200,000 mile GT build

[Akurma]

I appreciate that! The car spends most of its time sitting in the garage waiting for me to build and rebuild the engine. I cant leave it well enough alone. I get an idea for an improvement and i act on it making the improvement a 5year process.

I dont believe it was a northern car, I bought it local, but there is a nice rust hole on the trunk floor between the fender and spare tire well. I fear its in the beginning stages of what yours has turned out to be. So one day ill have to investigate the cancer damage and possibly correct why its doing what its doing. Seeing your handy work gives me hope that it wont be as bad of a repair as my mind is making it out to be.

I feared my repair was going to be terrible but once I got in there it was pretty straight forward just time consuming. I will say that having a replacement part made it significantly easier. Do yourself a favor and take a flashlight, pull the trunk carpet and side panels out and shine the light down the driver and passenger side where the trunk floor drops off. if you see light on the ground below.. you got a rust hole somewhere. If no light is seen, then you now have peace of mind

Hey I found your post on Modded Mustangs and replied even though it's an older post lol. What did you end up doing?

Mine has 196 k on it and recently put the 190 k engine out of my wrecked 95 in the 94 Cobra I bought in 2017. The previous 302 sig:
Ed RPM 2, .525 211/219 @ 050, TF 170, 24 lb, 75 MA, 70 TB, Mac 1 5/8 shorties, Basani X, flowmasters, 3.55, and a tune

current sig:
94 Cobra Ed RPM 2, .525 211/219 @ 050, TF 170,, 24 lb, 75 MA, 70 TB, BBK 1 5/8 LT's, BBK X, Pypes bomb free flowing catback with 3.5 tips, 3.73 and tuned.

The car feels pretty good overall but out the gate I'd like it to be more peppy. It's decent and the LT's really wake it up when you step on it especially and though I'd love to get more out of it, I'm not really desperate to do anything right now. I did a compression and leak down test before putting the engine in, I believe I did the leak down, and the numbers were fine. If I had a strong conviction that I could get at least 30-50 k miles out of putting on a blower I'd likely do it lol. I don't track the car and it's really just a weekend streetcar as I have an 04 Cobra too and another 95 that's running but I want to do a 331 if I keep it. Actually my son just traded his '18 300 S for a 21 scat pack Saturday and my goodness I'm already in love. I can see getting one of them and just leaving the other 95 for later down the road to build or even sell it.

What gearing do you have in there?

3.73 but I actually have a 3.55 rear end that came out of the wrecked 95. I'll edit the previous post

I don't know what made me visit this post and your car is a modular engine 4.6 and I have a push rod lol. So if I remember when I get back to work tomorrow I will be able to be opening post and see what made me reply to this thread. Only asking too first round stuff about opinion and such on a matter for mine.

Went to Summit today and there was an SN95 in the parking lot with no hood and a big turbo sticking out. Dark blue

 

[Akurma]

It's been ~95*F here in Pennsylvania for the last two or three weeks with no end in sight. Figured it was a good time to finally charge up the AC system. I replaced the AC compressor, condenser, Drier & hoses (all but one 1999 specific hose that's been discontinued) when I put the motor back in. So wasn't sure if I'd have a leak but 20 minutes on a vacuum and leak down test it passed and took the recommended 2.2lbs of R134a and is ICE cold

She gets dropped off for state inspection & Emissions on Monday!

 

[Akurma]

Absolutely gutted.

 

[badass98svt]

Damn man. How'd it happen.

Valve spring failure?

Looks like classic valve springs....non ovate wire, non beehive. I too have failed broken valve springs and they were not beehive

Honestly no idea! I had been daily driving it for the last two weeks and it was great, no signs of issues or anything. Went out to lunch, was idling in the parking lot at work while I got situated in the car for about 15 seconds and then it just it made a loud THUNK and immediately shut itself off.

Yep, valve spring split into two pieces. They were PAC racing valve springs. Not sure what I'm going to do, obviously have to pull the head off and see what the cylinder looks but it definitely kissed the piston. Not sure what the brown spot is on the cylinder wall. Debating a coyote swap depending on cost to fix this.

That's crazy. I wonder what happened. Stock cams? Stock long block?

Not 100% sure on cams, was told they were Anderson F52's but cant find any markings on the cams besides "Left 660" on the pass side and "Right 660." PAC racing springs. And unfortunately not a stock long block, forged rods & pistons in a Teksid block.

Reached out to a few placed for a quote to have both heads gone over with new springs and fix the damaged valve area. waiting to hear back on them. Hoping the cylinder wall is ok and just needs a new piston but wont know for sure until I pull the heads off.

Damn shame, that's a really nice bottom end too. Keep us posted on what happens. I have my whole green car engine etc. Out of my car going through the heads now too. It's frustrating at times.
