Re: My 1983 Z28 H.O. gets LS1/T56 transplant (Write up and pics.)
That looks really nice. Not many early thirdgens getting genIII transplants (even genII transplants are rare). keep up the good work, can't wait untill this is done.

If I had the cash--I'd do an LS3. But I don't so I mod up the 350 TPI more and more
What times did you run with your old set up?
The last time I took the car to the track (1/8th mile), I ran an 8.71 @ 87 w/ a 2.1 60 ft. it spun the nittos bad (all motor run), I predict it could have went 8.0's with some traction.
Only ran nitrous for $$ street races. On the 125 shot I was neck and neck w/ my buddies pullied and full bolt on 03 Cobra 480-490 rwhp which would run 7.6's.

That is one beautiful Camaro! I'm all for the LSX swap, but I think you would have accomplished your goal of ten seconds w/out resorting to the LS1. Regardless though, awesome ride and swap you got going there! Good luck with it....

Nice, have fun with it! It is nice to have an older car that beats the pants off newer stuff and still looks good.. just realized mine was 26 years old now.

looking good, i'm about to do this with an 84 trans am 305ho/700r4 car, going single turbo lq9 with t56, mine will look stock on the outside except it'll sit abit lower and have different wheels

Sweet build, I plan on going turbo or blown in a year or two after the new camaro comes. waiting to see some one document a 3rd gen lsx turbo build.
I'm a little concerned cus the feul lines are kinda close to the headers, do u guys thunk it'll be ok if i wrap them in heat resistant tape. What have others done here? I'll try and snap some pics of them tomorrow. Thanks
You're not the 1st one to mention that, & from everything I recall, you should be fine doing that - at 60+ psi, the fuel probably doesn't stay near the headers long enough for it to be a problem...

Mine are wrapped with header tape and I've been driving it for a year with no problems.
Re: My 1983 Z28 H.O. gets LS1/T56 transplant (Write up and pics.)
Haven't got any responses to my previous post so I'm still figuring out what I’m going to do as far as my Torque Arm, I’m leaning towards modifying the drews cross member and having the Torque Arm mounted to the cross member. I just saw some pictures from a member here, so think that’s what I’m going to do.
Looks like I have 2 options (hope u guys don;t mine me borrowing your pics), cam-'s
or Ghettocruiser's
Anyone w/suggestions is welcome to chime in. I don't have a welder so I'm going to have to take this in to be done.
----------
Instead of going underneath the car, I installed the New Era CAI from an 04 GTO. I had to use adapters to run an 85mm MAF since it’s make for a stock 75mm MAF. I’m most likely just going to bolt on a K&N that fits directly into the 85mm MAF. It cleared pretty well since the LS1 radiator’s upper hose is lowered by about 3 inches.
(***pics don't show the adapter i used to run the 85 mm MAF)
I also bolted up the suspension.

Nice swap you have goin man! Regarding the crossmember... Either way (cams or mine) will work great in my opinion.
However...I wouldnt try to modify the drews crossmember to accept a torque arm. Im not saying it wouldnt hold, or you couldnt beef it up, but I was very un-impressed with the apparent strength of that thing. I was going to add a torque arm mount to it...but a buddy and I were able to twist that thing with our hands... That and it didnt fit. So I ditched it.
Someone with a welder and some time could fab a double hump up fairly easy I imagine. I wish Spohn would get on board and make his conversion x-member into a double hump with the torque arm mount. With how close things get, I understand why thats not easy though. Since every car is different.
I know that wasnt much help to ya... haha. Im gonna keep an eye on this to see how you make out though.
Re: My 1983 Z28 H.O. gets LS1/T56 transplant (Write up and pics.)
Z28FAST1 are you using the 3rd gen radiator with the LS1 dual fans? What type of mods were needed to make them fit, and what hoses did you use? I am almost ready to drop my motor in but I don't want to buy a bigger radiator unless its really needed. Awesome job on your car, good luck.

I actually used the 4th gen radiator, hoses, fans and power steering cooler. They all fit without any trouble. The reason I went this route was because the fans attach right up to the radiator brackets and I can also mount the A/C condensor for whenever I get my AC working. I'll post some pics later tonight.

That makes sense too, I just noticed that the 4th gen air intakes are modded to use the same air for the "ram-air" effect and figured the same air cooled off the radiator to some degree
I don't know if this has been asked but does the overflow reservoir have to be at a specific level in relation to the rest of the cooling components? You can't really tell but I have mine hidden behind the ac condensor about 10 inches below the radiator cap level.

Thanks, i haven't had a chance to post in a while, been to busy trying to get the engine turned over and the 4th gen cluster to work.
Good news is that I was able to get the car turned over and the 4th gen gauges to work using the serial data wire (I'll post more on this later). As I've read on the ls1tech, the engine would not build pressure until you actually turn it on. I have a 85mm Granatelli MAF which is not calibrated to the PCM so i think it was causing surging at idle and causing the motor to turn off. I ended up disconnecting the MAF and was able to get the engine to idle at 700-800rpm without playing with the foot pedal.
It sounds wicked with the open headers, I'll post some vids and pics this afternoon.

I used the 3rd gen radiator and installed 4th gen fans, the only modifications I had to do was put the fans in upside down and cut the tabs that stick on the sides off. Fits and works perfect.

Nobody responded to this, so I'll put my untested oar in the water:
The tank shouldn't be that sensitive to gravity. Coolant is pushed into it by pressure being released by the radiator cap, and pulled back into the system when a vacuum is created by cooling. It shouldn't have any effect.
