Well went to fire up the new motor today and I'm having a weird problem... When you start it the motor will begin to run but once you try to bring the RPMs up it'll just sputter out the carb. I felt the header tubes and noticed it wasn't firing on #2 and #8 so I checked for sparked and they werent firing. So then I changed the 2 plugs and wires and they started firing but NOW #3 a #7 don't fire! It seems no matter what this thing will only run on 6 cylinders at a time. Car has a MSD 6AL and Pro-Billet distributor (both new). They are all hooked up properly and worked perfectly fine 5 months agoon the old motor. The dist is in right it points right at #1 when its at TDC and the firing order is also right - I checked it all 5 times. I've played with different timings and nothing helps. I also thought maybe the rockers were too tight so I redid the lash and still nothing... I havent had much of a chance to play with it so maybe you guys could give me some ideas of what could be wrong? I don't want to keep trying to fire this motor up because I have WAY too much money into it and dont wanna risk hurting it.

Sorry for the ramble I'm tired and confused hopefully it makes sense...

Thanks,
Chris

Did you get this figured out? I'm having the exact same troubles.

I took out all the ignition crap and put everything back together nice and neat and it worked fine. My problem was 1 plug wasnt firing and my timing was waaaay retarded.
