stroker

If your truck is a daily driver then I personally wouldn't stroke the motor. I was going to do the same thing but after I researched it I realized I'd probably be replacing pistons twice a year the way that I drive mine. In case you didn't know the rods are already quit long in the motor. If you added longer rods you would be creating a lot of stress on the sides of the pistons. I decided to go with a built long block w/stage II cams insteads. Do a search if you want more info on it. It has been brought up more than once.

I ask this cuz I know that in some chevy engines you can use a crank from a diffrent motor to make a stroker?

Ive got a buddy that has one of the strokers. He said it wasn't worth the trouble and he has been dissatisfied (i think hw told me his was the second crank made). If you want to talk to him about it his screen name is "rusty". But as the saying goes "different strokes for different folks". Sometning else you might want to consider is the Sean Hyland Motorsports big bore block. I priced the both of them and at the time the bigbore route was cheaper and you didn't have the rod angle to deal with.

For a competitive drag racer like Johnny, this might make sense.
But for anyone else, why fool around with real displacement when effective displacement is a pulley change away? On a blown motor, it just makes more sense to bulletproof the engine and crank up the boost.
Witness the sick amounts of power produced by 1.5 liter F1 turbos or the 2 liter Toyota and Nissan GTP engines. Once they figured out how to keep the engines together, the sky was the limit -- some have estimated nearly 2,000 HP in qualifying trim.
p.s. -- they were running as much as 5 bars boost (73 PSIG)!

Speed 12: E-mail me if you want to get rid on the Manley rods and pistons.
Oh; a comment to dirtchicken: I'm pretty sure that longer rods actually decrease the side loading of the pistons, which is why (for example) on the 383 Chevy small blocks, a popular change is running the 6.0 long rod rather than the kinda short 5.7 the factory used with the 3.75 stroke crank in the 400 small block. The only problem in going to longer rods is avoiding the compression height problem where you get the pin up into the oil ring area. Other than that, as you might expect, longer is usually better!
