75 shot ok w/o pulling timing?
you would get away of it but if you've gone and tuned
it to the bone already, the gas might put you over the
top ping-wise. Stock late F-body tune leaves a lot of
timing on the table and is over-enriched at WOT. But
if you have any mods that raise timing and bias the
mixture lean (aftermarket MAF for example) you
would want to wade, not dive, into that pool. Jets are
cheap, step up 25HP at a time and look for trouble as
you go? If you get zero ping / KR at 50 then try 75, if
you hear anything funny then figure out what before
you crank it up.
