Hey man,
I have used the stock fuel hard lines for now, I believe all 12A cars had similar sized fuel line. I will let you know if I have any issues regarding a lean condition under high load. I bought a walbro 255 lph fuel pump and modified the stock fuel pick up to attach it. I need to add a support piece to hold the pump in better so it doesn't fall off when cornering/drifting but I have not done so yet. If I take my tank apart this weekend I will take pictures.

Some updates.....
Had to remove the cruise control throttle position sensor so I could achieve full throttle
Car had been running ok, but would randomly start backfiring real bad, I found that my plug wires were not routed adequately so I replaced almost all of them. I found 3 or 4 that were burned bad.
After that the car ran 300% better, pulls super hard now. I was honestly underwhelmed by the power but I must have been running on 5 or 6 cylinders
Last time I drove the car it would not start after a gas station stop and then was backfiring/breaking up really bad. I barely limped it home, but it started fine after sitting for a few hours. Checked out the coil and decided to replace it. I also spaced the coil and ICM off the head so they will stay cooler. I replaced the plugs and am checking for any other exhaust leaks. I hope to test drive this weekend again.
I suck at taking pictures, I should really try to take some good ones this weekend

Have you replaced the optispark unit on that engine yet? The earlier versions of those things weren't vented and they get all wonky if they got wet. Before I changed mine out I was seeing similar problems. I experienced the same issues you did with the plug wires too, I had to custom make a loom that would work for the headers I had.

Small update:
Putting proper suspension on, I am getting 350 lb springs for the rear (Nascar takeoffs, 5.5" x 9.75") and 450 lb springs for the front. I also ordered a coilover kit for the front as well.
Taking the front struts off and apart I discovered I still have the stock struts, I am going to put really heavy oil in them and see how they do.

Thanks for the post, car runs good, but I have a starter issue when it is hot. I am redoing the battery wiring, but I think it is the starter itself. Don't give up on your project!!

Does it even overheat in five minutes of a cold start? That is pretty fast for any cooling system issues. Is your guage accurate or have a thermostat problem maybe? If you have a head gasket issue there are several ways to check. An easy one would be to buy a block testing kit from the parts store and check for combinations gasses in the coolant. There should also be a measurable loss of coolant if they are leaking.

It will start fine and idle fine but as soon as I put load to it, it overheats. I heard lots of gurgling as well after it overheated. I do not have a gauge on it. I should probably try the block test kit because I was able to pressurize the cooling system to 16 lbs. I need to pull my thermostat

nice work. I especially like that tranny conversion plate!
I went to put my tranny in and saw that fork going into the header and was like WTF granny said it would fit. LOL

I found the hubs and brakes off a car from Craigslist that was local. They do not make the hubs anymore unfortunately so you have to find in a junkyard or on eBay, or partout car. 86-91 should have them.
