426 inch+ small blocks

well, I am....

The crank which is 4.125" is from last year, which is a newer design then the LS series engine I am referring to.

about the only 40 year old technology is the block's dimensions - and guess what? The block does not know what year it is!


I was referring to compression height of the pistons and the ability to live long term, and I still stand by the fact that if an LS series engine can have a short CH , then so can ANY motor, regardless of what year the block was originally cast.
