with out no cam or internal mods

plans so far LT's,pulley,cutout, custom tuned, e-fans, custom CAI,

it allready made 231/272 SAE 3 on the 20's with AF 11.0:1 factory tune with rear 02's off and TQ managment turned down 90%

 

ohhhhhh no PA of any kind

 

sure you can just put a turbo on it! thats not a cam or internal

 

it could be with all the right mods. I make 331 333 with cam. and full boltons.

 

but it falls under the Power Adder section

 

if you are going for just a dyno number.....

I would try every bolt on and an aggressive tune. I was told at one time that a 3.42 will actually show a better dyno number then a 4.10 or any lower gear cause it will let the dyno read better or something like that? Maybe someone more intelligent then me on that subject will chime in.

You also didnt mention anything about a motor? The 6.0 stock internals just bolt ons would be easier then the 4.8 or 5.3? lol just thought I woudl throw that out their.

 

Your not going to do it without a power adder of some sort.
Another mod would be the short accessory belt trick, but that won't get you there still.
The auto tranny absorbs a lot of the engine power.
Your just going to have to suck it up and place a power adder on there and go beyond that 300 HP mark.

it will surely be kinda hard to pass 300rwhp without any internal mods and by the time you spent all the money on bolt ons you could easily have reached cam or power adder costs

 

well someone told me yesterday i was crazy and couldnt be done.... i feel like it can be done if not very close....

of coarse its just a dyno number but in the long run it will help getting the yukon down the road as long as the TQ comes up with the HP

it currently has 3:73's in it ( factory gear)

 

well im glad everyone isnt like him......
