Should I run a C4 or a C5Z06 'vette in Stock?

[BlueOval Ralph]

Be careful on Z06 as it has 4 things that in production that are listed as no nos even though it has been in guide for at least 2 year! *** rods and intake valves, CNC ported heads, and dry sump! The wizards at NHRA did not even know about the CNC heads till about a year ago!

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!!
