Hey guys curious to see what you all have reved your stock valvetrain to? And if you had cams while doing it post the type.

Keep it under 8k on stock cams and you'll be fine

 

Im guessing your wanting to run evo 8 valve train in your talon? Hard question to answer cuz all the different makes and sizes of cams, then theres how many miles are on the valve train.

So to give my opinion, Id keep it un 7.5, can you see 8k plus, yes, but prolly not the best idea. My tuner runs comp 280's on his stock evo 8 head @ 45k miles on it. Only revs to 7.5

 

Reved mine to 8500rpm with my stock valvetrain and HKS 272 cams, which have similar lift to stock. I replaced my spring and retainers at about 80k miles or so with brian crowers. Now I keep it to around 8600rpm max and no issues so far. I even accidentally overreved to 10.5k for a split second and got lucky with no breakage.

 

I would not rev past 8,500 with a mild cam and wouldn't go past 8,00 with a aggressive cam like gsc2 or kelfords it' possible to float the valves and have valve flutter.I would just upgrade them and have a clear mind..

 

i had buddyclub 272's on my stock motor and revved past 8500 continously. they lasted for 2 years, but then got weak and i started to get valve float.

 

Yes I will be running them in my talon, probably keep it around 7500-8000 for this year then upgrade to some kiggly springs over next winter.
Thanks for the info guys. Still interested in see how high some of you are taking your stock valvetrain though.
