"My main 1600 that I have been posting about has a high rise cam (I was told that when I bought the car) and stainless headers. I have a few Datsun Zs and was wondering will any Z car 5 speeds bolt up to a 1600." Nope, different pattern. The U20 5- speed will, but it leaves you with a very tall 1st gear. Great for higher speeds, not so good in town. Toby
