Question about break-in with big springs.
Okay, I am very close to starting my engine... it is a 396 with a solid flat-tappet cam, so I'm getting worried about break-in failure. I'm wondering if I should take the inner springs out before I start the engine up? Are the springs big enough to cause a problem?
Here are the spring pressures--- It is a Iskendarian solid camshaft, 240 duration, .530 lift. They are dual springs with an inner damper too.
8005-A TYPE: dual w/damper DIA.: 1.530"
RATE: 400 lbs per inch
INSTALLED HEIGHT: 1.875"
SEAT PRESSURE: 135 lbs
OPEN PRESSURE: 395 lbs
COIL BIND: 1.160"
Awesome, I will put 5 quarts in when the time comes. I've always used Valvoline, what viscosity would be recommended for So.Cal.?, and thanks again
