Hey bud would you mind sharing some specs I got a black 2003 serria 2500 hd crew cab and I use it for towing but i wanna start doing sled pulls whats done to the trans and motor would be very helpful for my build don't have to if you do not want.
start with bosch injectors, aftermarket turbo and downpipes aswell as a tune you’d be getting good power. this truck looks like it pushes north of 1,000hp so fully forget internals and built engine it’d cost ya 15k minimum
