Hope this helps...
My 428, when it made the finals, only lost two races. One was to a 500 cubic inch chevy, and the other race was to a 426 Hemi. Both beat me by less than 48 inches at the finish line. At this proximity, it is launch quality and reaction time that determines the winner. I ate a fine cuisine of short rod big blocks in my time, and they came up wanting..... Even the 427 Fords couldn't hang with me in my bracket. (short stroke, short rod, huge pistons, this design is called "over square". It does very well on track courses where the rpm capabilities of the 427 allowed it to dominate until the 428 and then the 429 replaced it.
The 428 was a little bit of magic with its 1.88 to 1 stock rod to stroke ratio. There are very few engines before or since with these types of ratios.
Building a 10 second car is getting relatively easy. Like I said in different thread, it is getting to be like building with lego blocks.
