I'm sorry guy's, for some reason I was thinking the 4.8 crank had more stroke, not less. That's not what I'm looking for.

Thanks.

 

No y'all got it wrong u should use the 6.0 block and crank with the longer 4.8 rods. You would have to either raise the deck height or get custom pistons but u wouldn't lose torque and you would get some of the advantage a shorter stroke provides with the longer rods having a motor that could eisily turn 8000 and make power all the way through the rpm rang with the right valve train/head combo

 

I love the concept of the large bore/short stroke, but if you want to rev it much over 7000 on a regular basis, the valve train mods are probably going to destroy your wallet.

 

I do not believe they can make a piston with that short of compression height. So you are suggesting he superdeck the block just for the marginal benefit of the longer rod?

 

Amen brother!

The real secret to building a high reving motor is in the valve train.

 

if you were going to turbo, the high rpm would have an advantage, but the valvetrain would be all spensive haha

 

If I had the funds for it Thats my dream engine a destroke 6.0 revving @8000rpms

Sorry, but I was unimpressed with that motor in the video, 540 hp at the flywheel is what? Maybe 450 at the wheels? My stock bottom end LS1 does that though a stalled auto trans.
