Motion Replacement Engines

[vettebuilder]

Thanks for that info! So, did Motion stamp the pads on the engines or were they blank? I know bare replacement GM blocks were blank but short blocks had the CE and assembly date. Also, would Motion use a 512 block to build a 427 if the customer asked, or were they only used as 454? I see O much data on the internet about blocks and engines and stampings that I was curious as to who is correct and who isn't. I have no intentions of trying to duplicate any Motion car, I was just curious as to how the stamping and casting numbers went. I even read that Motion put their own stamps on some of the engines, so there is WAY more info out there than can possible be correct.
