That's pretty kickass for those mods, that's about a 14.2 in the 1/4 :biggthumpup:

Have you weighed the truck? Your 60' is pretty decent on street tires.

those times look pretty good as dave mentioned before it should be right around a 14.2 or 14.3. I just looked at a timeslip of mine and i ran a 9.13@77in the 1/8th and 14.24@96 in the 1/4.

No, not sure where I'd have it weighed.

I want to have the truck dyno'd and weighed out of curiosity. I have all power options/security. As far as mods I forgot to say I have a 180 thermostat and transgo shift kit, the trans was rebuilt with stock components except for kit and raybestos blue clutches/kolene steels.

Think I can hit the 13's in 1/4 or high 8's in 1/8 with a pcm flash? I'd like to have it dyno'd first to know where about shift points should be.

Man I'm happy as hell that all these hours of porting,etc paid off somewhere. The only real aftermarket hp adders were the fan and HS 1.7 rockers. :rockwoot:

I wieghed mine at a truck stop, most of them have certified scales.

I'd say it's possible to hit 13's with a flash. :biggthumpup:
