It could be any number of things.
When the engine was put back together, was the cam timing confirmed to be correct? Rings gaped and placed correctly on the pistons? valve lash correct? Compression checked? Fuel Filter good? MAF and intake clean? There are numerous sensors that need to be hooked up and working too.
As was said, you need to find out what the trouble codes are.
Good luck.

thanks for all the replies guys, the biggest help here was that there was a obd2 under the dash, we pulled the code, got a misfire code and changed the distributor and wires, now we have good power, altough were still getting a misfire code, even though theres no feeling of misfire

Did you clear the code? You just need to pull the negative battery terminal off for a few minutes.
You can do a door pretty easily.... Just transferring over all the parts? They just bolt in. I haven't done a window but I've done pretty much everything else.

sweet thanks, and as far as they code, yeah we erase with the reader, and when its idling its fine, but as soon as we take off, it pops up, after that, we erase it again and it doesnt come up again for the the rest of the time we are driving, its also throwing a
PO136, i think, and thats the o2 sensor code so i dunno if thats causing the misfire code

so the o2 sensor is taken care of, it had to be tightened, but its still throwing that misfire thing, its really weird, we put new plugs in when we rebuilt, and just put new wires and cap on, anybody got any ideas?

Thats because after you erase a code your ecu goes through a diagnostic process that takes several miles before the light will come back on. The problem is still there when your light is off, it's just going through its diagnostic program. Good luck chasing down those gremlins.
