What gear did they dyno it in?

 

Minus the big wheels you would have 420 rwhp easy

 

IDK im guessing 2nd gear? could be wrong

 

yup weve told him to loose them but he likes them they came with the truck

 

Just saw its a rst very nice

 

thanks, we are going to put some 17s all around with drags out back and change his 3:23 gearing for a set of 3:73s so with his 3200 stall should be fun to drive

 

Naaaaaawzzzz

 

might have missed it but what is his setup ? and what size shot?

 

4.8L,cam, long tubes with a 3'' x-pipe 3'' duals, cai, pulleys,3200 stall, 3.23s, and a 100 shot todays last pull made 410rwhp and 391rwtq and still stock heads and intake he is planing on making 440rwhp by a few months without upping the juice
