[875.0curt]

hey i have a question i have aod transmission w/ shift kit, 2400 stall converter, and b&m ripper shifter, 5.0 stock block, gt40 heads port and polish, ford svo 1.6 roller rockers, cobra upper and lower intake with 1" phenolic spacer, 19 lbs injectors, 65mm throttle body, bbk cold air kit, and 73 mm mass air, and plished aluminum underdrive pullies, 3:73 gears, i run a 13.48 at 104 mph with street tires the car doesn't spin. if i leave on a dead stop, or if i am rolling like 2 km/hr, my car will not spin at ALL, why is that, and i bougha bbk fuel pressure regulator today, will that do anything for me, i am not sure if i am loosing power, my car runs a little to rich, just wondering on how to fix that.

Well if you are sure that it is running rich then put on the AFPR and also a gauge and then adjust it down a bit and drive it. You can have it dyno tuned to get the most of it. I would assume that with 3.73s there should be no problem spinning the tires. Heck even my bone stock 2.73 vert will roll em a few feet off the line and mine is a vert. By the way where do you have your timing set at. I hope at least 12 or 14 BTDC. Quite a few people even get to 16 or 18* BTDC.

the puter will try and keep the A/F trim stoich. a wideband or tune would be revealing as to richness.

good luck Curt.

my timing is set at 14, it was set at 18, but would bog down low...
