I read some rules at one of the tracks we go to that it's legal to deck the block, but not legal to run a 6.0 rod in a 350......both accomplish the same result, right? So why make one method illegal?

If you can't work em in close & git em in your face with their orange landing gear down, don't bother taking the safety off......

Most decks are at 9.025. A 6" rod doesn't increase stroke so the piston ends up at .275 outa of the hole. Unless you buy pistons for them that move the pin center up and compensate for the extra .300 rod lenght.

Decking brings the deck closer the the piston for a increase in compression.

Not quite the same thing.

Thanks, the way a guy described to me was that both ways moved your piston higher taking up close to a .30 gap that is from the top of the piston to the top of the cylinder.......thanks for clearing that up.

The 6" rod deal makes more power, and better use of a camshaft. The rod ratio is alot better.

There are a lot of variables to making power other than rod ratio's. Cams are ground for the COMBO of heads, intake blah blah blah. Not based around a known ratio.
