I use my '87 Grand Wagoneer to tow the pop-up. I got to thinking that maybe the timing could be set up a little better for towing. 360/tf727auto, performer intake, Qjet800, Jacobs ignition / coil, MSD Pro-billet dist. I also run 35" MTR's on an 8" lift. The Haynes manual calls for 19*BTDC and I can change out the springs in the MSD dizzy. Normally I have the timing aroung 12*btdc. Any suggestions on a timing setup that would help towing? economy is secondary to power. Thanks, Matt
