Thank you
Everyone over at LHforums.net said it looks super clean too. đź‘ŤHow much does it weigh? My 300 weighs 3600lbs.
Thank you.

I doubt your 'Cuda weighs 3500lbs...
A freaking GALAXIE with a 390 weighs 3800 with driver!
EDIT: Also, don't expect the 4-barrel to add 55hp.
The 235hp motor had 10.5:1 compression and a more radical cam.

That's what I found
3200-3500lbs, and I have the 4.7L V8
Ah, I forgot about that. It will still add quite a lot more umph to the engine at least

Not if the way it's cammed keeps it from breathing past 5 grand.
Which it will.

My point being when I step on it, there will be a noticeable difference between the two and four barrel. I'm not looking for it to be a race car when I add the four barrel, I just want a little more power with the little money I have to spend.

Not necessarily.
The only real gain you'd get from a 4bbl is possibly better fuel economy, if it's kept fairly small. 500-600cfm at most. You MIGHT get 5-10hp out of it if you're lucky, which will put you around 160 at the flywheel.
Your car makes peak torque at 1600 rpm... Power at 4600 IIRC. It doesn't need to breathe much.

You're such a killjoy
Now I get to be happy that I'm looking to spend the rest of my money on a four barrel and manifold that apparently won't do anything
I guess it's better then being ignorant, but I was told that adding a four barrel and a new manifold would make a noticeable improvement.

Sorry mate.
Personally, I'd look around at swap meets and the like to find an intake + carb and a cam, then get the block decked. (If you can find a cheap set of aluminum heads with a smaller combustion chamber, go that route).
Remember, if you don't have to hack stuff up to install something, it can always be restored to stock if you keep the parts.
- 3,770
- Boss-Barracuda
Sounds like a good idea, and I'm definately going to keep all the stock parts.
I found a car on ebay that has some good parts here, and I shot the guy an email to see if he'd be willing to part anything. It's really quite sad if you look at it.

It has a reserve.
If it didn't, it'd be worth it to try and nab.
Also... Unless there's a decent set of 273-specific performance heads out there, you may well be screwed. The 273 has a much smaller bore than the larger motors, so you'd run into the same problems bolting a 318-360 head onto your 273 as someone would have bolting a 427 Side-Oiler head onto a 390.

I managed to get the roof of her moms mustang sanded and buffed. Also sanded and buffed the hood. All of this is including in between the stripes which I had to use a sock because there was no way to buff using the electronic buffer. Also sanded and buffed the passenger rear quarter.
Now I also have the paint to finish the vinyl interior and make it match the car. Still a lot of work ahead but I am making some pretty good progress.
The rear bumper brackets came in on friday so now I can install her rear chrome bumper some time after I am finished buffing everything out.

I will try to get some before, during, and after pics up once the car is closer to finished. My goal is to at least get the body all sanded and buffed out by tomorrow wednesday the 2nd so I can bring the car to her on thursday the 3rd. I will just finish painting the interior after the 4th of July holiday.Next time you work on it take some pictures. Picture updates make things a lot more interesting then a block of text
Last night went real well. I finished sanding and buffing the entire rear of the car including the trunk lid, around the spoiler, and all around the stripes.
At this point I only have the passenger fender and passenger door to sand and buff plus a little on the front of the car. Then I can install the antenna, Mustang emblems, and rear chrome bumper.
Tonight I am going to try to bolt on the rear chrome bumper then sand and buff out the pass door. Getting very close now.

Got my brake tag (state inspection) ($10).
Also bought a new air conditioner condenser yesterday
(that was expensive).
Doing an oil change later today.
Getting transmission fluid flushed asap.
All in all the car's running well but I'd like it to be better.

screwed around under the hood, trying to find the negative side of my distributor, so I can hook up a Tach.

Haha that's why I love the GM HEI distributor, just find the free spade terminal off of the ignition coil and plug in the tach.

Tried to figure out why it seems to cut out for a fraction of a second at random times usually while cruising, before kicking itself back into life. I'm thinking something might be wrong with th fuel regualator, and sometimes it fails to supply fuel to a cylinder, and then this happens. Any ideas guys?

Hmm...
It's gotta be electronics issues. The fuel pressure regulator does just that, regulates fuel pressure. Doesn't control fuel flow into the ports, that's the ECUs job.

My computer has errors too, you can tell because when you rev it at stand still and watch the revs drop, they don't drop smoothly back to idle, they drop dodgy if you know what I mean.

When is the last time you changed your spark plugs or wires? I would look into that first then check your fuel filter.
Last night I made some more progress on Heathers moms mustang. I got the passenger door all sanded and buffed. Then I went onto bolting up the brand new chrome bumper. Thats going to require cutting some of the sheet metal on the back of her car to make it fit. They didnt sell brackets for a 73 so I had to buy 71-72 brackets and will have to do some cutting. Didnt want to but its the only option I have. The other bad news is that there is a 80% chance of rain. I guess if I have to I can pull the Camaro out of the garage and put her car in there for the night to get all this finished up. Could be a late night.
Tonight is my last night so I need to get that passenger fender and front clip all sanded and polished then I can bring it to her tomorrow, Thursday the 3rd.

Interesting that the 71-2 bumper brackets are much different than the 73 jobbies, seeing as the Mustang was just about the same for all three years, wasn't it?
Or is it the difference of impact regulations?

Yeah they are almost identical. There is a bolt in piece of sheet metal the runs from the left side all the way to the right side. Its basically a metal cover to hide the brackets and hide the area behind the rear bumper. That is the only thing that I could see that was different while I was mocking up the rear bumper. I will just have to make (4) 1" notches to make it fit.
Not usually a big deal but since the car is painted thats going to expose some metal. I will just spray some primer on those little exposed parts for now then repaint them next year. Next year I have to pull the engine to paint the engine compartment. So while I am doing that I can paint these parts. Plus by the time next year rolls around I am sure the paint will have some scratches and chips from mother nature.

Pugs and wires not so long ago, and they are also now higher performance, longer lasting ones. Fuel Filter has also been done. We tried cleaning the injectors/heads, but it still happened. It's not a common thing, but these past couple of days seems to have gotten worse. I used to go weeks at a time and it would only happen once in like a month. Considering it only normally lasts about half a second or less I wasn't too worried. Until the other day I had one that lasted 2sec! Now I've had it happen 3 days in a row.

Fuel pump.
It'll start as bucking and then progress to cutting out and forcing you to let it cool off. Fuel filter may have clogged itself again as well.

I would change the fuel filter, then try cleaning the injectors, check the plugs and gaps, check the plug wires. Basically look at anything related to fuel and air and clean it, especially electronics.
If that doesn't solve the problem, at least the car will run a lot better whenever you do find the real problem.
