what springs are you running with the Mopar 528 cam?

Just curious what everyone is running. I'm wishing I could find a spring under the 1.44 diameter that'll handle that cam. Not really wanting to pull the heads and cut on the valve pockets. I'm not even sure I've got room to make that much of a cut on the EQ heads.

You should go with what the camshaft maker says

The recommended spring, P5249847, 1.68 - 1.70 installed height, a single spring with damper @ 1.5 diameter, 2.07 thick wire of chrome silicon .480 - .535 lift range.

Those are the spec listed. Now you can do a cross ref on other brands. I did not see a rate in the catolog. They do provide rates in the engine book which I do not have on hand right now.

He's got EQ Magnums. I'd look for a beehive for them. They don't need a ton of spring, and once lash and angles are taken into account the cam will only go about .525 lift with 1.6s It shouldn't be too hard to come up with something that will go with no cutting. Possibly the Hughes 1111?

Appreciate all the suggestions so far guys.
