Hello all. I have a few questions about swapping some parts between motors. I have a 6.2 vvt long block that I need all the external parts for, some hardware etc. I was planning to buy a newer 4.8 ( 58x ) motor on ebay, and taking everything but the manifold and swapping it to the 6.2. Is there any difference between fuel injectors and rails on the 2 motors? I can see injectors for the obvious reasons, but I wasn't sure on the rest. If anyone can tell me anything else that wont work, it would be greatly appreciated! This is going into a 53 chevy pick up so I was planning on using the harness, pedal, all the front accessories etc. from the 4.8 to put some life into the 6.2. 6.2 is losing the VVT and getting a cam so I already plan on doing a tune. Thanks

 

The intakes are different. The all 6.2 use rectangle port heads and the 4.8 uses cathedral port heads. Other than that all else should be the same.
