Cranking Pressure?
I just checked my cranking pressure with a compression gauge. And was shocked by the number (close to 300 pounds). The motor starts up fine without bucking. And seems to make good power, picked up 3+ mph over last years motor.
This years motor has 14.5 to 1 compression and 30 more degrees duration in the cam, than last years 12 to 1 motor. Should I be worried about the high number?

Re: Cranking Pressure?
I wonder if my hydraulic lifters are collapsing a bit decreasing cam lift and duration, when I test the motor. I almost can't believe the numbers. The motor starts to easy and runs well.
What does cranking pressure effect?

The gauge is a brand new gauge so I'm going to borrow one and see if it is the same.
