My new truck cam from Crower came in the mail yesterday, pretty quick I think since they had to grind it. Just a reminder low lift, low RPM, high torque, and fuel economy designed to work with stock valve train and head.
Advertised Duration: intake.240 exhaust .248
Total lift: intake. .438" exhaust .450"
I've decided to to basically use the Sissle "Econoflow" head as descried on Page 90 of Leo's book for a model for my head.
"The head bolt boss in the middle of the intake ports should be shaped like a wing, but left in place. Removing the boss will gain about 5 CFM on a stock valve size head, but the subsequent loss of velocity in the port will more than offset the gain."
