Hello, I just swapped out the gas guzzling/squirting/dripping holley 500cfm carb on my 87 fj60's 2F for a spanking new 350cfm list 7448 Holley. I'm just getting started with tuning the carb using plug reading, I searched for Holley tuning and came up with a starting point ( this board is the ) but does any one know the power valve size, jet sizes, and throttle cam color/ size that they've had the best luck with. Also, is the the .097 off-road needle and seat the correct spring loaded needle and seat for this application. Ohh and were roughly should the timing be for this combo? Thanks for the help.
