My brother and i areworking on restoring a '56 chevy. This is our first restoration project. We're thinking about boring out the stock 265 engine. It still purrs like a kitten, but we need some more horsepower. What i need to know is:
A. What is the largest we can bore the 265.
B. is it really worth the trouble. We've already decided to dumb the 2 spe3ed powerglide tranny for something with an overdrive. Any suggestions on that would be much appreciated as well.

Also , if there's anyone in southern california who knows a good nickel plater, and if that's worth it.
