Hi, just wondering if anyone has ran a 4K spring kit and what your experiences with it are, what are the vibes like whats the power like. I appreciate you need the 60lb valve springs.

I have them in my truck ,I installed them when I changed the cam when the conversion was done back in late 2000.
The springs I didn't change them they say you need to but for the few times I have it close to that high of rpm I run out of gear and boost for my turbo WH1C (37 psi ).
I don't plan on changing them unless I do more upgrades to the engine.The engine runs just like it does @ 2000 rpm I can't tell the difference.If I was to run at the higher end of the rpm than I would change them .

Ask tndonor he loves the truck and the power it has and always ask now what be done your engine everytime he rides in it.

Thanks for the reply Scott, have you ever had any experience of one in a 4BT? or anyone else had experience. I will definitely be doing my 6bt but wondering about 4BTs and how well the 4 banger revs to 4K. Scott don't you have a nice cam in your 6BT?

If you could see the shop she's letting him build at the house you'd be asking if she has any unmarried sisters..
