S.O.G.

YouTube Link Video shows symptoms. Drove the Z to a friend's house, camped out in it overnight, used the battery to run a fan. Battery wept and humidity made a lot of corrosion underneath, but the wires are good. Tried jumping it with another V8 before swapping battery, to no avail. Bought a new battery and swapped it out, same symptoms. Tried starting in P and N. Need to get multimeter out of storage to do more testing. As you can see from the video, it builds rail pressure in between 20 and 40 PSI, but then just keeps looping that. It never stops priming and never reaches the desired number. The engine never turned over and the starter always clunks. It feels like it's being stopped by something that isn't the starter or motor though. Fuel pump is in-line/out of tank. Absolutely no symptoms from starter or fuel pump prior to this, car was running well. FiTech is showing no codes but I have a battery disconnect switch that I use every time I park so it probably won't be showing codes. Has anyone come across anything like what the video shows? 02 Camaro LS1, 4L80e, Ford 8.8, FiTech EFI

Yea, it sounded just crazy enough to plausible haha, thanks for clearing that up guys. rsicard, that's some great info. After I get the motor swap working well with the 280 I plan to drive it for a while and get used to a higher powered setup then rebuild it when I'm ready for more. That will come in handy for later!

Sweet, that works for me! Just picked up the doner van last night. 165xxx miles, runs good as far as I can tell. Has a few minor issues, but nothing a gasket kit wont fix. Tranny shifts just fine. I was talking to a mechanic friend of mine and he said that the 4L80E wouldn't last in the Z because it was made to be under heavy load all the time. Since my z is sub 3000lbs he thought it would have a bad effect on the tranny. My logic disagrees with him but I'm not exactly qualified to debate transmission issues. Anyone want to share opinions or knowledge on that? He was leaning towards getting the 60 instead.

Alright, I have a 76 280z and an 01 GMC Savana 3500 with a 5.7L L31/4L80E I know the 4L80E can be stuffed under the car with some hammering and such to the tunnel but the L31 I'm less educated on. I've been looking at the threads here that relate to what I'm doing to get some much needed knowledge. What I haven't found - Info on mounting the motor in the bay Goals - 500hp (eventually) I'm guessing the torque will be around 550-650 if I make it to 500hp, if I'm wrong let me know - move the power band up in rpm (should happen with cams and the 500hp goal) - R230 rear end conversion (really just beefing up everything btwn the wheel and tranny, I drift so I'm not trying to deal with broken parts constantly) Once I start the swap I'll change this thread into a journal for what I'm doing/how I'm doing it but until then I'd like to get opinions or tips from people who have gone this route before me.
