I compression tested my pinto a couple of weeks ago with the Crow Mild Street Cam (26874)
Cranking PSI was 180 on all four cylinders
I have to say the motor (and carb) has been built very well. Loads of torque, good idle and just feels very reliable I guess because all the power's down low and the engine doesn't need high revs to get off its arse
Woz your guess was bang-on. Power's gone by 5500-5800rpm
