Okay everyone here goes. The lower end was from a caprice classic police car. The alum heads from the orginal motor were put on the donor motor. Now one thing that drew my attention is the cam........are they all the same. As far as lt1s??? If not than that could be an issue im having right? Computer getting confused maybe? And yes i shouldve checked fuel pressure right off the bat. I assumed it was fine seeing the car runs good just has no power.
Anyway, did you change the knock sensor in the block? I belive the ones in the B-body are different and may be cause some issues around ignition timing...

I.do.not know that this is.all coming from prev owner who did it. It dose not show any knock sensor issues on the scanner. We even reved it hard a few times to see if it was showing anything. Im lost but thankfull its not my cam causing all this. Just spoke to the previous owner and he said he did a fuel filter right after changing the motor. Sounding like a dying fuel pump..... any more advice???? And as far as o2readings ill hook the scanner back up and post back readings.

I think Mrmint put it best.......
Went back over all your posts. You neglected to do any of the easy tests suggested and went right for the complicated stuff. Fuel pressure test was listed first and done last and appears to be your issue, as well as possibly bad O2 sensors, which both will make that car run bad. .
Oh and while I'm on the subject. If you got it back from a shop and it's still no good, what did you take it to them for in the first place? Shouldn't it be right?

i did a fuel filter just to be on safe side as sugested above and its still the same, whole pump was ordered and will be here today at 10am. i have the day off from work so ill be doing the trap door mod once the pump is here.
And the o2 readings were lean bank 1 and 2......this could be because of lack of fuel im thinking? regaurdless the pump will be in and we will go from there.
As far as the shop its a good friend of mine who owns it and works on my car. He is an honest person and only trying to help. everything he's done he has shown me why it needs to be changed weither or not it was the issue im having was sure going to be an issue in the short road. I have no regrets on taking the car to him. We both got confused on the spark advance readings the scanner was giving us thats why we went ahead and made sure cam timing was correct seeing the prev owner of the car was "un sure if he did it right". Moral of the story is i most deff should have checked fuel pressure from the start thats a huge fail on my half. But we learn from our mistakes every day right guys! And thanks again for all the help!

Well what was causing the low fuel pressure??? Was it actually that low? Could it have been the FPR we talked about a while ago? If it is the cause of the problem and it was not changed, see how it could still be running poorly?
Perhaps I didn't make this previous post clear. If the diaphragm is ruptured, it will lower the fuel pressure.
Did you or anyone else ever check the FPR?
I say MAY cause there are 2 other things that can create a long crank situation also. If the FPR has a hole in the diaphragm, it can do the long crank also but it will also cause the engine to run poorly. Do to dumping fuel into the intake via the vacuum line. You can test this by using the vac line to draw a vacuum on the FPR. If it does not hold a vacuum, the diaphragm is ruptured.

the only thing i check on the fpr was pulling the vac line and seeing if fuel was in it and which it was not i hooked it back up. If it was ruptured wouldnt it go into intake from the vac port????

When you check he 02's make sure they are good and warmed up. You want the reading to be all over the place and between 0xx and 9xx. Changing very rapidly like this 128 845 396 274 762 582 145 and so on. You really should fix the fuel problem first and then test them as stated.
