Is it safe to rev 9k+ with drop in pistons and rods with a 2.0? Also from what ive heard a drop in setup is good for 650 whp. If that was done on a dyno dynamics dyno, would that be a safe power level with a 1.00 setting?

 

upgraded rod bolts?

what are your valvetrain specs?

if you aren't running upgraded springs and retainers then it's not safe

 

Need to upgrade the valvetrain before revving that high.

 

The head is built too. I dont remeber the specs exactly, I did not build it, but I do know it is built to withstand 9k+ rpms.

 

What about powerwise?
