? about using LS6 cam for turbo LQ4 can anyone tell me what valve springs i should use, and also what length pushrods i need.?
i understand i can use LS6 valvesprings but didnt know if i should use something a little stiffer to help control the valves with all of the boost/backpressure...? or is this nonsense? lol
thanks in advance

Some people get away with using the ls6 springs, but for piece of mind I'd get a decent dual spring like the patriots. Stock length pushrods will work f fine, but I believe a slightly different size is best for that cam. Don't remember off the top of my head.

you guys otta look at the ls6 cam this way as far as rpm peak, if you're shifting at 6500 and the cam is peaking tq at say 5800, well that'd be saving someone's *** in the detonation dept cuz detonation happens at peak tq, so if you're revving on past that point, than you're pushing away the chance of detonatiing the engine. point is dont cam for peak tq at your peak rpm, if you do, better run the best fuel you can get your hands on.

just get the patriot gold spring kit,
comes with titanium retainers, valve seals and duel springs for around $255
60lb injectors will do fine, I'm at 700rwhp at 85% duty cycle.
but if your thinking E85 in the future, go the 80s now.

If you are going to run very high boost, I'd go ahead and get a dual spring. If it's only moderate boost I would run the PAC1218 or 1518. Give us a call and we will give you a good deal on both some springs and the 7.425 pushrods.

I chose a TR224-.581/.581-114 over the Ls6 cam just to get a little more outa the setup and keep great drivebility.
For springs, i have patriot gold duals. Having slightly overkill springs is just cheap insurence in my eyes.
