Okay I am looking to purchase either a 421 cub or 421 serval. My understanding is cub has high end power mostly for dragging, and the serval port timing makes a more useable power curve mid to low, for duning. Here is my question if I dune port a 421 cub am I lowering the power curve making it similar to a serval? And if I dune port a serval what am I gaining there? I am trying to figure which to purchase I just don't want to buy a cub and port it if the end result I am creating is closer to a serval, just I spent more money to make it. If someone could please help me better understand what I would be getting with the dune port work on each top end I would greatly appreciate it.
Personally I mostly ride the dunes and bowls but I do like to hill shoot so I'm trying to figure which way to go on these motors to fit my style of riding. Thanks in advance for your responses to help me understand the differences.
