1999 trans am

Asked by Aug 28, 2017 at 10:08 PM about the 1999 Pontiac Firebird

Question type: Car Customization

Thinking about putting a 1980 350 v8 into my 1999
Trans Am. It currently has a v6. Just wondering if
would fit or what modifications would I need to do

The list to do this is very long and expensive! Check out the Pontiac-Oakland Club's website. They have a couple of threads about this. It can be done but it's not cheap or easy to do. HTH. -Jim


Sounds simple but it is not things like the strength of the transmission and running gear come into play with the added torque and power from a 350 vs your V6. Front suspension and brakes may also need changing depending on what your desired performance specs are.
