In Car Valve Spring Tester

Cam...you can easily remove the springs with that tester and check them with a bench tester. I have only used the Moroso on car spring tester in the past and it is not even close to being accurate. We used it as a way to look for very obvioulsy weak springs or maybe a broken inner on roller cam springs. I know the LSM stuff is very good but it's going to be very difficult to use something on the springs under the cowl of any late model LT-1 Stocker. I was doing a leakdown test on my engine and looking over the valvetrain one day and found I had broken a bunch of dampers. I think it was from a poor fit between the dampers and the ID type spring seats I had used.
