Crate Motors
I have a 380 360 crate and have had no problems with it. My friends has a 435 402 crate, in a Mirada and has no problems. It replaced a 300 360 with 3 years trouble free.
The only nice thing is everything is brand new and costs about the same as a rebuilt block with new pistons and nice roller cam. But like 340srule said you don't know how it was put together, and if you do it yourself you know how it was done.
