VH/VK Crank Swap?

[hellbilly66]

i have searched and searched but cant find a solid answer. will the vk56 crank fit into a vh block? and vise versa? ive heard the crank snout is different (but that doesnt matter to me) and they share the same bore spacing. but has anyone dropped either crank into the other block?
if someone can post vh crank dimensions, i can measure and post vk56 sizes.

looking to destroke my vk56 and might have my crank up for sale.
(if anyone wants to stroke their vh)

vk56 crank measures:
mains. 2.515
rods. 2.125
main bearing spacing. 4.410

im probly a tad off on main spacing (112mm bore spacing equals 4.4094 but it was a quick measurement)

the counterweights have pretty tight clearences, but im sure the vh does too, (i havent been up close and personal with a vh)

any info would be greatly appreciated, and let me say that the wealth of knowledge on this site is by far better than any athoer nissan site i have ever came across.

thanks again for any input.

Crank spacing on the VH is 112mm too IIRC

I looked into this a while back. The bearings were pretty different in size and they're listed in both factory manuals.

i think i read on here that the mains were the same size? ill have to find out for sure tho.
i might just have to go get a vh crank and see how everything lines up.....also interested in finding out if the vh main girdle could fit.

thanks for the input so far.
