What was the horsepower rating of a 1978 Trans Am have?

Answer 1

This is a difficult question to answer, it depends on the year of the car, the model and the engine size. The vast majority of 78 TA's came with the 6.6L V-8 400cubic inch engine. This came with 180hp. I on the other hand have a 78 trans am, with the 6.6L, 400cubic inch, engine... big difference right? well there is acutally, mine has 220Hp, the biggest amount offered my GM in TA's at that time. One of the easiest but not full proof ways to see if your car is 180 or 220 is to see if you have air conditioning. The majority of 78's with air had 220hp, and most others came with 180 and no air. But like I said this is not fool-proof, you will have to check your vin number and engine number to see exactly. Easiest way I have found is to look at hitmans78 website, a quick Google search should come up with the link.
