What's the tolerance of your scale?

I don't know what the tolerance on it is. However, the issue was the pressure plate. It was 42g out. They had to drill the weights to get it in balance. They also marked it for me so that I can install it in the same postion that they balanced it. I picked it up tonight and will be putting it back together this weekend.

Good luck Ron. You need to hurry up and finish it. My dad has some $$ for you to drop his 428 into his Mach.

Thanks Adam. I'm getting ready to start assembling it now and I'm hoping to have it built today and then drop it in tomorrow if the winds cooperate. Tell your dad I'm in and we can set up a weekend to do it as soon as I have the Cobra done.

I have the engine done and ready to drop into the car tomorrow.

I only worked on it for about 4 hours today but I got the engine and trans back in. I about another 2-3 hours worth of stuff to do before I'll be able to start it.

It's done and no more vibration! I actually finished it last Monday but when I started it up it had a lifter tap and was missing. It was dark by then and I was pissed so I called it a night and went inside. With the rain I and other things I wasn't able to take a look at it until today.

So this morning I pulled the TB and elbow off so I could pull the valve cover. I found that the exhaust rocker on cylinder one had backed off so I torqued it back down and put it back together. I started it back up and the lifter tap was gone but it was idling a little rough. I took it for a test drive and it was misfiring.

I then pulled the plugs to see how they looked which they all looked fine and did a compression test. All cylinders were about the same and had good compression. So I put it all back together and took a look at the MSD box. I've had issue with the box before so I bypassed it and went for a test drive. Still had the misfire!

Out of frustration I decided I would try the old plugs. I just bought new ones when I put it back together this time because the old ones which only have 800 or so miles looked a little fouled. So I put the old ones back in and would do you know, it was the new plugs. I don't know which one is bad because they all look good but at least one is.

So the car is running great, well rich but other than that great. Now I just need to come up with the money to get the final tune and see what she puts down.

Nice Ron. Congrats. Was it worth it?

Not sure until I get it tuned. All I know is it feels a lot more powerful than it did before. I drove it over to Phil's tonight and getting on the freeway it broke loose at 3/4 throttle in third. There's bad news though. The check engine light came on and the codes are for EGR and coolant temp sensor. I'm not sure why because they are the same as they were before but it's been the theme of this build.

Its the curse of the Santa Fe.:rolling:

This is so much worse than the Santa Fe. I've already pulled the engine and trans twice as well as built the engine twice.

I found a broken vacuum line inside some loom that was causing the EGR code. The coolant temp was working but the connector was a little loose so I crimped the connectors a little and that took care of that code.

Ouch. :suicide:

I emailed Steve this morning and just heard back. I have an appountment to have the Cobra tuned tomorrow at 1pm. I'll post up the results tomorrow.

So I have good news and bad news. First the bad, we were not able to complete the tune due to maxing out the MAF at about 5200 rpms. I have an 80mm Lightning MAF and need to go up to a 90mm. Luckily Guy had an extra 90mm housing so I already have that. I just need to get the elbow and filter adapter for it.

Now for the good news. With Steve stopping the pull at about 5400 rpms the car still made 455rwhp. It made peak torque at 4300 rpms which was 474rwtq and at 5200 it was making just over 460rwtq. Steve said there is still some more in it because he's pulling a lot of timing out above 4000. He thinks peak will fall right between 470-480 on the pump gas tune and thinks that it will make 520rwhp and 500rwtq on race fuel.

I quite literally live in a sea of mustang parts :/

Now if you can just remember where you put everything.

I have a loose recollection of where everything is.

I have an issue ever since I put the engine back together that it has been using oil. A lot of oil lately, like a quart every 700 miles. I thought that maybe the intake gasket was leaking because I reused the gaskets. I was going to wait until I finished Andy's car before I tore it down only because I am also going to be installing a new cam but I decided to start on it today. I started pulling it apart and the intake gasket was leaking which I'm happy for but I also found sludge built up in the rear water passage on the head. I reused the head gaskets as well and I think they were leaking too.

I needed to finish lapping the valves on Andy's heads so that I had room on my work bench to put my heads. So I stopped working on the Cobra and finished Andy's heads this afternoon and then went back to pulling the Cobra apart. I finished around 7pm tonight but didn't take any pictures. We're supposed to be getting the crank, bearings and rings either tomorrow or Tuesday so I'll be building Andy's engine at night this week and then installing it this coming weekend. After that I'll get the cam changed in the Cobra and then pick up new gaskets to put it back together. I also have every thing I need to install the 90mm MAF except for an air filter so hopefully once I have it put back together I can get it to Steve to have the tune finished.

I have an extra 4" filter if you need one. Do you mind if I have your old 80mm housing for the race car?

I'll pick a new one up from GTR but thanks. You can have to 80mm housing once I install the 90mm.

Ordered my FelPro MLS head gaskets today.

I need to order some as well.

I found a guy on ebay selling a pair for $130 so I bought them. Summit has them for $88.95 each.

:popcorn:

Damn that's a come up. My cost it $80 each

I know, plus he was offering free shipping.

I worked on the Cobra Sunday and got the cam changed and the front end put back together. Then I spent a lot of time sanding the deck for the new gaskets. I received the new head gaskets but I need to lap the valves before I install the heads because I have a couple that are leaking now because of the lean condition with the intake gasket. I aslo found that almost all of the valve seals are off and they are Viton style seals. That would also contribute to the oil burning issue. These are the only pictures I took from yesterday.

Looking good. Curious to see where you end up power wise when done.

Same here. I don't think it will be all that much different than the last time I went. The only thing that's changing is the cam, the rest of the issues shouldn't have had that much of an effect on the WOT pull.

Bring me the can so I can t

What?

Tonight I finished cleaning up the other head and lapped the valves. All I need now is the correct valve seals so that I can put them back togehter.

Disassembly.

Looking good Ron! See you sunday!

I picked up the new seals today but unfortunately my home A/C stopped working tonight. So I'm going to see if I can figure out what's wrong with it and if I can't then I'll have to call a heating and air service so it might be a day or so before I can get back the the heads.

i can help out with the a/c if you need it.

That only works if you can come out tomorrow.

Had time to install the seals and reassemble one head last night.

I took a half day from work today so that I could take a look at my ac. It was supposed to be almost 100 degrees and up to 106 by this weekend I needed to get it fixed quick. I was able to figure out what the issue (blown capacitor) was and picked a new one up this afternoon. Total cost was $31.62.

So after that I finished assembling the other head, then cleaned up the gasket surfaces and bolted the header back on. I was able to get that head bolted onto the engine before it started to get dark. Tomorrow I clean the gasket surfaces on the other head, bolt the header on and then install it and whatever else I can get done before it gets dark.

Here are the only pictures from today.

Cleaned head.


Head torqued down.
