Nothing is a given. The 71 blocks seem to have the aura of being thicker. But core shift tends to make that a myth. If you plan to go 4" stroke, have it sonic tested. Look for a minimum of .150" (or whatever your builder likes to see) on the major thrust and go from there. I dont like to do strokers bored further than .030 unless the block tests perfect. For stock stroke, I think .040 is the max recommended overbore. Again, sonic test to be sure if you want more.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
