, I'd recommend going with the "updated" engineering of the "C8" product, which is more efficient at passing the oil volume, vs. the "CO" item.  :)

Quote from: Bob Gaines on November 17, 2025, 09:22:29 PM65/66 Mustang with factory 9 inch rear end used 28 spine axles.

    Yes I do understand that.  ;)

    Rather, I was simply attempting to make reference to qualify what someone might consider "nothing outrageous"; and I chose the 31-spline axle as a possible analogy threshold for the reasonable application of the 8-inch axle unit, not an argument of actual fitment.   :)

    Some of the initial product examples from B.T. did have the "FoMoCo" as cast, but Ford Motor Co. was quick to point out to him that that was a "No-No"; so he removed this for later production examples. :(

    Then it seems he did make an agreement with F.M.C., as they then had started to chase him over the "COBRA" logo also, and it seems intermittently cast again "some" (mostly the 289 "Cobra") with the logos, but charged an additional fee to cover the royalty he said he had to pay Ford for doing so. :)

    So, when it comes to the intakes that B.T. may have made, with some of them (especially after use and then having been abrasive blast cleaned) and for some individuals not so familiar, may have to basically be holding them in your hand to determine for sure. :-\

Quote from: SFcarbuff on November 16, 2025, 08:17:02 PMHe running a modified 289, nothing outrageous.

    Yes, and to be honest, a "nothing outrageous" 289, would probably do just fine with an "8-inch"; this as many have.  ;)

    But, if you feel that the project "needs" 31-spline axles, then a "9-inch" it shall be.  :)

Wanted to Buy / Re: 1966 1967 9 inch fill plug
November 17, 2025, 06:42:24 PM
    The threads in the back cover-plate are somewhat recessed as the hole is punched and the threads utilize the rolled material provided in the circumference bellow the 90 degree turn ; and therefore the beveled edge provides the service of aligning the greater diameter gasket needed in order to move the sealing surface out onto the flatter surface of the cover away from that radius. But the gasket thickness may be a concern so as that the bevel on the nut doesn't stop against the radius before compressing the gasket; where in the latter example such wouldn't be the case.   :)

    And although I do understand the possible intended purpose in the bevel as presented on the first as inquired of plug, that doesn't mean I'm attempting to state that it is "correct"; but somehow, as unique is that plug is, and that it does seem interesting "close", I'm thinking chances are that it 'is' a "rear differential housing fill-plug". just not sure if it the "right" one.   :-\

    But then with an appropriate gasket (copper would be a good choice) there's the old adage: "if the shoe fits . . . . . . ."   ::)
