From what I have seen the fix for a LT1 is an LS1 swap. In the Ford camp we are working the 4.6 and the 5.0 hard to get to the current CMC numbers. The LS1's are just coasting at CMC power levels. If I could drop an LS1 in the 55 I would be all over it. I know this is not the answer you are looking for but I would not spend much money on trying to fix a LT1.

Pcm?
Check the float bowl levels
????? Float bowls... we are not talking carbs here. Maybe I about to look really dumb but I did not think I had float bowls with EFI.Originally Posted by Trublu
They are hard to find....

Were the dead cylinder's exhaust tubes getting hot? I've been fooled by the injector test before.
Disassemble the whole intake path, I had a MAF clogged with rubber at cresson. How are the O2 sensors? Maybe lost a sensor and is in limp mode?
Skipped timing chain??

CMC #50
Isn't that something that's only legal to do in Colorado at the moment??

Looks like your options are expanding.

So i was finally able to get the computer to read the PCM using a pretty basic program call Scan9495. It was extremely easy to use. The issue I was running into was simply that whoever wired the car did not care to reconnect the serial data wire so it was cut in the middle of the wiring. That took a while of banging my head against the wall thinking I had done something wrong with the software. I grabbed a few screen shots of the data. What stands out to people. I expected to have several fault codes. Unfortunately I thought it would save the list of the codes but it did not. I will screen shot those while it is logging tomorrow.
