I have a 4.3L Chev in my boat and just had someone replace the intake manifold. They had to take out the distributor and put it back in and time it. I think they made a mistake. When I take out all the plugs the engine turns over nice and smooth effortlessly, but when I put the plugs back in, it struggles to turn over as if it pushing against something off and on. Do you think that could be a timing problem?

If they didn't mark the distributor before it was removed the valve timing is off.
