Seat pressure

Postby masracingtd1167 » Mon Oct 21, 2013 3:45 pm

I was thinking that I might be running too much valve spring pressure on my smallblock . It is an 18 degree head , titanium valves 850 lift on the intake 800 exaust Intake 280@.050 exaust 294@.050 114 center line It is 394 cubes . I cross with it at about 9200 rpm . Right now I have 410 lbs seat pressure and I wonder if it might free up some horsepower and save some broken lifters if I backed off on the spring pressure a little Thanks Bill
