5.2/5.9 H.P build guesstimate
Here's a 5.9l magnum going from stock 200° ish to 212° cam.
If we guesstimate torque to 2500 rpm, if you minus the little tick up as the dyno kicks in, looks like stock curve probably will start around 380 tq and the 212° around 370 tq.
We can guesstimate a 218° and 222° and 230° cam curve.
Above 3500 rpm each should be basically all gain each step you go up.
From 2500-3500 rpm is the question how it's gonna be, If you look at the 5.9l crate it makes 381-415 tq and 181-277 hp 2500-3500 rpm so bigger cam doesn't automatically mean bottom end will be destroyed. So stock is basically making the same as the crate at 2500 rpm plus the crate is a single plane intake.
Say the 230° makes the lowest at 2500 a 218 probably be similar down low as the 212° and 222° maybe some where in between.
You have a 3000 rpm stall so 2500-3000 rpm ain't overly gonna matter much above 3500 rpm these cams should be all/mostly gain each step up. So 3000-3500 rpm might be questionable but bet there at worst making somewhat similar power there.
So really smaller is more for idle, maybe some gas mileage, maybe better under 2500 rpm cruising etc.
