    79 Engine Swap

    I'm not sure. I found it off the Facebook marketplace. They sold the engine because they found a 455 HO and switched it for that.

    79 Engine Swap

    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.

    79 Engine Swap

    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?
