I've recently bought a low mileage ZZ430 crate motor (s/n 28) and needless to say there was no paperwork with it. Does anyone have a copy of the factory paperwork that would have come with a ZZ430 engine?? I've bought GMPP Crate Motors before and there was always a packet of info with p/n's, dyno charts, instructions, etc..

Try this, it gives the basics ZZ385 remember this is a ZZ385 with a hot cam kit.

Paperwork for ZZ430
Hi I have the factory paperwork that came with my ZZ430 (S/N 063)
I could make you copies if you haven't already got the info you wanted.

ZZ430 Block casting #'s
The number off the block is 40243830 or possibly a C it is a little hard to read as the engine is still in the crate.
