opinions on a 340 build

Block is standard bore. Still sonic check?

I just had a Stroker built out of a 72' 340 and my block was standard bore, they went .03 over and I don't think they did a sonic on it. I think as long as you aren't going .6 over you should be fine IMHO.

Cheers and good luck. I love strokers!
