Sadly the reason I'm swapping is that the engine went bad.
I took it to a shop to have it tuned up, and the mechanic said the block was damaged.
The oil was filled with metal shavings.
I'm going to do an engine swap on my 79 Trans Am.
The original engine was a 403 and I'm going to be putting in a Pontiac 455 for a 74 Trans Am.
I want to know what I will need to change out to put the new engine in?
