anyone have any ideas....it did it with the stock motor and it did it with the next motor (we think) before it dropped a valve. we would just hate to get this motor together and have the same problem. we switched the injector harness already on the last motor. havent pulled codes yet since the car is still apart, but we will once its running

well never know until we get it back together. well try a different distributor and if that doesnt work we will get a set of noid lights and check the injector harness. we can also check all the injectors

A far shot, but see if you can swap computers. Have you checked compression on the 4 and 7?
