Yes it's a 68 front valance. Sorry just seeing your post

I disn't look back to see what I've posted last but I am putting an ati damper on it this weekend. Then it's going under the knife for a 6 point roll bar

I put a two step on it

And turned up the boost from 9psi running a 10.80&125 to 13psi. Not sure on times yet

After the roll bar I'll be doing some testing before Drag Week 2015.

I down know if I posted or not but I made the cover of Car Craft March edition and 5 or 6 pages inside

Ok soooo I guess some stuff has happen since my last update

I upgraded the fuel system to an aeromotive phantom in tank set up. Bigger fuelline feed and return and new fuel rails

Put it on the dyno to turn up the boost and it wouldn't increase boost (I usedthe poor mans Home Depot "boost controller" ). I left disappointed because we couldn't turn it up

I went straight to johns out and we re routed the vaccine lines on the controller and waste gate and got it to make more boost ---- of you have to do this, something isn't right, but I did it anyway
It made more boost 18 total and pulled HARDDDD

So off to Drag Week 2015 we go

Sunday, Tech and test day was fairly uneventful. I did have to do some cutting on the rear fenders because the Pro's were rubbing.
Made a few partial passes but something just wasn't right. I could hear it pinging but the A/F looked fine

We made a few changes and made another partial pass and then decided to worry about it on day one

Day one rolls around and we make a couple passes and aborted all of them because of the pinging. But it was making some good 1/8 times. Picked up quite a bit since the upgrades and more boost

Finally I needed to make a full pass to get a timeslip so we could get on the road and mess with it the next day

Well the full pass was the last pass

After the 1/8 it let the magic out via both head gaskets and heads

It was late in the day and since I don't have stock thickness head gaskets I decided to put it on the trailer and leave it at the track and just follow the rest of the week in my truck 

We got back and I was deflated and let it sit for a few months

We thought it was just he drivers head so we pulled it and the cometic gasket was blown and the head was torched

We replaced the gasket and got another stock 317 head and slapped it back together

Went to start it up and water was being pushed out of the radiator...... ****!

So I pulled the turbo stuff off and pulled the passenger head off and low and behold it was toast too....

Luckily I bought a set of heads so I ordered another head gasket and put it all back together with the new head

Started it up and it smoked like a freight train but seems to be running fine so we went for a drive around the neighborhood and stopped at the gas station and it seemed to be easing up a little on the smoke so we jumped on the highway and went for a drive

It was running great. We had turned the boost down to about 10psi and it felt good By the time we got back to the house there was no smoke

We decided it had to be the back pressure from my home made log set up. It worked fine at 10psi but didn't like 18psi

So I jumped online and bought some twin turbo manifolds and decided I was upgrading yet again. I got the manifolds and they look awesome. But my car is running fine and I really want to drive it instead of tearing it apart and spending thousands of dollars to go twins just to cause a limited time problem. I can put it at 10 and enjoy the hell out of the car now. Or I can pull it apart. Spend a bunch of money and the couple times a year I want to race it will be faster.... But I drive the car a lot more than I race it It's a fun street car but it's not FAST The guys I run with have 8 second cars. My little 10.0 (hopefully) car isn't going to come close to hanging with them so I can leave it a 10.80 ish car and enjoy it NOW

Sooo I've decided I'm going to sell the twin turbo headers and just enjoy the car Maybe I'll change something later but honestly I probably won't. Down the road I may buy another car (lighter car) and build some thing but for now I'm just going to enjoy what I have
