    73 9 inch rear end seal replacement

    My mustang has pretty much sat in the garage ever since I bought it about 3 years ago waiting for a transmission swap. I would run it for 15 min twice a week. One day I noticed a small puddle of rear end oil. Now, with all the time spent at home I decided I'd give it a shot at replacing the...

    Transmission advice

    I am in a bit of a dilemma and wanted to get your suggestions. The FMX on my 73 with a 351C was suffering from “morning sickness”, but the last time I took it for a drive around the block it was slipping and I even thought I might not make it back home. In the end I did make it home but have...

    351C intake swap carb issues

    I recently swapped my stock 2 bbl intake and carb for a Weiand X-cellerator I bought used and a new Edelbrock 650 cfm Thunder series carb. My car is a stock 73 351C 2v with a duraspark ignition (bought it like that from the PO) and an FMX. I am having a couple of issues after completing the...

    My first car with FMX

    This is my first time owning an FMX car. I have had a 302 with C4 and 351W with toploader in my previous 2 Mustangs. I have a couple of questions, but will address one issue at a time.  When I pull the car out of the garage and into the driveway I've experienced the following symptom. The...

    Back Up lights/NSS wiring 73 FMX

    I have been working on trying to get the back up lights to work on the 73 convertible I bought a couple weeks ago. It has a 351C with an FMX transmission. There were no bulbs in the sockets, so I tried that first, but it did not work. I started checking and there is no power getting to the wire...

    351C timing/vacuum adv

    I bought a 73 convertible last week and had time to start inspecting and messing around with it today. I noticed, since the day I bought it, that there was no vacuum line going from the carb to the distributor. The distributor is not stock, it looks like an electronic ignition type distributor...

    C4 to long tail shaft BBF C6 swap.

    I am trying to figure out the best way to swap my C4 for the long tailshaft C6 I got to go with the 460 motor. I know I have the option of swapping the tailshaft for that of a short tailshaft C6, but the transmission show would charge $200. I could try doing it myself, but I have never messed...

    73 302 to 351C swap

    I have read many threads about swapping a big block, but have not found one for swapping a 351C. I know the bell housing pattern is the same. So what goes into a swap like this one? Are frame mounts compatible? Will the 302 radiator suffice? Any changes to suspension or steering? Thanks,

    351w block needs honing?

    A guy is offering this 351w roller block as part of a trade. He's like an hour and a half away so I have not seen it in person. All I got is some pics and was wondering if you guys can tell based off the pics, if the cylinders need honing. The guy says he builds engines for a living and this...

    D9TE-AB 460 swap

    I recently came across a complete 460 motor off a mobile home for $350. The guy said it had 48k miles and worked when it was pulled about 8 months ago. He said he even started it a couple months ago and it threw fire out of the exhaust manifolds. So I bought it... The casting number on the...

    Build up 302 or drop a 460

    I recently bought a 73 Grande with a 302 2v engine, auto tranny, power steering and A/C. I am in the process of rebuilding the carb because it wasn't really driveable with how the carb was performing. Anyways, I used to own a 69 Mach I with a 351w and 4 spd manual transmission, so the loss in...

    Hello from Houston

    Hello everyone. I recently (2 days ago) purchased a 1973 Mustang Grande with a 302 2v engine. It has front disc brakes, power steering, AC (currently blows air, which is not cold). It does not have any performance mods from what I can tell. It has a vinyl top which seems to have rust...
