Edelbrock step-up springs

[crackedback]

Anybody have a set of blue and yellow springs I could borrow or buy?

I'm tuning on a 340 with a large cam and an 800 thunder, has orange step ups in it an the pistons move like it's running with the engine. Need some lighter springs so the rods stay down at idle.

Thanks
