What would be a reasonable bump in RPM?

 

Your engine should be good up to 7500 with the oil pump being the limiting factor. Your pulley sizing for the vortech will be the next determining factor.

 

Oil pump for sure ... look into the nismo or look up Jeremiah/TotalD, sucker punch motors sports, he fabs up OEM pumps with upgraded internals...

 

I have been looking into the suckerpunch billet one.

How much can the revup pump handle?

 

Cams are the Limiting Factor, way below Oil Pump

 

I am setting it at 7200. is that safe enough on the cams and pump?

What Cams and Springs?

 

Factory

 

Why not set it at or just after the power band?

Find your dyno sheet and set it accordingly.

 

Im bullt with factory heads like you and rev my DE motor to 7.2K rpm.

I have a flat poor curve from 6k-7.2k rpm but motor has been fine spinning to this on track for a good while.
