    HP93 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from 35k and still going good I purchased this to upgrade my 2001 yukon 2500 in 2018. I did all recommendations by ATK. (Oil pump, headers, injector size, etc.) my only problem was one spark plug wasn’t tapped true. It was tight and proper torque was a guess, but after having everything set up and close to firing it off, I wasn’t going to yank it out for that only reason. After dyno tuning I had just under 300WHP. (4L80 an transfercase). I’ve since put 35,000 miles on the engine. Towing 7k loads distances of 1k several times. I’ve changed oil every 3k and have not had a single problem with this engine. I’m very impressed. Plus.. It’s always great to pull away from a rice burner in an old mans grocery getter off the light, but the 40 to 70 is where the power is at.

    Rated 5 out of 5 by from 6.0 lq4 I purchased this engine and it was delivered in 3 days. Engine was installed and tuned. It fired up immediately and it has ran flawlessly. I highly recommend this engine and I would purchase again.

    I have a 02 Silverado 2500HD with a 6.0L. I would like to know if I swapped this high performance 6.0L out for my stock engine would it pass a SMOG check?

    Asked by: DJBSR
    Hello DJBSR, unfortunately we do not build engines based on emissions nor do we test for it.

    I have a 01 Silverado 6.0.  Can I use the stock intake manifold and injectors and will the computer need to be retuned ?   And what is the warranty on it ? 

    Asked by: Matt90
    Yes, you should be able to use the stock intake as long as you have cathedral port heads. you can use your stock injectors, but will need to have the engine rr-tuned for this camshaft.

    Can you use a stock torque converter or does it have to have a certain stall?

    Asked by: Daily05
    You can use a stock torque converter with this engine.

    Does it matter if the core is a 5.3 or a 4.8 and not a 6.0 ,and what is the compression ratio on the motor,because I have a magna charger on mine now,or do you know if the magna charger will be ok on this engine?

    Asked by: Uncle Bumpy
    Hello, the core has to be a 6.0 or credit will not be reimbursed. Stock compression is 9.5:1 on this engine, but a power adder will void the warranty.

    What are the actual camshaft numbers? Lift, duration? How much lift will the valvesprings, pistons take? What is the current valve/piston clearance? What casting number heads do you use?

    Asked by: Railnut26
    The camshaft information and casting numbers are not available for this engine until after purchase as ATK will not release them.

    i figured about the stock intake manifold. my main concern was the oil pan/ timing chain cover, and my front accessories.

    Asked by: haeden
    You will need to swap all of those components over to this engine. What you see in the image is what you will get.
