Springs and Cam. I recently had comp 918 springs put in with my cam 232/234 595/598 112lsa what do you guys make of these springs? I thought pretty highly of them which is why I got them, but I was interested in your opinions. Thanks Ben
Let me guess, something happend??
I had them on my LT1 car, they worked fine, its just that the installed spring height had to be done because the cam was a 224/224 @ 605/605 on a 110 and it was VERY close to coil bind and you couldnt just assume.

Truthfully, I would of never used 918's with that Cam. Yes,they are rated for it but we only use them up to .580 lift. P/V is probly .100 on that Cam and a good over rev with probly eye lash the pistons.

they should be fine..... but I'd have them pressure tested after say 8 to 10 thousland miles to make sure they are still o.k. A cam like you went with they should be o.k.... but after abotu 10K I'd check the springs to make sure they are still strong enough. If ya see any getting weak, then ya know what needs to eb done, another set, same thing or a little stiffer.

If you're that worried about it then change them out sooner then later... you are running an auto so the over-rev is less of an issue then with a stick car... but if it's a piece of mind you're after then do it as soon as you can IMO.

the fact is no matter how good the spring is, if your running an aggressive spec'ed cam or the lobes ramp really quickly its going to hammer the springs, eventually even the best have to be swapped out, so for now, make a mental note to do a spring swap during the off season and depending on how close to 10-12k you are.
id be a little leary with the 918's and that lift not to mention im sure its aggressive ramp rate. even if its just peace of mind id swap them for a good dual spring . reason being if one does let go do you really wanna learn the hard way 
Ive dropped a valve on my LT1, it was comp cam 987 springs, really beefy ones, the locks cam out, luckily, the valve stayed, cost over 300 to fix, the piston got magnafluxed and was fine. I lucked out.
Either call the company that ground you the cam, looks like HPE, ask what they recommend, I assume they give you what was expected with the cam, unless you bought everything seperate.
OR call eastside and see what they think and buy the stuff through them, either way you should be able to get a good idea.
I mean the cam is in there, it works, its not dropping valves, its making power, so no need to rush and kill yourself for doing it.
