1974 440

thanks IQ. Honestly I've been working on a job-related budget and that also allowed me to figure out how to graph in Excel.
I definately applaud the testing and I figured looking at the figures that it was something like that. We never see this kind of testing because the low budget builds don't have dyno time in the budget. There was a magazine test probably 20 years ago I tried to find and couldn't. It was an iron headed 440 that started with stacked head gaskets to get the compression to 8:1, and finished at 11:1 if i remember right. No changes other than removing head gasket thickness to increase the static. I want to say it used either the MP .528 or the .509 and the low compression results were similar to yours.
