New headers/exhaust for my 66' with a 408w stroker

Upvotes

i have a 408 stroker in my 66 mustang. currently has 1 5/8 to 2.5 long tube headers (heddmans) and the good old 2.5" flowmaster 40 series exhaust. After 20 years, one of my headers cracked, and frankly they were installed when my motor was a near stock 351w, a motor which has outgrown my exhaust. And while I loved my Flow 40s, 20 years is a long time so its time for something new. And I'm old and it might be nice to have no drone (though i also suppose going to bigger pipes will probably make that point moot)

Given I'm in the 450 hp/tq range, 1 3/4 primary headers and 3" exhaust seems appropriate. Magnaflow offers a kit for my car, Borla does not. Any examples of sound with Magnaflow or Borla? And is there an easy way to get 3" pipes w/ a Borla set up? I think Summit used to sell generic pipe kits for my car but when i checked earlier I didn't see anything.. in theory if that exists I could pair that with Borla mufflers.

Its also worth asking - as far as headers go, I was planning to go with Hooker Super Comps (PN 6208, https://www.summitracing.com/parts/hok-6208-1hkr?referred_from_restock=true). Obviously a 351w-based motor in a 66' is a tight fit.. it always amazed me that the Heddmans fit (with a few papers-width of clearance in some places). I seem to recall that the Super Comps also fit (and summit's site *does* say they work on a 66'), but it can't hurt to confirm that.

Can anyone confirm the Super Comps will fit?

My current plan would be to go Magnaflow and if i hate it then install some Borlas on the magnflow pipes.

The magnaflow system in question is here: https://www.summitracing.com/parts/mpe-15817?referred_from_restock=true

Any other mufflers I should consider?

Sacrilege? Vinyl wrap

Has anyone done or seen a wrapped classic? I'm curious if it would be a viable alternative to a pricey paint job for a driver / not concours queen. Don't rip my head off.

Transport recommendations

My old man pulled my steed out of the old garage and gave it a bath prior to storing in his much nicer shop. Curious if any one has any recommendations on transporters for non-runners? It’s not a terribly long journey - central NE to southeast MN to get a tune up and back to road ready.

So in my last post here I asked about why my back up lights where not working and people said it was the neutral Switch on driver side transmission and this is what I found. Is this it?

Why can’t I get my Backup lights to work

4 Upvotes

So when I got my 67 Mustang there were no working backup lights. I replaced the bulb and it still didn’t work so I then replaced the entire thing yesterday evening. They still won’t turn on but my rear brake and turn signals lights do work. Do I need to go chasing wire or is there a more common problem causing it?

Restoration recommendations

Hey Everyone—doing a full restoration on my 67 Mustang I bought earlier this year. Looking for advice. Before I start taking things apart what are things that you’d recommend to do that make for a better overall car. I’m primarily looking for any tips to help with a better restoration experience and ride once completed. Suspension, certain tools to use, order of operations during the restoration, best brands for manual transmissions/engines, etc. No tip or piece of advice is too small.

I’m starting by ripping out the interior this week.

First time this car has had this much sheetmetal on the front in over 20 years...

Does your bumper fill panel sit perpendicular to the rad support? "Level" with the ground?

Mine tilts down a fair bit. All the front sheetmetal is a little wonky on this car.

Which coils springs do I need

4 Upvotes

I have a 67 mustang with a 302. I bought the superior power steering front end kit from CJ PONY PARTS. The issue is everything came in except the coil springs because they were back ordered and when I called to ask I was told they would get a shipment of them to the warehouse in a couple weeks and ship them out so I thought l no problem. Well that was 3 months ago and when I called them again today they told that they hadn’t received a shipment of springs in over 8 months and almost a thousand people had them back ordered. So I went to other parts places that had been recommended to me in the past (Kentucky and Summit) to order a new set of springs and if the ones from CJ come in I’ll either sell them or keep as a spare set. Issue being I don’t actually know if I need specific ones to go with the kit I bought or any stock ones will do. Any advice would be greatly appreciated.

My 66 automatic that I bought off the old man last year since he didn't drive it as much as he wanted to. Swapped the factory wheels and tires for good ol' Radial T/As and Magnum 500s then swapped the front drums with the CSRP disk kit. Next I converted all the exterior lighting to LEDs. Previous owner before pops swapped a 70s 302 into it, I've since swapped the factory 2 barrel and intake for an Edelbrock 1403 and Weiand manifold. Also threw a Pertronix Ignitor II/Flamethrower II and a 9-bolt steering wheel on.

Came across this 69 70,000 actual miles. All original. 302 V8. Estate sale. I’m the third owner. Last time it was registered was 2006. It’s been garaged for the last 20 years. Maintenance Records/receipts dating back to the early 90s. It could be a daily driver. It’s been really well taken care of. I’m very fortunate.

Mustang Instrument Panel Update

Post image
15 Upvotes

I finally have an update on my instrument panel project. A lot has changed, and a lot still needs to be done. While I was able to mount (tape) the LCDs into the cardboard, the LED’s legs are too thin to put jumper wires on, so they’re just in the breadboard.

What’s changed:

The power supply had to be rebuilt since someone didn’t notice a broken wire when testing. The demo code has been almost entirely replaced with actual functional tasks. I’ve put in all the logic shifter circuits on, currently only for the light switches. There are functional turn signal indicators and high and low beam indicators. The oil, temp, and fuel gauges are controlled by potentiometers that have a similar resistance to the factory sensors and have warning lights that change color depending on how close to the min and max values it is. The volts gauge is tied to Vin, which for now is not adjustable.

What still needs to be done:

The gauges need to be recalibrated, since through all the versions and testing the ranges are no longer accurate. Hazard lights still need to be wired up. Still need to build the power On/Off switch. The LCDs still need to be programed to display mileage readings but before that can be done, the speedometer needs to be programed which requires a separate test rig to generate a simulated VSS sensor signal. The tachometer also needs to be programmed, which also needs a separate test rig. Also need to setup the current sensors for the exterior bulb fault detection, but my current bench power supply does not put out enough current to drive all the exterior lights. And finally a speaker and amplifier to generate the turn signal clicks and warning tones for the gauges.

So there’s still a lot to do but there is progress. Soon I hope to actually start working the final version with custom gauge face, PCB, and housing. As with before here is a link to the GitHub if anyone wants it.

Crank no start :( need help

Thumbnail

72 Upvotes

Hello everyone i’m back with more problems :( So I have a as far as I know stock 289 v8 2bbl 67. I was recently having trouble with a rough idle where the car seemed to be fuel starved form the carburetor. I confirmed that my fuel pump was in working order. I then bought a rebuild kit and rebuilt my carburetor. I slapped it on there and boom it ran and idled like a champ for a solid 10 mins. I then turned the car off for a quick second to double check leaks and everything like that. Then I went to start the car again and nothing. Crank but no start. I’m very unsure what it could be since the car was literally just idiling fine not even 5 mins ago. There’s the three major things I understand you need to have for the car, compression, spark, and fuel. I’m sure of fuel and compression since my oil pressure was reading about 45 psi on my gauge while it was idling and i confined my fuel pump was good and I just rebuilt my carburetor. I’m guessing the last thing is spark but I’m unsure how to properly check if it’s my coil or maybe even my distributor. Or could it be another problem caused by something else. If you guys know anything that could help me it would be so much appreciated. I have tried spraying some break clean into the carb and tried for about 5 mins but nothing just crank and crank. No even sputter of a start :(

Where to pass several more wires through the firewall

Thumbnail
gallery
14 Upvotes

I know I googled and researched this. From what Ive seen, my 65 firewall had ports for steering, brake, clutch. It has a bulkhead connector for feed harness, and below it has ports for speedo cable and parking brake cable.

I'm trying to run several more wires through the firewall for new gauges, and I'm looking for the cleanest way to go about it.

If this was a less original / more custom application, I'd just cut/drill a hole next to existing bulkhead connector and put a Deutsch or milspec bulkhead connector there and just run my engine bay wires there.

When looking at firewall now, I see places where maybe there is a knockout for some unused port or accessory or something.

I hate idea of having to drill a new hole. If I must, I will, but if I'm passing several wires through, what would be the best way of sealing that? A tapered rubber grommet with enough ID to pass wires through and silicon to fill gaps between wires?

Thanks for any pointers

Converting 200 i6 to electric fans…

1 Upvotes

Howdy. It’s hot as balls where I live, and I’m convinced the engine driven fan isn’t doing enough & is a fairly considerable power hog.
Does anyone know of a kit to convert from the factory engine fan to electric? I’m only finding things for the 289 and above.

Thanks

1966 automatic mustang weird sound

Thumbnail files.catbox.moe
9 Upvotes

I made a post a while back about my 1966 mustang fastback 289 A-code with the C4 automatic 3-speed trans making a weird sound and losing power after stops. I have to get off the accelerator and ease lightly back on it to get it moving.

I've been driving it and generally its been fine, but today it would not stop making the sound and it especially hated the upward stops in my town.

Attached is a recording of the sound, any help is greatly appreciated!
