Need help asap 340

depends who rebuilt it....if YOU rebuilt it, take the 10 grand and send the engine to a reputable builder and have them do a stroker.....if it WASN'T you, then find a different builder (or do it yourself if you know more than the builder)....if it was rebuilt just 200 miles ago and you have pushrods coming thru = somebody messed up and they shouldn't be allowed near an engine....
