440 Engine tuning suggestions

DCR of 7.8 that what I aimed at once i had dug myself out a "BAD purchase" hole

This dictated by my Static CR, bore, stroke, rod ratio, allowed me to choose a cam that fulfilled my need to run on pump gas,on the street, with a motor that had what is considered a not street friendly 12:1 Static CR.

I found it a useful tool when trying to fit together a block and heads that had been seriously cut.
with a set of new pistons that now sat 40 thou proud of the deck.... i just cut the edge off them, to make a dome, now they miss the head.. :)
you may ask why.....and the answer is that it was all i had at the time...
i had purchased someone else's problem, mismatched chevy pistons in a slight overbore block with half a mile cut off the deck to make em work .. supposed to be a running "good" engine...
it came out good in the end.

mechanical curve is just a shorter version of the standard curve with vacuum advance hooked up to manifold vacuum

it would have been very easy to build an unworkable motor, that pinged at the slightest sniff of mechanical or vacuum advance, or one that needed race fuel

getting a handle on DCR saved my build.

its a useful tool, amongst many other useful tools
