Yes. Thank you. Good call. I meant valve lift which is what most people quote. Sent from my iPhone using Tapatalk

It can be confusing. Some cam specs are total lift at valve, some may be cam lift BUT that is not the end all, there is rocker ratio to consider so even if a cam card says valve lift rocker ratio could have changed.

Agree. It is valve lift. In most cases rockers are not changed but it has to be calculated if the have. Mine have to so I know that. The bottom line is that most just put them on out of the box and have no clue. Then springs, cams, or lifters are blamed for any issues.

Been reading this over past few days and now I'm hesitant on a cam ... I would like to buy a full cam kit package from a well known vendor say on the camaro5 forum (lots of good vendors with knowledge on here) wouldn't they be able to provide me with everything I need including the correct springs, seals, rods, oil pump etc.. based on what cam I chosen from them? I can do the install and then get the car to a tuner for tuning and dyno pull but I'm a bit nervous about not getting everything needed and specifically size right.

Both sets of springs in my car were shimmed to correct height. Never had a set of springs just drop in.

I've never seen a set go right on either.
