Rebuilt engine, bent push rods?

StrokerScamp said

if it was runnin fine and then bent pushrods, that means somethin changed. did the idiots put a nylon camshaft gear on it? if the engine kicks back against itself trying to start just ONE time, it is possible to strip all the teeth off a nylon timing gear. that's the only thing I could think might have happened. SOMETHING with the camshaft timing has had to change to get these results.

Sorry, you're gonna have to explain what "kick back" means. I wouldn't be surprised if they did, as a lot of the original parts were of the mixed material type. The timing and all are still dead on, and I know the cam was replaced with an rv cam, but the shop should have adjusted everything to within a very close degree. The engine cranks, just won't fire like there's no spark; I've already verified both fuel and spark though.
