do i need springs valves retainers and all the other stuff in the head if i run 272 cams?but do not plan on reving past 7000rpm anyway. if so why and whats needed. thanks

 

no

 

no need for that i have 272's and have stock vavle springs and retainers

 

so in not needed unless you plan on reving 7000rpm and up. what do you rev to now with JUST cams. thanks

 

Evo can rev to 7500 stock without hitting the rev limit. I did that yesterday at the track...haha.

Here is a good deal on some brandnew 272's https://www.evolutionm.net/forums/sh...d.php?t=144431

 

One important note: If you don't run past 7000rpms, then you're not even making good use of the 272s! They really shine on the higher end.

 

It is said the stock valvetrain is strong especially since you're not hitting higher rpm's. If you want to go pass 7500 I would recommend it but you shouldn't have no problems

 

bought mine here

Havent installed them yet but I ordered cam gears too, thats it. I dont even think you have to have cam gears though, I just wanted to get them to use full advantage of tuning the beast

 

So would it be ok to run 8000 RPM on stock Bottom end and fully built head from Buschur with 264's cams??? Or do i need any other changes?


Thanks

 

you dont really need em but there a good piece of mind.. and dont rev to 8000, unless you have some work done to the motor.. floating a lifter isnt fun...

 

Thats exactly what i want to know what work needs to be done to rev it up safely to 8000RPM.

 

I have Revolver springs and retainers with rev limit set at 8100... however, you really need to think about rod bolts when attempting to spin it that high. Of course you need a turbo that can support power in that rev range which the OE does not.

 

what kind of work is involved in installing springs and retainers could that be a diy? same Q for head studs and bolts i saw the right up in how-to section but some disagreed

 

Let's just say that springs and retainers are too much a pain in the *** for me to offer it as a service... Maybe I will invest in a better spring compressor than Snap-On's universal one some day.
