i need some advice on rod lengths and piston compression .i'm building a 4.150 stroker 440 based mopar. the deck on the block is real tall (10.720) the option that i have are 6.800 or 7.100 chevy rod length. which was is the wiser choice? shorter rod and tall piston or long rod with less compression heigth. the engine is for drag racing, thanks

my opinon would be to use as long a rod as you can to get a good rod ratio so the motor lasts longer and also i like to stay away from very low compression height so i dont have to use the aluminum buttons for the rings.
