I'm just wondering what the effects both good and bad would be of running 112 leaded fuel in a 4.6 motor with stock internals. much more power or blown engine or what? would spark advance need to be added?
without advancing the timing anything over 87 octane is a waste of money. if your going to run super or higher you have to advance the timing. I see no advantage to running 112 octane on a stock engine at all. just my 2 cents
