408 hyd roller, too much spring pressure?

I’m saying go back and look through a bunch of threads where BH springs are talked about. You’ll see the same guys telling people who have springs hitting retainers to just drop a set of BH’s on there and send it.

That’s a bullshit thing to do, because 99.999% of the time they hit because the geometry is wrong. The correct fix is to unscrew the geometry, not to change the spring.

Of course, the dudes that always say to use a BH spring never say to fix the problem. They just tell people to cobble their **** up.

Do a search. You’ll find it for yourself.

Want to use a BH spring? I couldn’t care less. But you don’t use one to cobble something together.

Plus, their performance is grossly overrated. I know they don’t like RPM. I’ve broken enough to know that 8k is their limit with an OHC and Ti valve.

You asked if I bothered to read this thread – not the entire forum! :eek:

And what do you expect me to find? Racers breaking beehive springs at 9000rpm or whatever? Is 8000+rpm a realistic goal for the average street-driven musclecar? Because if you are focussing purely on the hard-core racing community, you are missing the much bigger picture of all those people on the street trying to build what they can within their budgets to suit their daily or weekly driving habits with maybe a few squirts down the track each year.

Again, with respect, we are not all full-time (or even part-time) racers.

And just like 99.999% of us are NOT full-time racers with unlimited budgets for exotic titanium valve gear (or whatever), I wouldn't be bold enough to say that 99.999% of the time the issue of retainer to rocker clearance is rocker geometry, as there are always exceptions. I had one myself a few months ago where my machining instructions weren't listened to and I was forced to go to +0.050" locks because the only other alternative was to machine the spring pockets on an iron head to use the springs that I had matched to a custom cam.

There are many ways to skin a cat.
