finally got to the dyno today made 475hp and 534 ft-lb tq. here is the pull done with all the heavy stuff on like 22's and for some reason af ratios are off the charts did alot of tuning could not figure it out i think it is a prob. with the carb.

 

Good numbers man, thats a sweet truck.

 

what are your mods and engine?

 

it is a zz502 crate with 632 lift cam from 620hp/572 and roller rockers.

 

Nice. What type of exhaust and gears are you running? Tranny?

 

Now that's gotta be fun to drive!! Nice truck!

 

exhaust- is hooker lt. 3" to flowmaster 70 series. i am debating on going to magnaflow for the flow. gears- true trac 4.10s trans the bad part-stock nv3500. when it goes a th400 will go in.

 

very nice! You don't see that everyday.

that is a sweet ride. Man, I thought the days of looking under the hood and ONLY seeing a motor was over. Nice, very nice.
