Short stroke turbo motor

[Got Torque Diffs]

Had anyone ever ran or heard of running
A 4.8 crank in a 6.0 block. Does anyone know
If the mains are the same diameter.
I've been in turbo 1st gen small block Chevy
Cars with short strokes and they are freakin rockets!!
But just curious if anyone has done that with a IV gen?

Same bearing diameters.

[George C]

Yes GM has done this already .....its called the ls327

But 4.8 crank has same bearing diameters

Would be a sick engine. What turbo would match up well to that?

[jansen]

I've always wondered but you can't ever find much info on this subject. I think you should be the guinea pig and try it!

[RS/SS 4.8]

I always thought that would neat. Ittl be different different from all the 6.0s and 408s on here.

[farmtruc]

same concept with a 427 4.0" stroke. somewhat short stroke with big bore.
they rev just fine!

[o2camaross]

So theoretically all you would have to do is drop a 4.8 crank and rods into a 6.0 and it'll be just fine? Does anyone make good 4.8 rods?

I bet a 76mm with a big turbine would be sick on that setup. And you can run L92 heads!
