I recently bought a nice fixer upper. It's a 67 428, with a 4-speed manual trans that runs pretty well! My question is, what's the deal with the 428s? It seems like this was an engine that some dealers put in the car, but it is not one of the original 3 engines made for 67 firebirds? And more importantly, were all the 428s ram air intake? If so, am i robbing it of power by not having ram air?
thanks for anyone who can help. I am trying to learn as much as i can about my new hobby.
