I got it out of garage today. I did drive it up and down the driveway a few times just to check things out. Then.... I took it around the block with no major issues. I know the shifter needs some work and the brakes need re-blead. Man, that northstar is smooth compared to the 4 banger that was in it. Its also alot smoother the my 2.8 daily driver. Here are some pics outside. Does it look familar BubbaJoe ???

 Ok, I think I need a little tuning in the 7730 ecm. It has a little stumble off idle which makes driving a manual tricky. The problem is I've never done anytype of tuning. I programmed the ECM from Ryan hesses bin file and thats all I've ever done with ecms. I've done some reading on the subject but I'm not looking to get every HP out of the engine, I just want smooth running reliable engine. I tried to contact a couple of the poeple on this forum but it seems the all the Northstar swappers are on to bigger and better things. Is there anyone out there that has tuned a 7730 ECM for a stock VIN Y Northstar or knows someone that has, and is willing to share some information.
Any help is will be appriciated !
Thanks,

I'm doing some research on programming the ECU, in the mean time I hit the u-pull junkyard today. I knew they had a 88 fiero and wanted to get some parts before it gets stripped. It has a rusted cradle. Here is what I got.

The gauges are going into this project. I picked up the oil pressure and temp sensors and also the wiring pigtails. Since this is a 84 the wiring is going to be tricky. Its not prewired for all of the gauges. I already put in the tach and spedo, I had to modify and calibrate the tach for the 8 cylinder. The gauge pod is next (volts/oil). I'll be searching on the forum for the wiring.

Fantastic build first off!
I too am running a VIN Y Northstar, but sadly it is still transverse. I also had problems with Ryan's 7730 $A1 tune. His tune is for the Vin 9 and way rich for a Y. I dyno tuned to get the VE tables resolved but never got several other issues figured out. I came to the conclusion that there is just too much missing from the modified $A1 file. I am in the process of switching to a 1227165 ECM running OSE$12P and an NVRAM board. You might want to consider this - I will be posting my success.

I had another issue when I removed the flywheel. The bolts were alot looser than I expexted. I forget what I torqued them to, but I think I over stretched them. Here is a pic of one of the bolts I removed compared to a new one. You can notice the deformed threads.

Those look like two completely different fasteners.
Build is looking good, keep it up.------------------

not surprising, as one is old and one is new...
