    I have the old 5.3 outta of my 2010 GMC Sierra and looking into turning it into a 383 Stroker. Has anyone done this or have any suggestions on what route I should take? Is it even possible? Any input is greatly appreciated

    It's possible. Google it, there are plenty of rotating kits/assemblies available for purchase. Do you have a good machinist? Do you have heads lined up?

    I can personally think of a few better ways to spend $3-5000+ but that's just me.

    To briefly touch on engine theory, the small bore LS based engine likes to spin, a stroker kit by design is essentially the opposite of that.

    I'm boring it 30 over and building it for 600 HP decided not to go with the stroker

    why not just go 6.0 with a maggy, that would put you close to your number.

    Because I pulled this 5.3 out my Sierra and I just have it laying around and decided to build it with my dad so he can have a "hot rod" once again.

    Iirc Tom Nelson said that doing stroker kits on oem blocks is not a good idea. The pistons begin to wobble at the bottom of the stroke.

    Hence why you see so many stoker motors, both na and boosted, live a very short life.

    OP

    Even 30 over, your 330.35ci LS based eng will not make 600 NA RWHP (on earth, assuming 14.7 atmospheric pressure) * Non- Unicorn internals

    Unless you are attached to that block for some reason most would argue that it's simply not worth the machining cost for such little performance gains. Unless that block is in bad shape and needs machine love anyway I would consider the typical LSX route to 800+ RWHP....... hone the da#n thing, toss stock stuff back in, leave the ring gap a little loose, and put the rest of your budget into turbo,fuel,trans,gears,etc...
