Which would be a better Stick-Shift Stocker, a C4 Corvette or a C5 Z06?

I like the C4, and it seems as though it would be fairly straight forward to build, but I like the C5 more (quicker, better looking, etc.). However, making the transaxle in the Z06 work has me concerned, as in, should I go with a solid axle or keep the IRS, is there a manual tranny that will work back there, etc.

Also, with the factory rating on the Z06 motor already at 405, is there much more that can be rung out of it compared to the LT4 in the C4?

Any input is greatly appreciated!!

The C5 Z06 LS6 is overated at 405 hp, the LS1 in the C5 with a slightly smaller port/slightly less compression is rated at 340 hp, a much better combo I think, and can run B/S thru E/S depending on which year is claimed.
