  1. I wrote that info down somewhere when I first purchased the car but I cant seem to find my notebook at the moment. But if I remember correctly, the date code was "0F23". I don't know the casting number yet. I was going to obtain that info when I replaced the cam. The heads have the "4" marked on them without the dot on them. There is so much disagreement on what the dot means though. Some say it means open chamber while others say it means nothing at all, while even others say it appears on heads manufactured after a certain date.
  2. My 73 Mach-1 has a 1970 M-Code (Toploader 4-speed) with the 4V closed chamber heads (11.0 compression according to Ford spec's). Initially, I was thinking I wanted a street and strip car but recently I'm thinking I would be very happy with a good high performance street machine. At present, all is stock except for an Edelbrock Performer intake, Holley 4160 (750 cfm) carb, MSD distributor and ignition, and turbo mufflers. I too have 3.25:1 rear gears but no traction-lock (yet). I really want a good performance street cam with a very noticeable lope at idle (I love that sound) but I have power steering so I still need a decent vacuum. Headers will be added soon and I'll be going from 225/60R14's to 295/50R15's in the springtime so I may need a slightly lower rear axle ratio to spin those puppies.
  3. That is one of the ones I looked at (found on Summit racing's website). I was hoping for ceramic coated but the #6915's in ceramic are twice the cost of the painted black tubes so I'll take what I can get that fits. It says that they will fit the 4V heads and with a manual transmission and power steering. They might be the ticket. I don't plan on driving it in rain or snow and its garage kept so the plain steel ones would probably last a long time. Maybe if we get that 2nd Stimulus check, I can splurge.
  4. Using the spread sheet provided earlier, it tells me to use a cam with 290 degree duration and 110-112 degree LSA.
  5. Does it matter that my 351C-4V motor is an early 1970 M-Code (11.0 compression). Would it still be too much cam? Richard Holdener who seems to be quite an expert on small blocks (Chevys, Mopars, Fords, and his favorite is the Ford 351C) has a bunch of YouTube videos where he installed this cam in a pretty much stock 351C-4V M-Code with the same compression and closed chamber 4V (quenching) heads and produced 450 HP and 491 Lbs/Ft. of torque. Although those numbers were achieved well above the 5200 RPM mark.

  7. I thank you all for the welcome.
  8. Does anyone have any experience using a "Comp" Cams XE284H camshaft in a 351C-4V (M-Code). I have been researching cams for awhile and am looking for a good performance cam for street and occasional strip use in my 1973 Mach-1 and so far I am leaning toward the XE284H. I don't mind a moderate lope at idle and actually like that sound in a street machine. I was wndering if anyone has any pros and cons on using this particular cam. My car has a 4-speed Toploader and 9" rearend with 3.25 gears and I will be adding headers soon but currently have a Edelbrock Performer manifold with a Holley 4160 (750 cfm) carb and an MSD 83501 Distributor.
  9. Thank you for the welcome.
  10. Yes, I do have power steering on my Mach-1. According to the Hooker website and Summit Racing's website these will fit but I was hoping someone out there could confirm that before I purchase them. Nice stang by the way. That's pretty sharp! I need to reupholster my interior also. Both front seats are torn and my drivers side armrest is badly damaged.
  11. I'm a new member to this forum, having just purchased my first big nose Mustang a few months ago from a gentleman in Fredericksburg, Virginia. Its a 73 Mach-1 Sportsroof, 351C-4V, 4-speed in Blue Glow paint. According to the Marti Report that I purchased it was originally a Q-Code but the previous owner had replaced the motor with a 1970 351-C-4V M-Code many years ago. So there's no chance of ever having it be a numbers matching car. But that M-Code motor has the high (11.0 to 1) compression, closed combustion "quench" chamber 4V heads so it does run well and for that I am very pleased. The previous owner installed an Edelbrock Performer aluminum intake manifold along with a Holley 4160 (750 cfm) carburetor. It has the stock exhaust manifolds and turbo mufflers and it sounds quite good. there is absolutety no rust on the car anywhere but the drivers side floor pan was replaced at some point. The paint is still in good condition, having been repainted at some point in its life but it does have its share of minor nicks and scratches so I plan on having it repainted over the upcoming winter. So far I have installed a new clutch, pressure plate, and 164 tooth flywheel along with a new power steering pump, several brake lines that looked questionable, and all of the rear taillight sockets. I am now planning installing a better performing cam like the Comp XE284H which I've read good things about and Hooker Long Tube Super Comp headers. If anyone has any recommendations, experience, or suggestions on this cam and header combination, I would greatly appreciate the input as I'm not sure if the headers will fit properly. I also want to replace the stock 14" Magum wheels and 225/60R14 tires with 15" rims and larger (295 rear/245 front) tires by next spring. I'm glad to be a member and hopefully I'll be able to contribute to the forum.
