calm down scooter. if its one lifter and it quits tickin when it gets warmed up dont worryabout it. i know that easier said than done but once she builds up its fine.its when it wont quit tickin that you should worry.i got a small block been tickin for yrs. also had a 225 that had a main knockin. that thing knocked for 6 yrs and i drove that truck everywhere and hard.one of the things i dont like about fordge pistons is the rattle they make when you first crank them up...
