I have done about 40 miles on my new engine, and today, while taking off from the lights, the engine started running rough.On looking in the rear view mirror, the r.h. pipe was blowing heaps of smoke, and at idle the revs were up about 200.Upon getting it home i hooked up a vacuum guage and restarted it. No smoke for a couple of minutes (then plenty) but still running rough.Pulled the pass. side valve cover and no pushrod for no.4 intake. Pushrod cup broken into 3 pieces, luckily still in the rocker area.I have installed new camshaft and all new top end; valves, springs, collets, retainers; rocker shafts, 1.54 rockers and longer pushrods. i put in longerpushrods because i kept the '56 oil trays.I have no idea why the pushrod broke, there does not appear to be anything wrong, other than lash was a bit loose, i was going to re-adjust valves when i got home today.As i do not have another long pushrod, will it be ok to run one of the slightly shorter ones that came from the engine, until i can source a new one from the USA, or should i replace them all with the shorter ones (which were a bit of a mismatch of two different styles) ??Thanks, Al.
