Ok, here we go. I purchased a 260z with the l26 motor that had a bad head, the lower end seems fine. I then purchased a 280z head that was rebuilt for replacement. Missing the head bolts, and finding them rather expensive, I found a l24 complete motor for $200, the owner says ran fine when he removed it, so he could install a v8. The l24 "looks" in great shape, but I haven't taken it apart. Now, with all these motor parts, what's the best combo? Or do I even know what I'm talking about? Thanks.

"Best combo" depends on what you want...

 

I guess I'm looking for the best performance with what I got.

So which heads and blocks do you have (the casting numbers) ?

I won't pick up the head until this weekend. But the guy said it was a high compression from a 280z. That's all I know about it this far. I have a l26 block, and a complete l24 motor, that still runs. This is my first Datsun car so I'm slowly learning.

These are pics of the motor that came with the 260z.

These are of the motor i bought for $200, which the owner said did run when it was in.

 

I don't have pics or numbers for the rebuilt head from the 280z which i will get this weekend.
