Is that a R200?

It is a surging idle ONLY when the car is rolling (and not under load) and above 5 or 10 MPH. At a standstill, it is purrrfect! I can definitely hear the LT4 cam I installed. Nice and pleasantly lumpy. That's what leads me to beleive it has something to do with the VSS input into the ECU. It knows for sure how fast (slow) the car is moving. I'm guessing the IAC is affected/controlled somehow by the VSS. I'm almost positive the vacuum lines are tidied up. And yes, the IAC is located just under the throttle body in front of the air intake. Thanks for the compliment on the ride. I know most people don't care for the 2+2's but when you remove the bumpers, they have an eye-catching look. This one is nearly body perfect and VERY rare in Wisconsin as most of them rusted away and broke in half. I wondered at times why I went through the pain and expense of V8-ing a 2+2, but man, I LOVE it!!! The car was my Dad's and has been in the family for 30 years! I'm 42. The attached pic shows what the car looked like for 25 of those 30 years. Of course it was a LOT cleaner. This was a shot I took after I removed it from 10 years of storage.

Let me begin by giving thanks to all of you who have taken time to post questions and responses on this site! Your input has been ENORMOUSLY helpful to many of us who are not as automotively gifted as many of you are. Without some of this information available through your writings, I would not have a drivable LT1 equipped Z. It is far from finished, but it runs and I have put about 200 miles on it to date. I am hoping some of you gurus could speculate on what might be my LT1 killing problem. What I have been able to determine so far is the following: I can be cruising at any speed (10 mph-65 mph+)and I can take the T56 out of gear and coast without a problem. I have the computer set for an idle RPM of 800. The engine, while coasting, will oscillate between 800 and 1000 RPMs about once every three seconds. Fine. I don't like how it does that, but I will problem-solve that later. At least it stays running. When I coast to a stop either with brakes or just a stop through running out of forward progress, the engine with sputter and kill. It appears to start having trouble running at 5 mph and less. The interesting thing is that this happens if I come to a stop in reverse too! It does not matter whether I have the car in gear or not with the clutch depressed. Whenenver I come to a stop, I have to feather the throttle to keep the motor running. After the engine kills, I can restart the engine and it fires right off and runs like a champ (until the next stop sign or light)! Man, I love the power, the sound, and the performance of this V8 Z!!! I am running without a MAF and using speed-density tune. This thing runs perfect in every other way! The motor will idle just fine when first started or restarted after a kill event. Do I suspect a questionable IAC? MAP? IAT? It is a '95 LT1. I have no SES installed yet. I have a USB cable to a 16-pin OBDI connector but have not had success getting my computer to recognize the USB connection on COM1 to determine what or if I am throwing a code(s). Please let me know if I need to throw out more knowns for anyone to take a guess at what might be my problem. Thanks in advance for any and all suggestions!!!

What year(s) Taurus (or Thunderbird) fans work well?

I would concur with this. They have been fine to work with for me too. I am in the midst of a conversion and I am using their kit. Of all of the items I've had to work with fitting, the JTR parts have been the closest and have made the critical engine placement as close to perfect as can be. They were quick with me on the phone because I got the feeling they were busy. In my oppinion, I would like them to be busy and in business for many more years. I would do business with them again.

The factory LT1 exhaust headers will not fit. They make contact with the steering shaft. I am doing the exact same project. I've installed a '95 LT1 and T56 into a '77 280Z. I bought the JTR block-huggers made by Sanderson. I don't know anything about California vehicle emission laws, however.

If using an F-Body water pump ('95 Z-28), where do you run the "engine coolant bypass" port to. It is the exit from the water pump in the lower right portion. Also, what does this do? Thanks! Eric

Did you use the GM Performance parts A/C Delete pulley? I was going to order one and just don't know whether it will hit the frame rail. Thanks! Eric

Yep, I had sandblasted and painted mine all up too! Bummer! My progress is just as you see it. Not much farther than yours. Next step is the T56, Fuel lines, ReDoing brake lines... LOTS of tedious work! Some of these guys are brilliant, experienced, and judging by their pictures, real artists! Real inspirations!

Here are a couple of pics that were taken last nite (late). It is very much a work in progress. I know these exhaust manifolds fit. Also, this is my first attempt at uploading a pic so hoperfully it goes well enough for them to appear.

Looks to me like the exhaust would have to make a 90 degree bend downward and I don't think there is enough space to come off the exhaust manifold and enter the tunnel. Made the same mistake myself with some factory LT1 exhaust. Only they hit the sterring shaft. Had to go with headers from JTR. Just put them in last nite. THEY FIT!!!

I am NEW here! I have searched and searched the HybridZ site and have not found a clear solution for locating an alternator on a LT1 when not using AC or Power Steering. I would rather not use all the bypass pulleys and have the alternator up high (unless absolutely necessary...). I was hoping to mount the alternator low and bought the very bracket other HybridZ members here have said does not work. They are absolutely right! I found this out after I had painted mine all up nicely and now it is not returnable. I wish I had found this site earlier! It seems experience says that the Corvette mounting hardware is the way to go. I already am using the Corvette balancer. Does the Corvette mounting hardware move the alternator up high again? I have not seen a diagram yet of this setup. This is likely because I have not looked for one. So the question is, what year Vette are the parts from? Or are there other solutions? A pic or two of one installed would be great to see. Does anyone here have one (or more) they could post? I wanted to post a pic of my progress, but I need to downsize the pics. Thanks in advance for any help you guys can give... Eric

I'm mid-way through a LT1/T56 swap into a '77 Z and have spent over $3,000 on engine prep and various parts (I've owned the car for over 10 years). This is not much compared to what you could spend. It is a major undertaking in time and money. It is my thought based on you writing your budget is tight and your lack of information at this point, this is not something you want to tackle before your budget becomes larger and you've had time to do more research. Check out Jags That Run. Google it. They've got a nice swap guide. It is worth the money and will answer a lot of your questions. Good luck!

Zed (that is my bird's name too), what did you use for a clutch master in your swap? I am doing the same swap you did ('95 LT1/T56) in my '77. I'm looking at the Tilton 75 series 7/8". Eric

That looks REALLY good! I want to post some pics of my Z. Just need to figure out how to do it. '77 280-Z. I am in the middle of an LT1/T56 conversion. Wish I had a fantastic paint job like you've got!
