black91gt5.0 do you even know the motor in the Escort? Or are you just basing that off the fact it's a 4cyl? 55shot is easy to handle with the older CVH Escorts. I don't see why the Zetec would be any different. I wouldn't go over a 75 shot without alot of fine tuning and equipment though. 125 shot seems way too high though. Just my opinoin
