rebuilt heater box, weak heat

hello everyone,

My daily driver died so i have been driving my 68 while i search for a replacement. new england winters can get pretty cold so i rebuilt the heater box, but i still dont get much warm air out of it. to provide some technical info about the car, i have a 1990 5.0 swap but converted it back to carburetor using a summit brand weiand warrior knockoff intake. im also running a standard rotation water pump. i purchased a brand new brass heater core from NPDLink, as well as the fitting that goes into the intake with the extension tube on the bottom. i rebuilt my heater box using a gasket kit and contact cement to glue the gaskets to their appropriate areas in the box (and yes, i put gaskets on both sides of the door flaps). when the car is up to running temp, the defroster vents are warm at best, and the vent that blows at your feet is pretty much cold all the time. i have provided a list of links to all the parts i purchased and used hoping someone sees where i went wrong. the car also got a new thermostat last year when i put the motor in, but only put a few hundred miles on it at most.

98 v6 mustang stalling when in drive unless gas pressed

I'm currently having issues when I put my mustang in drive it stalls out. If left in r n or p it idles fine. If I give it gas it will run fine in d and hit into n while stopping it will idle fine. Then I can drive like this but keeping it in drive without revving or driving it will shut down. So far I replaced the iac, the spark plug wires, spark plugs are fairly new, new battery, alternator, water pump, ac. I'm scatching my head and I'm thinking it's either the tps or speed sensor I have some pics please help me the stupid emissions are coming.

Installing 390 in a '67

Hey, I'm putting my engine in after a long long time and I can't remember the best method. I did it when I was 16 but don't remember how I did it. I trried putting the engine in without the transmission but the headers are in the way. I think I need to connect the transmission first but what about the headers. When do they go in. I'll keep trying but if any if you have done this recently I would love to hear how it went. Thanks!

1991 5.0 slow starting

I am trying to pinpoint the reason for my fox body's slow starting condition. It cranks every time, but is a slow crank and sounds like one of those cars where you're crossing your fingers hoping it fires up. I've done the below wiring upgrades mainly to support the new alternator, but was hoping it would help with the slow start condition:

  • SVE 130A alt.
  • Alt power wire to battery positive - 4 gauge.
  • Battery negative to engine block - 4 gauge.
  • Battery positive to starter solenoid - 4 gauge.
  • Body ground beside battery to a/c mounting bracket - 4 gauge. I don't know if this is the stock location or if it's even a good ground. This replaced a small frayed wire that was in place when I got the car.
  • Starter solenoid to starter - 4 gauge.
I have not tested the battery but it is only 2 years old. Replaced by previous owner when he put it up for sale. Spark plugs are fresh and clean, and the car has a new-ish ignition coil and PDI billet distributor. I have not messed with the starter or starter solenoid.

Car holds 14.3-14.4v at idle with all accessories on.

Even though it starts reliably, I don't want it to sound old and tired. Any tips on what I can test or troubleshoot to track this down?

1987 mustang fuel pump issues.

Car: 1987 GT 5.0 speed density motor
My fuel pump won't shut off when I turn the car on. And if I don't start the car fast enough, fuel will start shooting out some injectors.

I've replaced:
Fuel pump relay
ECM/ECU ( and it is grounded solid )
Fuel pressure regulator
Injectors

Nothing online I've read has the same problem where the pump is forcing fuel out the injectors. I've cleaned and put new injectors in and they held back the pressure for a moment and then it got forced out again. I'm at a loss.

Hanging Idle or is this Normal?

My 2005 Roush stage 1 has the Roush exhaust that has a great sound. I noticed the other day that when decelerating the car does not go to full deceleration until about 3 seconds after getting off the gas. The exhaust has a nice rumble at that point.
I had a 2002 GT that I inserted a small washer in the IAC tube that made it go to full deceleration instantly. On that car however the hanging idle was noticeable when shifting and general driving. The 2005 seems to shift perfect with no noticeable hang at all. It would just be nice if it went to the burble as soon as you let off the throttle.

Electrical Reverse lights/Cluster illumination not working?

Okay guys need some help here… I have a 1986 LX 5.0 that was converted from an AOD to a t5. All guages work however the cluster/hvac illumination only works when the car is put into reverse. Almost like it’s completing a ground at the switch. Coincidentally my reverse lights do not work at all. Verified I have power to the housings and verified bulbs were good. I’m completely thrown for a loop here. Also for more detail the Clutch Switch is still bypassed because I don’t see the jumpers, car starts without clutch in. So far I have put a new trans wiring harness in, a new reverse light switch, and a new headlight dimmer switch. Thanks guys, any information helps.


ALSO the car is on a holley terminator x system if that matters :)

Body alignment

I hit a car with the front passenger side the only thing that looked like it got affected was the glass fiber bumper support but now that everything is put together the driver side fog light is a little for out is there a way to fix it?

Also how to align the fenders or do I just push it in to bend it

Fox Stuck Power Steering Rack

Good Afternoon folks;

I hope you had a great new years. I need your expertise with a stuck power steering rack on my 93 foxbody (picture attached). The passenger side is pulling out fine. The driver side is stuck to the bushing and I am not able to pull the rack out of the K-member. My question is, do anybody has a suggestion to pull the rod out of the bushing besides hammering the rod out of the K-member??

I have had this problem for close to 1.5 months and any suggestion will be greatly appreciate it. I was thinking about reversing a power steering and alternator pulley puller. Again, please let me know you suggestions please.

Thanks
-Max

Supercharger questions

Trying to put this somewhat of a kit back together that I got third hand! Can someone point me in the direction of where these hoses are actually supposed to go to work correctly? The top one right now is going to a t to the intake manifold and the other end of it to the fuel reg?? The bottom hose goes to the intake pipe before the throttle body presently? Is that correct?

Camshaft choice?

I've currently got a bone stock 5.0 5-speed car that I use as my daily driver with a 2.73 rear gear. This is perfect for me because I do a lot of highway miles and it keeps the rpm very low, so its quiet and I get good fuel economy. However, I'm currently building another engine with ported GT40 heads and intake with a stock bottom end. I'm wondering if I should keep the stock cam since it will probably suit my needs better, or if I can upgrade the cam while still retaining the ability to cruise at around 1300rpm on the freeway without issues. I would like the added power of a cam but I would prioritize drivability because it is my daily.

Steering pump hose removal help

First of all, thank you everyone with the help with the threads Ive created. I dont have a lot of knowledge on these old ford cars either than a crown vic, and everyone has been super helpful with helping me fix up a 5.0 5 speed Ive wanted for a while. The only 2 things stopping me from driving this thing are the brakes and steering. Theres a big leak coming from the hoses going to the rack from them not being tight. I just installed my steering pump and now im trying to tighten these lines, but they seem almost impossible to get to without removing this steering rack. Anyone know how i can remove/tighten these lines without completely taking the rack down?
What an awesome community!
