Valve springs???
i got a question i hope someone with more experience can help when i ride a gear out to about 5200 it falls on its face. almost like the valves are floating im not sure what else could cause this? could the springs be beat? or is that the normal rpm range?
motors got hedman shortys, fowmaster 40's and catless H pipe, je pistons, 1.7 rockers, bbk cold air, ford 70mm throttle body+egr plate and 3.73's I didnt do the rockers or pistons i bought it like that.

The average hydraulic roller valve train starts to float at around 5800 or so. Sooner if they're not adjusted correctly.
The big question is what cam do you have? Many cams start to give up around 5500 or so.
You can learn a lot with a little dyno time.

1. the whole hydro lifter set up can only go to 5800 is bs. simple case in point, my 5.0(now sold) had a hydraulic cam, stock lifter, upgraded springs/locks/retainers, and a good sized cam in it and would run strong to every bit of 6500. at the machine shop we built plenty of sbf's, and sbc's that would pull to 6000/7000 all day long, with hydraulic lifters. and if u want to push it even further, honda's have hydraulic valve trains and rev to what 9k??
my guess is a few things, 1. its a stock cam and stock springs. which yes the springs are prolly warn out. or its cammed up with stock springs, which in this case, the springs are dead now.
