What advantages are there to a 6" rod in a 350 Chevy?

i think we've been over this before but..... a longer rod creates more dwell time at TDC and decreases the rod angle. more dwell time allows more time for cylinder filling and makes cam timing less critical. the decreased rod angle gives the piston more leverage on the crankshaft and decreases cylinder wear.

it's a win-win situation. a long rod engine will outperform a short rod engine of the same design every time, in my opinion...

The most that a 6" rod can help, as compaired to a 5.7" is 2%. This number was told to me by a man who ran dynos for a large parts manufacture/supplier, who doesnt want the name published.
