Ok. Which engine (silver or black) is best for creating a ZT?
And what were the differences between them?

I've heard the Silver is best for the mounts and possibly power. (takes higher)

And i've heard that the blacktop heads are better?

Why is this all so confusing?

 

Any ideas guys?

 

the black tops have a better sump design and the heads are better,i have seen both engines taken to the same power,
