Hi friends! I bought the performance camshaft kit with cam lift .480 and duration 274. My questions now are:

What are your experiances (if you have installed the kit) and - in special - how did you go on with the valve springs. My mechanic thinks that the valve springs are too strong (130 kp) for that camshaft compared to the 80 kp of the stock springs in my ' 72 240 Z , that might be too weak for that still quite moderate cam. Thanks for your support

Been running that set-up for about 15K miles and the cam looks great-EXCEPT for the lash pads. Have the rockers checked(if came with the kit) for flatness or the surfaces being parallel. I have had odd wear because of this issue. Doesn't seem that spring pressure has hurt anything though I have read that it is high relative to stock nissan or other cams. I dynoed 155RWHP with my L24 with this cam. Great low end and pulls hard all the way to 7K

Hi Steve,

thank you for your reply, that is encouraging! Can you explain a bit more what happened to the lash pads and how you solved the problem, please
