6.0? Im thinking about building a 6.0L Would i be able to put a smaller crank in it to do a D-stroked motor so i could rev it up higher and if so what size crank would i use?

I was thinking about using a 6.0 block because i want to shoot a big shot around a 400 on this motor, i think it would be safer then with the 5.7

what kind of rpms do you think that could be pulled too, and is the 5.3 block lighter then the 6.0L block, where do you find girdles ive really never seen them. Thanks

A company on ebay sells them, and it seems to be a reputable place (search it and go to their actual website, they have some pretty neat stuff). I haven't finished the car yet but I don't see why 8000rpms can't be achieved with proper valvetrain. Oh and not sure on if the block is lighter, I would assume so with the smaller crank and stuff

sorry to sound like a dunb *** but what is the valvetrain i work on my cars all the time but have never build a full motor yet

I'm shooting for 700rwhp @12psi
And yes, the valvetrain will be the big issue. Get good springs, pushrods, etc. I'd most likely go a solid lifter setup for something that high (I had solids in my Iroc, shifted at 7300 without fail, never hit 8 though but a bigger cam and I would be there)

Then you should be good, the shorter stroke will also soften the launch with less low end torque, but it'll make up for it on the top end. spray the **** out of it

6.0 block with 4.8 crank would make an excelent short stroke motor. it would wrap up quick.
as stated above, the valve train becomes a limiting factor at around 7500, not so much the bottom end.
