Spring pressure for hydraulic roller cam?

I called Howards and they suggested Lifter Part # 91774 specs for those lifters are 130-180 on the seat no more than 385 open. 7000 max rpm. My springs are [email protected] seat/[email protected]. Looks like I'm good. I have no intention of winding it to 7000.

I tried going the hydraulic roller lifter route on my 493" RB. There is a delicate balancing act between having just the right spring pressure, having too much and having too little. Mopar hydraulic rollers are behind the curve compared to whats available for GM LS engines. I love those Indy EZ's. Mine flowed 345 Intake with a non-Max wedge port. I ended up going to a solid bushed axle roller, and love it.

Those cam specs don't seem optimal for a motor you are not going to rev that high. Why not consult a cam guru like Dwayne Porter?
