Stroke and bore numbers - ZR-1 Net Registry Forums

I remember reading in a post all the different bore and stroke combinations that have been used. I cant seem to find it though. Can someone point me in the right direction or list them for me?

I'd like to see how a stock stroke (3.660) X (4.125) bore engine will run.

And a couple more,
4.000 bore x 3.82 stroke = 385 cid
4.000 bore x 4.125 stroke = 415 cid
4.125 x 4.125 = 441 cid

Pete's next project...

A1990 · 10-23-2010

and....

4.10 bore X 3.75 stroke = 396

shaynezrl · 10-23-2010

4.125 x 4.125 = 441 cid that would be a really king of the hill. Just how much horse does these big cube lt5 produce?
