1.7 60' times are usually mid 12's. He may not get there unless he puts at least a 3500 stall and puts the car on a 200 lb diet. I would think low 1.9's would be respectable for his motor and car set up if he lost about 100 lbs and went up to approx. a 2500-2600 street converter. 1.9 60' would put him low 13's or perhaps a high 12.
