Short Stroke LSX engine
 

Is there any short stroke factory crank for LS engines? I would like to build a modern version of a DZ302 based of a LS type engine. big bore short stroke.
As far as I have seen I think the difference between 4.8L, 5.3L, 5.7L and 6.0L
is basically same stroke different bore. So I assume aftermarkert crank is what I would have to do. Any input appreciated.

Basing your business plan on taking cubic inches away from an engine would equal bankruptcy. I will be suprised if anybody has a destroker kit.

6.0 block with a 4.8 crank. Shift at 9800. :D

Gearhead you a right on 9800 redline sounds good to me
except I thought the 4.8 had same stroke as 5.3 and 5.7
Does anyone have a stroke/bore list for all the different factory LS engines

4.8 = 3.27 vs 5.3 = 3.62 not sure if the bearing saddles are the same or not

for future reference it is DZ 302, not DC.:D

Since D and C are next to each other I am going to give him that one.... :thumbsup:

Thanks Clill
I should have known that. :hail:

I think GM did this a few years back, they put it into a ~2000ish Pewter colored 4th gen with TTII's.

Here is a quote I found:

Thanks Rybar,
I thought I had heard something like that engine once before.
With that much cam in it shouldn't it make a lot more horsepower then 435 at 6000RPM
even if at maybe 7000-7500RPM?
