  • Shelby Intake SJFD 9425 F

    Dan

    I know you've done a lot of research into the evolution of these manifolds, yes? I was wondering if anything can be inferred about the generation of my manifold based on the lack of the extra stud bosses on the #7 runner? My understanding was that those bosses came later in the series to attach additional equipment but I'm not sure whether productions couldn't have been carried out on both versions. And, do you know who cast these series of manifolds? Some sources have said Spearco?

    Thanks - Jim

  • Shelby Intake SJFD 9425 F

    Hello all

    I was recently given a "Shelby" intake manifold with the casting number SJFD 9425 F on the rear runner. There are no manufacturer's markings underneath. In what timeframe was this manifold available? Who was the manufacturer? I took it to the media blaster guy befor taking any pictures, sorry!

    It has four individual throats from the carb surface, not two large ovals. I've seen both configurations but I'm not quite clear on the advantages/disadvantages of the different configurations. What kind of carb plate should I use for a Holley 4150 vacuum secondary type carb?


    Thanks - Jim

  • Camshaft sprocket spacing

    Thanks Fred. I agree that the C-spacer and thicker thrust plate, with the clutch-headed screws are missing and I have something like the later (after L7) pieces in its place. How critical is the cam sprocket line up with the crank sprocket? Seems like spacing stack up may not align perfectly.

  • Camshaft sprocket spacing

    I am replacing my timing chain, cam, and cam shaft sprocket on my 64 engine, built Nov 1964. The cam sprocket is currently a S-406T. The engine has the 0.250" thick cam thrust plate with the hex bolts. I've seen the warning sheet like the one I've attached here that indicate than an extra spacer might be needed - how do I know whether I need that? The engine, as assembled, did not have another spacer. Neither the old cam sprocket of the replacement sprocket I bought has an extra step on the rear boss like shown in the aarning sheet. The crank is the original Hi-Po with the pinned hatchet balancer. The crank sprocket has no markings that I can see. Do I need to worry about a spacer?

    OK, well, yes! I am ready, especially for numbers matching:exclamation: I had put an ad in lost and found. 5R09K157625.

    This HEH-T toploader was replaced by a shop in Southern California in 1999 with a T5 installation. The shop does not have any records (I have invoice from the work done for the PO). I would like to re-unite the VIN correct components!

    It was removed in Santa Ana in the late 1999. Shop changed hands and no oldsters are there any more.

    Thanks for that, Fred. I know 3.50 is a bit of a comprimise. I've had Mustangs with T5s with 3.08 and 3.45 gears before. But I hope someday to locate a proper CR toploader to put back in so I wanted to have the 3.50 to match the original build.

    I knew that my current ratio was probably 3.89 simply by seeing what RPM I was turning at 70 MPH in fourth (1:1). My 69 Boss 302 had 3.91 gears and I was very used to cruising at 4000 RPM in that. However, it was a 5 minute job to jack up the rear end, stick my phone under the car facing the driveshaft, spin the rear wheel ten times and watch the video to count driveshaft revolutions. Ezeey peezey ;)

    Welcome to the Kommunity. You have a great driver Kar there,

    What rear end gearing do you have?

    -Fred-

    Fred - I counted turns (it's an open diff) and determined that it's 3.89. That's way too low for the T5 since it has low first and second ratios. I am going to put a 3.50 back in it (original ratio according to the door tag) and see how that feels. Getting a few other things sorted but it's running pretty well!

    I brought home the 65 K-code 2+2 that had a lead on. I'm very happy with it, very straight and clean; a really nice driver. I verified the VIN on the engine block. The trans had been replaced with a Tremec T5. Other upgrades include a dual chamber master cylinder and power booster on the original K-H disk brakes, and power steering. There's also under-rider traction bars and Koni shocks. The distributor mechanical advance was frozen so I am soaking it in some penetrating oil right now. I found a friend to check the registry in V4 of the Tony Gregory HP Mustang book and it's not listed. My garage is full!
