Bought A 69 Mach 1 The Other Looking For Some Thoughts On Mods??

  1. Hi, Haven't posted on Stangnet for some time as I haven't had a Mustang for a couple of years. However, I recently got the itch and was cross shopping classic fast backs with 2012/13 Bosses. Two pretty different cars I know, and in the end I ended up buying a completely restored 69 Mach 1! I went with a Mach because I intended to keep whatever Mustang I bought for a good period of time, and well a Classic is always a Classic, and a new Boss becomes old news after a year or two.

    I've had the car for a couple of weeks and it's crazy how much attention the classics grab, but I'm also a go fast enthusiast.

    The 351W drivetrain is freshly re-built with the following gear:

    Original 351W bored .030 over, not exactly sure on compression
    Edelbrock RPM heads # 60229
    Edelbrock camshaft # 2182
    Ford racing valve covers # M-6582-E302P
    Roller Cam Crane Cams rocker Arms 3 11746
    (1.6 ratio w/ 3/8 studs)
    Crane cam components #44621-16
    AOD automatic with Shift kit# B&M 40263
    Edelbrook carb 1406 600cfm
    MSD Distributer Part # 8354
    Rad Fan 16”, S blade Maradyne #M162K
    Magna Flow 2.5 “ exhaust System # 15816
    Long tube headers
    3.73's rear gear ratio

    The car as it sits isn't exactly slow, but it's not fast either. I posted this build up on some other forums and got and estimated HP of about 350-400Hp. But it just doesn't seem like that much HP is on tap, so I'm talking it to a shop for a tune up to see if some easy HP can be had with some jetting.

    I'm also not sold on the shift kit in the car so I might have them install a TransGo kit any thoughts on these? As the AOD is currently lacklustre on the 2/3 shift and holding second for any length of time, but it does bark the tires into second on the 1/2 up shift.

    What would be some reasonable thing to do to make this combo allot hotter? I was thinking an Air gap intake, bigger Cam and keeping the RPM heads for now??? Because the engine is freshly re-built, I don't want start tearing completely into just yet, and crate motor could be in the cards down road so I don't want to sink too much money into it either. Any suggestions are appreciated.

  2. Yeah ,we need some pics, Congrats on the new 69.
    Just my opinion ,Keep the 351 its one tough motor .
  3. Your engine combo is just like mine, except I got the Edelbrock Air-Gap and a BG Speed Demon 750VE (Have swapped it for an Pro Form 750 - but not driven it). I also got a cast Scat crank, forged Scat H-beams, and Wiseco Pro-Tru forged Pistons, 10.80 Comp ratio. Also got a 3.70 Tru-Trac diff. One thing I'm sure of, you're under-carbed. Put an Holley 650 or 750 on it. The Air-Gap is an no-brainer.
