Re: 143 Blueprint Cam Install
If you plan on running this car, get rid of those stock valve springs. They either (A) broke and dropped a valve, or (B) couldn't keep up with the cam allowing the valve to free fall shut at high rpm. This eventually pounded the keepers through the retainer allowing a dropped valve again. These are the main reasons that there aren't too many original L78s and L72 out there. We didn't seem to have any problem with the L88 springs in the old days.
