I will stick my toe in this pool very carefully.......I for one do not consider any 351 based engine a Small block, I am sure I am not alone on this. A small block is an 8.2" deck height block, then take all the liberties with the internals. I think that taking an OEM Ford 351 Windsor to extremes with paper thin walls and enormous strokes thus increases the piston speed to the point that you will be reducing the longevity significantly, and that is without even mentioning the 3" main bearings. It can be done yes, and you do have 427 Cubic inches but at what "Price"?
If you want to grow, and make big HP take a lesson from the "Winston" Cup Boys. 358 CU IN. In a big bore short stroke aftermarket block, Yates type Canted Valve heads, stout block and crank, RPM it to 8500 + all day long and and have far superior throttle response to any true Big Block.
