I have a 454 block, 402 crank, rods, and oval port heads, and 30 over 427 pistons with my 100 cc heads should be at about 9:8 to 1. I had the heads flowed on the intake side with bigger valves and port matched the intake. Balanced the assembly. It has a wild cam but it has sat in the garage for ten years. I want to install an rv cam and put it in my 4x4 plow truck. It was only turned over every couple of years. Will I need to dismantle the engine and hone the cylinders over again or can I liberally oil the cyls. and turn it over with a starter and run it? Your input would be appreciated.
