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.
no not as yet ,i might do it to Austin's engine.Yep ,I have a cam wife bought 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?
