How does cid make power?

The difference between stroking the 318 vs the 340 vs the 360 is only bore size. The bigger bore has more potential to make more HP. Because of the smaller bore size of the 360 and smaller yet 318, the 340 block has the best HP and torque production ability. Just the reverse for less power.

Cost aside and we will pretend all parts are not only free but on a shelf that your standing in front of.

We have a 350, 361, 383 & a 400 inch low deck set of blocks. Build each one how ever you want it but all the blocks will use the same parts from stroked block to stroked block. Which one is making the best HP and Tq.?

You answered my question greatly thank you, but I think I left out part of my question that’s the most important. Most of the time when people are building an engine, it usually needs bored do to normal wear. Or sometimes it needs bored for the stroker kit. So if we’re boring the engine and changing the stroke on a small block, I’ll just stick to small blocks because they have the same deck hight. Does it matter what you start with? I think is the real question this thread is about.
