1/4 mile times

number is 8536.
I am in the mistd of learning the whole electronic ign thing like i said,
but for someone who had no experience with it up until now.. you can imagine how confusing inital,advance,curve,springs,weights,bushings,all this can be so im workin on it hah,
Also i just took the rest of the compression readings... and now thats the 1st compression test i have done but when its cranking the needle hit 150 everytime for a split second but never stayed up there, normally settled down at the highest from 135-145 and checked all but two cylinders because there kinda hard to get two so i tested the other 6.
Now since it did hit up to 150 but came back down is that 150 reading accurate or whatever the gauge settles back down to?
and that was throttle primary& secondaries open.. all that good stuff
