Very Possible he runs that time. What was the stock HP versus what he has now?U can do Very Little to "these" types of vehicles and get results. I have an 86 Grand Marqui 4 door monster.It ran good and with no tuning at all ran a 17.96.I did a Very good tune up. Added an MSD Coil.TPS adjustment, No EGR.Timing at 12,160 Thermostat.Polished Stock TB inside and thats about it. So, what did I really do? Not much, Went a 16.60. Then I went to an elec Fan and got rid of that clutch crap.Disconnected the Hot Water Lines to the TB.Added a Home Made Cold Air system but stayed with a Good Air Filter,NON K/N.A few more little odds and ends, BUT NO internal engine work. Now REMEMBER, this IS a 5.0 but NOT a Mustang Motor. IF that probe Gave me the hit and or I stole him out of the hole,who knows?,LOL. PS, I have a Race weight of 4,200, so thats next.btw- I have a 2.193 60'
