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?

 

You wanna rev higher than 7200 ??? Because that's where you can take a forged 6.0 reliably with proper components.

 

that would be fun

 

yea i want to rev it higher then 7200 i shift at about 7000 now with the nitrous shutting off at 6800

 

Then build a destroked 5.7 (like a 302)

 

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

 

<--------------312ci, use a iron 5.3 block and bore it out, 4.8 crank, will be just as strong, slap some main/head studs and a main girdle and go to town

 

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

 

would it be hard to achieve around 450 rwhp with a 312 cube block?

 

valvetrain, not stroke will be the limiting factor. The 6.0 is basically a 350 stroked between stock and a 383.

 

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

 

Springs, pushrods, rocker arms, etc. The pieces that hold it together. You would have to dump a ton of money into a super valvetrain setup to make that work.

 

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)

 

everything that makes teh valves open and close. From cam, valve and everything inbetween.


Youd be a fool to destroke a 6.0 and stay with hydro rollers

 

it is going to be a soild roller cam, with matched up heads it is a track only car

 

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

 

stage274 is the guy that makes the girdle. send him a PM and see what he can do for you.

 

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.

 

Valvetrain girdle a plus

or the best lightweight parts money can buy. (hollow valves, 918's, Tit retainers, etc...)
