LS3 mockup block

[Ken Sungela]

In search of a mock up LS3 block, or a junk real LS3 block and heads. I need this do do all the mockup work when building cars. I'm located in Rivervale, NJ . Please contact me if you have one.

All LS engines share external dimensions. You don't need it to be a LS3...it can just as easily be a 4.8...or 5.3...or whatever you can find.

OK, thanks. How about the exact position of the exhaust manifold bolt holes, all the same? Will a 4l
70e bolt up the same no matter what the LS engine?
