Richard,
No. But then I think I may have added a small block to the very end of the fuselage since I chose to close it in. I typically leave room for the fuel lines to come through the center of the mount and around the engine.I would not be able to do that if I installed the engine as far back on the mount as it would go. The end point for the nose is somewhat adjustable. Make it longer, add a block. Make shorter, saw it off. Easy!

PS- Now that I think about it the fuselage nose is one of the few places where creative adjustments can be made without drasticallyaltering the overall scheme of things.

PPS- Theoretically, as you move the engine forward you could reduce the diameter of the spinner say 1/4" and get a sleaker/ slipprier front profile, as well asmoving the CG forward to offset any extra tail feather weight. Just a thought.
