which one supertech spirings i must use with 10k rpm and pro1 cams?
70 or 85lbs of seat presure?
i know taht pro1 cams doesn't like high seat presure, but 10k rpm tels me something diferent, so what do you guyes recomend?

 

I would also like to know this. I currently have the 85lb springs because i got it for 50$ brand new but If its too much then i'll sell it and get the weaker one.

 

??

 

i have this exact deal, i used the 85 pound springs, they are the "hi lift" springs

 

In for a response, I have 70 lbs springs.

 

If you honestly think you will make power up to 10k, the 85lb springs are what you are looking for.

I only rev out to 8600 on the 70 lb springs with CTR cams, so I don't have any experience with the stiffer springs.
