"The difference between a 350 and a 327 is the bore and stroke. A 327 has a small bore and a short stroke."

Not quite right. The 350 and the 327 both have a 4.000" bore. The 350 stroke is 3.480" while the 327 is 3.250".

" Strokers have longer con rods which equals longer strokes. 305's and 350's are same block I know but that's about it."

Not quite right. Strokers don't necessarily have longer rods, although most builders will opt for a longer rod to improve the rod length-to-stroke ratio. 305 and 350 blocks are pretty much the same externally, but the 305 uses a 3.736" bore, while the 350 uses a 4.000" bore.

Good explanation Don.
