So, as the title says I have a 1969 Caprice, it has a 350 that is all stock (other than the carb). I have seen a lot of things about swapping heads over, and I am already aware that Id have to get a different intake to go from the carb to the injected Vortec heads, but is this even possible to do on a 69' 350. I haven't seen anything dealing with a motor as old as this one, only 75 and newer. Plus if I did do this what would be the actual gains of the head swap? How much of a power increase should there be? This is my first project car and I have enough knowledge to get myself into trouble, but not enough to get back out of it, so any help is apricated.
