340 Vs 360
Ill give you the answer. You’d know this if you had any experience in anything other than arguing.
Five 3/8 bolts will NOT hold the shafts down under load unless you run hydraulic cams or really small SFT stuff.
It boggles my mind that you're really arguing that Five 3/8 bolts holding down a rocker shaft isn't rigid, but one single 7/16 stud threaded into an aluminium cylinder head is.
Top fuel hemis hold their rocker gear with 3/8-16 x 1.75" bolts.
Ten of them per cylinder head. Or 5 per shaft.
Five 3/8 bolts per shaft are good enough for an 11,000hp top fueler, so they're good enough for me.
You're welcome to have a preference for one individual 7/16" stud per valve spring. Go nuts.
The five 5/16 bolts on passenger car heads will barely take a .600 net lift SFT. You can see the witness marks saddles.
I‘d post a video of what happens on a BBC chevy when the bolts can’t hold the rockers but it won’t help you understand ****.
I'd rather you show me a shaft rocker system being inadequate since that is the thing on which we don't agree.
I can fully believe a bbc rocker stud would **** itself.
I know exactly how a valve spring works and you inferring that picking up an engine with four 5/16 bolts is as much stress and strain on the fasteners a rocker shaft bolts shows your limited experience and foolish ignorance.
Back on ignore.
That isn't what I was intending to communicate.
I think you know this.
The point was that multiple fasteners working together can be much more effective than larger ones working individually.
A 5/16 stud is pretty weak. But 4 of them is much stronger than a single 7/16 stud.
You wouldn't lift an engine with one 7/16" stud would you?
The whole is greater than the sum of it's parts.
Which is why a top fuel hemi can have ten 3/8" bolts successfully holding down it's rocker gear and run valve springs with 500lbs on the seat, 1500lb open pressure and making 11,000hp.
Show me any stud rocker system that can take that kind of abuse and work as intended?
Again, something tells me you'll just ignore this question and shout your opinions and continue name-calling.
I've actually been nothing but respectful and polite to you, just saying.
But when you're wrong, you seem to tantrum, and I doubt it goes unnoticed by most here.
