fm14 and patriot golds
fm14 and patriot golds ordered my fm14 and now trying to decide on springs. i want to put dual springs for sure but wasn't sure about patriot gold .650max lift spring.will a spring with more max lift last longer than a spring with almost the same max lift as the cam. in regards to shimming this spring for proper seat pressure. does it need to be shimmed or will dropping them in work fine...2nd what/how do i now what size shim to order/ put in..lift on that cam is .598/.598..any comments/help is appreciated...thanks
I talk to Patriot and I'm putting in a Crane 250/266-650/650-112 +5 in my new LS2 418 cid. Still under construction and they told me that there Duel Gold spring would be just fine with that cam and safe just make shore there installed at the right height 1.8" .I have them in me 348cid. with the T-REX 243/249-609/614-109 with no problems and cranked the motor up to 7800 rpm and still running strong for over two years now.

yeah i would go with a spring with .650 max lift, cuz i wouldn't want something at or near the max lift of my cam ie. .600, you don't want to be practically maxing out your springs everytime you start the car.....i would leave yourself some wiggle room but thats just my.02.
