Some of you may remember a few years ago we fitted a Boport 1.5 roller cam to my car at Vince's the Saturday before Knott's. Bo didn't have the correct springs in stock at the time so I've been running the stock ones. Josh gave me a set of springs last week that were part of a big valve kit and i was wondering how they'd work with the 1.5. The specs are:
1.600 installed height110 lb seat pressure
0.805 ID
1.385 OD.
Any thoughts???

I have the same question for the installation of a FMS A237 roller cam. What does the installed height of the spring need to be and what is the necessary spring seat pressure open and closed? Many have told me that the A237 cam is designed to be run with stock springs. Is that true? Thanks!

Just to follow-up with this thread, I called Boport and he recommended his drop-in valve springs with increased pressure for use with the A237 cam. Based on that and my engine guy's advice, I'm gonna try them out. I'll let you know how it turns out.
