Howdy all. I am curious as to what experience any of you have had with holley secondary spring choices. I have a 292 bored .030 with mummerty aluminum intake and headers, and isky e4 cam 9 the milder one ). I have a summit 600 cfm carb. I bought the quick change secondary spring housing and am beginning to play with spring options. Would my set up like a softer or stiffer spring? I have the white ( softest spring ) in now and it feels pretty good. Secondaries are for sure opening. I'm curious what experience you guys have had with a similar engine set up. Thanks
