If you do know can you help me out with a part number. Or just some info on them so I can contact the company. Thanks fellas. Derek

 

I run K-Motion springs in my motors (Summit KMO-K-750). I run factory lift, but I believe that they can be used up to .550.

Best bet is to just call a few companies that carry difrent mfrs, like summit or jegs and they can find what you need. Or other best bet is to call mfrs directly. But ill move this to 3rd Gen in case someone there has looked at this before already...

Also can you shorten your sig? I count 27 lines on yours and general board rules is around 5 lines... Thanks Derek.

All the folks who really know their business will tell you to go from 1.25" to the 1.4x" diameter springs when you get that much lift. To do so will require having the spring seats on the heads machined to that larger diameter, as well, to accomodate them.

Good luck, eh?

 

Scoggin Dickey sells some "Heavy Duty Z28" springs they advertise as being good to .550" lift. I believe these are the same springs they run on their modified Vortec heads which they also rate to .550"...

Not sure I'd really trust any 1.25 spring to that much lift though, but that's what they rate them at FWIW...
