The Isky 8005a is only 400lbs/in, so it would look like a new spring is in order, as I can the 150 seat pressure but only get to 390 open.

Question1, with the change in geometry my effective lift is down to .568, which if I calculate the ratio, I get an effective ratio of 1.56 (.568/.363), would that change your spring recommendation since it is not a true 1.7?

Question 2, if a spring change is in order, is there any advantage in looking at a beehive?

Thanks
