8.2 is the deck width of the block . 9.5 is the deck width of a 351 hence why you'd need a new manifold if you went 351 either way.How bout dem Giants
You confused me when you said touching on the big bore subject. I get that you said a big bore Dart is 4.125 and stock is 4.00. I'm assuming you mean a stock 351 or do you mean a Dart stock or Dart 8.2 ( Dart stock and Dart 8.2 is the same?)
Stock 351 and 302 bore is 4.000 if I remember correctly . You can get a dart shp with that that bore size or in a 4.125 big bore which is what I have and that's how you'd get to the 363 .
And I am most deff a giants fan
