@Dale Davies
Since your quoting me….
Paragraphs are an excellent idea. ;)
Why? Making use of an LA cam in a Magnum is an upgrade in .1 already which should have you seriously reconsidering the exact cam specs being used. Going to a 1.7 rocker further exaggerates the issue.
To bring in one more item, the total lift of what ever the value may be, at what point does the head stop or stall at flowing air?
This is not exactly true depending on the valve lift.
Any cam change should have fresh new springs to match what’s the valve is lifted at.
Absolutely, LS not being absolute. OAL valve length should be considered carefully.
Dumb move using used valve springs. New ones are cheap and fresh OOTB
And your mentioning used valve springs, retainers, locks and valves from a junkyard?
A worthy investment for their accurate ratio over LA rockers.
Has anyone tested Magnum rockers?
How much power is the rocker worth even at the same ratio?
How much power is the added ratio?
Isn’t it easier to get a cam ground at the desired lift rather than exploit it via a rocker ratio?
A Cam intensity is increased with a change in rocker ratio. Is there not a lobe available to match or exceed a rocker change?
At what point is the valve opening speed to much or of no more benefit?
What size are Magnum valves stems?
Why do LS valves wear less and again you’re buying cheap used parts over fresh springs retainers and locks? Saving money at what other expense?
Reshaping the port floor is a bad idea? No laying it back?
A quite from his second post FWIW
As I stated above, the post suggestions will do the trick.
Zero need for anything above.
Thanks
