Hello,

I came across this good article on Valve springs for mopars, I noticed its been taking down now and all the info gone, I have a copy of it here in PDF if anyone is interested. Below is what I found most interesting about the magnum engines

RECOMMENDATIONS

Keeping all these items in mind, the HP spring for the big block engines (383 & 440) and for the 426 HEMI Gen II engine is P3690933 (used in production on the 426 HEMI engine and 440-6BBL). It is good for cams with up to .500″ valve lift. The HP Magnum and 4.0L Jeep vehicle in-line six-cylinder spring is P5249464, and is good for .525″ – use P4876062 for lifts up to .600″ (both use retainer P4452032).

I thought it was rather good how you could get .600" lift with using the right combination of parts, .600" should see most street cars covered with a big cam.

Now it's archived here and can't disappear from the web.


Thanks
Bruce
