GT/AA Class War At Indy

[Alan Roehrich]

The minimum in Stock for a 427 is around 1.735". Now, assuming a stroke of 3.799" and a rod length of 6.135" to remain legal, you're talking about taking 0.535" off of the block to get to 1.200" compression height. At a compression height of 1.735", you're already 0.030" below blueprint deck height which is 9.800. So to get to 1.200" compression height you'd need to get down to a deck height of 9.235", and I'm not sure you can take 0.565" off of a Bow Tie block and keep head gaskets on it. Besides, if you took that much off of it, there'd be no top bolt hole for the water pump, because at 9.800" blueprint height it's probably not 0.375" below the deck. I've seen some of the fastest SS big block Chevy engines in the country, they don't LOOK that heavily altered, and USUALLY I'd see that, there'd be some REAL obvious clues, like the intake touching the timing cover. But maybe I'm blind, or just over looking it.
