318 LA roller block questions

Build it as a 318 like Ma Mopar intended. Gawd, if I never hear someone bring up "stroker motors" for the rest of my life it will still be too soon.
I kind of get them if you want bigger than 440, but we have 318/340/360/383/400/413/426/440 pretty much every 20 cid increment from 318 to 440. But each to their own.
