Always liked the cl and cb 350's, just turned a CL down a while ago.
May be just me, but I think that diamond plate heat sheild is a lot nicer looking than some I've seen.
definately is the cb200 tank.
Not sure where you'd look for info on the pistons, with cars/trucks you can easily find the compression height, deck height, pin location etc on the engines, so if you know what you start with you can pick and choose rods, pistons and cranks to match anything you want to build, looked, but can't seem to find the same info for bikes. Bore/stroke is just a starting point.
Ford SVO used to publish tables in their cataloges with all that information for every Ford engine from 4 poppers to eights.
Since I'm not a chevy fan I don't know if they ever published the same info, but friends are into shovies and do know where to look for it
