Just wondein if i could possibly take the belt pullys off and drill a cupple holes in them. Bad idea or good idea?

 

and or make some of my own seeing as how my dads does stuff like that for a living

 

Drill holes in them for what?

 

your not going to gain much at all...its not like a SBC or a BBC. Pointless i say...

 

Light weights

 

You might as well just remove the tire iron from the truck- it weighs 50x more than you're be able to remove from the pulleys. Also, it would probably negatively affect belt life.

Shave a little off the fly wheel if you want less rotating mass in the engine.
