4K GSK without 60 lbs springs?
 

Ok,so i just my injectors and 4k gsk but my valve springs didn't come in the mail,So im wondering if its safe to run the gsk without the valve springs?:humm:

As long as you don't rev any higher that 3k you will be just fine.

Wow!Its that high?Is it hard to tap 3k with these springs?And can I toss her to 4k when i get the valve springs?:tu:

If you have the fuel, and with injectors you should, hitting 3K with a 4K kit is no problem. Much higher than 3K will take some doing though, it depends on your pump tune/setup. As long as you keep an eye on the tach when you're standing on it and don't let it get out of hand (which should be very easy) you won't have any issues running it without valve springs. By all means get them in ASAP so you can make the most of the kit, but it's not going to grenade unless you're being stupid with it.
