427 ID help?
Hi Folks-
I'm hoping the Vette community can help me out identifying the motor in my 70 chevelle. The previous owner says it's a 427 -- I have a casting number of 3963512 from the back of the engine. What other numbers do I need to ID this motor? The vin pad is clean except for a 7 -- block might have been decked. Thanks!

Look to see if there is a weight on the harmonic balancer or the flywheel.
The harmonic balancer weight will be on the inside of it (you will have to feel it).
If there is a weight it is a 454, if not a 427.
