When I bought the truck it had some minor smoke from the tailpipe at idle. The previous owner said he had no idea how many miles were on the motor so I had David's Engine Shop, here in East TN, build a four bolt main 355 with an Erson Roller cam and Speed Pro pistons. We used a one piece main block that he had and once the rotating assembly was ready and in the block, I pulled my engine, took it to him and we used these center bolt heads on the new four bolt long block. We used roller tip rockers, a Cloyes Double Roller timing chain and completely reworked the heads. The engine bay was fairly clean. The truck was only showing a little over a hundred thousand miles.
