Got the truck back today with my rebuilt 235--purrs like a kitten. This has Fenton headers and 32/35 Weber from Langdon's stovebolt, Was bored .040 over and new Rockers and rocker shafts. May go for a long drive Sunday, as we have no snow. Do I follow the 49 Op Manual and drive no more than 35 MPH for the 1st 100, 45MPH for the next 200 and 50 MPH for the last 200-then change oil? Thanks for your input...Bill
