Disclaimer: Let's keep this thread on topic and relavent. I'm over the previous disagreement and I expect others to be as well. Mike made the best of the situation and turned a disputed subject into an excellent writeup (above). A lot of good technical information there, let's talk about it.
Tech Section:
A.) I am extremely iterested in the 35 hp delta in performance between ported and manifold vacuum. There are two reason this makes no sense to me, and I'm not sure what that means.
1.) Ported and Manifold vacuum should be equal at WOT.
2.) Vacuum advance should be inactive at WOT because there shouldn't be any measureable vacuum.
In either (both) case, their should be no measureable difference in ignition advance between the two and as such no measureable performance difference either, providing this was the only variable. Can anyone think of a reason for this ?
B.) I as well as I am sure several others are extremely interested in what total timing was. A timing light costs 40 bucks, if I have to buy one and ship it to Mraley I might do it - anyone want to pitch in?
C.) I find the discontinuity @ approaching peak HP interesting. Did whoever was driving the car do something odd like jump in and out of the throttle near peak HP?
D.) Stock motor w/ Stock Autolite (I am assuming this is a Pony rebuild?) made max power @ 5650 RPM?
E.) Nice torque non-curve
