Difference between 360,340 and 318

I don't know about easier but short stroke = quicker revs.

It revs quicker in neutral, but how about with a load on it?

They don't award trophies for how quickly an engine will rev in neutral....

A 360 has more torque than a similar-build 340, and will excel at accellerating X number of pounds due to the longer stroke and having more cubic inches.

You'll notice, I said "similar build." Race 340s with W-9 heads and 14-1 compression are apples-oranges compared to a street 360.
