I thought the 6.0 stock put out more than that? Regardless I bet its so much more fun than the 4.8! Congrats

To the wheels? I doubt it would put out that much stock... Tranny upgrades could gain quite a bit.

[Chris]

Stock it puts 345 to the crank. I'm getting 325 to the tires

The only tranny upgrade done is a servo. He had up to 151 MPH on the dyno

Sounds great. Hope you got some video!

[kstruckcountry]

And I thought I needed to plan out my next tranny... lol

 

I'm hoping to start building one, but everything on this truck has been so reliable it may be longer than I think.

[Chris]

No I didn't. Not on the dyno. Got pics of it strapped down.

Sounds like the swap is going good... Congrats.

[Chris]

Except a few issues. My stereo doesn't shut off. I'm out of power steering fluid so I don't know if they didn't refill or I have a leak and there's a vibration. I think its the exhaust

How did you only lose 20 hp to the tires??

[Chris]

A tune. My intake. My exhaust. Figure a 15% loss I should be at 373 to the crank
