How do I identify a Chevy big block?
The first indication that a motor is a Big Block Chevy is if the codes are stamped above the timing chain cover. All Big Blocks are stamped there. Small Blocks are stamped on a pad in front of the passenger side cylinder head and are often covered by the alternator.
How do you tell the difference between a 427 and a 454?
The harmonic dampners are different (454 is larger diameter and externally balanced) and the 454 has a dowel pin in the back of the crank that locates the flexplate. The 454 SHOULD have a balance weight on the flexplate, but a 427 flexplate will bolt up.

How do I know if I have a 5.7 Vortec engine?
One easy way to identify the 5.7L Vortec engine is to examine the cylinder heads. The GM Industrial Vortec cylinder head was made by installing LT1 Corvette ports into an iron casting. The intake manifold bolts on with an 8-bolt pattern, unlike most other 5.7 GM heads that bolt on with a 12-bolt pattern.
