305 to 350 or 305 to 305 SC?
Ok, over this winter im seriously considering a supercharger for the 305, or upgrading my block to a 350.. Any thoughts on what to do? I would really like to do a project over the winter, and bring the Z out in spring and shock a bunch of people i would see crusin' during the summer 
Also my friends and i would all work on gettin this done, so time and man power really isn't too big of a problem
I'm also wondering on advantages/disadvantages for cost VS time to install?

...what about both? 
Well, the 350 wouldn't be hard to swap at all! The only thing you'd have to do is get a chip for a 350 for it to run. You could build a sweet 350 and dump it in with a good cam and heads and then go ahead and get a big mouth manifold and better runners, etc.
Or you could supercharge the 305. My buddy has an ATI 9psi kit on his 91 Z28 305. He made 384tq and 350-something hp before he sorted out his fuel system problems. His car is NOTICABLY faster now with new lines and a different FMU setup.
But wouldn't it be neat to take a 350, re-ring it, put some better rods and some forged pistons on it and then get a supercharger? If you want, toss in a different cam that would work better with the blower and go to town. You'd have a solid 350 that wold probably make some good power on it's own AND it'd be blown so you'd be making tons of power.
At that point I'm hoping you don't have a T5 because just the stock 350 will tear it apart after a while.
