confused about GAP
Ive read a ton of posts and searched a long time. Im confused about the gap. Oreilies says .054 and i read here alot of you setting it at .054. the hays manual that covers almost all fox bodys say .044. what should I set it at. I have a 89 GT with a MSD coil motorcraft platinum plugs and march underdrives trans-go stage 2 shift kit.
the car does well but I cant get it to peal out. and 2nd gear wont scratch. I think I need to change my rear end to a 373.
my real question is. what gap should I use .045 or .055

.054 on sefi models and if it won't peel and you got an aod 4:10's would be a good idea the aod has a 2.40 first gear ratio so to get it to do what a 5 speed 3.35 first gear ratio does you must put lower gears and often a stall convertor too

The one that provides you with better results. There is no specific rule etched in stone that says it has to be set to a specific clearance..... you need to evaluate based on performance tests. OEM spec is .048" - .052" or .052" - .056" depending on the calibration number. I would ditch the platinum plugs though...... the TFI ignition was not designed to work with them and they do not provide any gains for the expense. Just a thought.

advancing the timing deleviers spark earlier to start the cumbustion process earlier in an attempt to get all the burning done at proper time so it does not interfere with power producing stroke
