My vote is for Tom's bad *** burban...My HD rolls a 360/452...do not know track times haven't ran the 1320 yet.

 

I think Tom's truck will out do his SUV when he's done with the upgrades. Keep in mind the Allison sucks more torque and HP.

I've dynoed mine at 384 HP and 512 Torque, RWHP is 304 and 409 Torque. Just Westers and Air intake.

 

i work at a dealership, and we have an 01 single cab 4x4 dually with the big block. we use it to transport cars between lots. the abusive driver(understatement) smoked the allison with 73k miles on it. lol

 

01 8.1L with Gibson shorties, air aid MIT, air hoe drop in, mannaflow custom, super chips off the self truck pulls really good no dyno or 1320's and none planned for the future. looking for a cam and tune package as i type any vendor interested in hooking my up.
