De-Stroke from 2UZFE to 1UZFE Crank

[Lextreme II]

1 & 3UZFE crank stroke is 3.25" and the stock 2UZFE stroke is 3.31" I wonder how would the 2uzfe block will rev with 1uzfe crank. Would shorter stroke increase rev and able to rev faster? What do u think of this combination?

From the cubic inch calculation its only about 5 cubic inches difference. Please see below. 281 CI is just like the 4.6 Mustang/Cobra. You can say its a de-stroke setup.

Sure, it's all about your rod ratio (and supprting valvetrain). The reduction in stroke would only be benificial to the max revs, while sacrificing very little in terms of displacement.

Would the above spec be ok as far as the rod ratio?

Bore: 3.710"
Stroke: 3.25"

1.77...and that's better than the 2jz, which is 1.65. There are other variables, but a great ratio like that can't hurt.
