Listen, I’m going to give you a hint. I think you are young enough to not know the history behind these discrepancies.

1997 I was 280 on the seat and by the 2001 I was 340ish on the seat and almost 900 over the nose, depending on what spring I could get, installed height etc. Some people today still lose their mind.

My point is ALL cam companies think it’s a selling point if the spring pressure is lower than another cam guys lobes need. It’s ignorant.

Like I said, there are some limits. With flat tappet cams you just can’t get that much load on them. 150ish on the seat for street/strip stuff is it. And that’s a SFT lifter. HFT lifters get pissed off over 140.

Hydraulic roller lifters can take more spring load than SFT or a HFT. But NO cam guy will say that.

My point is regardless of what the cam guy wants they always always call out too little spring load for rollers.

If you are higher than what Dave says on the seat who cares as long as you aren’t over 180?

Over the nose…400 is ok.
