Some events let you pull in 2wd, i think you can have a hitch height of up to 32-36 inches

The sled pull thats happenening Saturday, Sept. 6th in Alvarado, TX is running NADM rules.

ok i guess i will fix my front hubs.


and i was woundering about my "stock" appearing turbo. i guess they dont have to know about the 17*hpop since its "factory". and a modded "factory" IDM, but im sure they will notice i have injectors and other bs.


so i guess i will run in the work stock class

hey im pulling in work stock too, might try out 2.6 class just to get my but handed to me too.

if its a sanctioned pull and dedicated sled trucks are going to be there.......have fun in the 5K rpm work stock class.......those boy's motors are built to spin insane rpms and by no means are those motors stock........just giving you a little warning.....

it cant be any worse than the abuse i put my truck through on a daily bases.

5000 rpms for a few seconds wouldn't hurt :humm:

so far so good, its my egt's i worry about.
