450 head on 305

[olebmw]

Is there a site that goes into detail about what is involved in installing a 450 top end on a 305?

Pete Rhodes in the UK did that trick a few years ago. It's not complicated - a little welding and drilling to move all the studs and open up the crankcase mouths.

Pistons that size tend to come with larger pin and that means a different crank & Rods or at least a crank rebuild to take different rods and that's manageable with a full machine shop.

I remember seeing that one on her or somewhere online. Lot of work, but quite the build. Also saw once, where someone put a Suzuki Top End on a CB77 as well. I Think it was a GS400 top end? Now that I would like to look back into both of those, I don't know where to find them.

Ellis Moore did the GS400 Version

Yep - you're right. I was thinking about an English guy who makes gearsets.

Les Barker of Vancouver, WA did much of the machine work to adapt the the GS400 top end to the CB cases. I remember talking with him at the time of the modifications for Ellis.
