Mildly modified 318 PCV valve selection

Ok
Minimum 950rpm is telling you something; don't blame the lethargy on the 12*. That cam is way too small to need or want 20 degrees, and the huge rpm drop and vacuum readings are screaming it .
Look,my 292/292/108 cam idled at 700 in a 360@14* idle timing. And I could retard it to 5*, drag it down to 550 with the clutch, and drive it in a parade for an hour. That 292 IIRC was [email protected]. And somehow your 214 wants 950 with 12*?
OK. have fun
