I'd go with the .890 383/440 bars, 1" or step up to .920 bars. I intended to build just a mild 360. It has turned into a race prepped 414 stroker, ported heads, portmatched intake, 1350 U-joints, chromoly driveline, etc. I say go ahead and step up now because you won't keep that 318 for long. They are about the same price!
