Need a number for Edelbrock valve springs

DueceDuster said

I have a set of Edelbrock Performer 6077 heads on my 340. I am going to a bigger cam so I need new valve springs. I looked in their catalog and come up with 5767 H as a part number but I can't find them with the H at the end. Any suggestions?

The 'H' in their listing is for footnote H, which says 'Fits #60179, #60779 & #61779'. So just go for PN 5767. You may also need the retainers and locks.... no way for us to know what is on there now.

There is more to picking springs than lift# alone, fast acting ramps(esp. those possible w/Mopar's .904 lifter)/ or rollers need much more stable springs for the same lift than smoother profiles, sooooo what does the cam mfr. tell You to run...type/& open/closed load................................

This is a good point; the Edelbrock application notes says that their springs are good for 'all Performer and RPM cams'; i.e., Edelbrock's catalog cams. Looking at their cams for the SBM, the ramps are pretty doggone slow, so these springs may indeed not be suitable for your new cam if it a fast ramp cam. These 5767 springs are a single spring with damper.

Can you share the new cam PN and brand?
