If you raise the engine, the spinner and cowl will not line up.

The model's picture shows a spinner. The cowl and spinner make a decent looking nose together. They make an ugly, out-of-line nose when they don't line up.

If the firewall is not pre-drilled for the motor mount, you'll have no problem locating the mount so that the prop shaft of the engine is centered for a straight, in-alignment cowling. If the firewall is pre-drilled, I would suggest that you study the problem of filling the holes and drilling new ones.
