Do you have to do any clearance work to get a 8 inch crank in a g?

Depends on the journal diameter. And if using a stock rod or an aftermarket offset cap rod with cap screw style bolts.
Should be able to go more than 8" with the offset cap rods and an A sized rod bearing.

If using an A or G rod you will also have to notch the cam.

I've seen 8.25" with A rods. A little clearance and the back and a little to the camshaft.

Next year, you'll be asking what it takes to put a 9.25" or 10" in, and if your +0.125" MW pistons will work. The answer to those questions is, 9.25", not bad, 10" quite a bit, and no, your old pistons won't work.
