Wow Brent, now your a mind reader. You need to put that on your business card, too.
Frank, I just figured out what you're doing and it's very cunning. If you hang around long enough and start enough arguments with engine builders, you'll figure out which parts to use on your SBF build. That's a good way to look knowledgeable and save face! Kudos to you! So far, we've helped you with pushrod diameter, valve spring pressure requirements, and that Erector Set main girdle that you built. You're well on your way now!
Frank: "You need to save weight on pushrods."
Engine builders: "No, you need to use the largest diameter, most rigid, pushrod that you can fit."
Argument ensues. *Frank furiously taking notes, "Small pushrod bad. Big pushrod good."*
Rather than make up what I say, I'd rather that you find the post and do direct quotes. Is that asking to much?
Regarding the push rod topic, what I actually said, had nothing to do with the size of the push rod. I asked, why run the oil threw the push rod, like you do with your rockers, since it adds weight, rather than use the std oil system, with dry push rods. I don't know why that upsets you?
Frank: "Seat pressure isn't critical."
Engine builders: "Seat pressure is arguably more critical than open."
Argument ensues. *Frank writing: "Ok, seat pressure IS important."
Again, what I actually said, was that I want the lifter and lobe, to remain in contact, with ~.060 CBC, FIRST, take what you get with seat pressure and if that has to be addressed, use the heal, to address it.
I get it now! You're such a sly one, Frank.
Again your mind reading skills kick in )
Since you apparently only have access to a 1969 TRW parts book, just let me know if you need any help picking valve springs and components for your build. I have access to a lot of stuff and a lot of technology has changed since you built that 427 50 years ago.
At 7K the valve train, had no issues, with the SL, Chet Herbert Roller cam. He directed me to the right springs, rather than suggesting .600 springs, for a .670 cam as I saw done last May. Math skills again?

Wow, you win, Frank. You called me out on a post where I got part numbers mixed up, was corrected on it, and then I apologized. I guess that was a crime against humanity that just can't be forgiven. BTW, that has nothing to do with the discussion we're having on valve springs, coil bind clearance, or remotely anything of the like, but I guess you gotta get your jabs where you can, right?
And just so you know I'm not making anything up, here's a direct quote, straight from your keyboard, in response to a post that I made on April 6th of this year stating that pushrod weight has no bearing on the springs/valves/etc...:
"If this is true, then the weight of the lifter, means nothing also and why do you use aluminum rockers?
I was taught that the weight of everything in the valve train means something and that lighter, w/o failure, increases rpm, given the same spring pressure. Am I wrong there, too?"
On April 11th, following that post, since you didn't believe us here on the weight of pushrods/lifters affecting rpm levels, you posted on Speed Talk and asked this question: "How much does the weight on the lifter/push side of the valve train effect increasing the rpm potential?" You were schooled there as well.
My point is, Frank, you would be much better off, when faced with something that goes against your "understanding", if you would just approach it with a larger degree of tact and open-mindedness, considering a lot of what you know is extremely outdated.
By the way, I know you're wanting to get one last jab in, but I don't ignore lift loft either. I choose springs correctly, based on seat pressure, open pressure, lift, and whatever other voodoo you want to consider mixed in there. Have you ever had to design a camshaft that lofts the valves on purpose? I have.
Good luck, Franky boy.
