Getting the most out of a low comp 440

Schneider recommended 9:1 to get some pep out of it, which according to online CR calcs, shouldn't be hard to get by milling. I have measuring to do when I get the parts out of the bath.



Towing might be pulling a little pickup bed trailer to the dump or desert on flat ground. I don't tow more than a few hundred pounds with a shortbed half ton and only on flat 55mph country roads.

I don't intend to cruise around pinging the thing like an idiot. I don't have a problem stopping and backing off timing if things get out of hand, or backing up the compression with gaskets if it gets to be a consistent problem....or am I missing something? :-)
