to beat a GM 602 crate

I do run against the 602 crate. I have about 1500$ into my motor. 30 over 360 sp405 piston stock 360 heads hydrolic cam accelerator intake Rochester 2 bbl.
But they actually tech us and the rest have to run the same. I looked at the ump rules and you can run either the crate or an open motor with a bunch of weight penalties. to me that says the only tech will be external. It seems to me that if you were to win a lot with a non crate they would just keep pileing more weight on you until you weren't winning.
