318's thicker ?

Sorree Dudes, I thought it was an honest question, do 318's have thicker cylinder walls because of their std.3.9" bores, instead of 4"/4.04" ? True story, Dodge Dakota V6, 5.7-6.2L hemi, and our "A" motors, all have same bell housing bolt pattern. Since "certain" years of V6, stick Dakotas used asian warner trans, also direct fits the Turbo Supra 5 spd,(stong trans with good ratios).Easy to peep this layout ,on British V8 forum, eng./trans section. "No chirp", as in don't get sick over my build. LOL's all around, Art.
