Im planning on buying a 1976 triumph tr7?
Offend them? The TR7 was junk from the start. Neat looking, especially as a convertible, but mechanically a joke. The best thing Triumph did to it was make it into a TR8, which was a TR7 with a Rover 3.5 V8. No one is going to care if you put a Ford V8 in this thing. In fact, I think it's an excellent idea. Think about it. The Sunbeam Alpine was a slick little British sports car with a 4 cylinder motor. The Sunbeam Tiger was an Alpine with a Ford 283. If not for Carrol Shelby, the AC would have been just another in a long line of British sports cars. The Ford V8 he wedged in it made it a legend, and possibly one of the most sought-after and copied cars on the planet. Remember, though, that once you have a Ford V8 in this car, you will have a dangerous machine that will break loose both when you accelerate and when you downshift, especially in the rain. This is how the one kid who died in my senior high school class was killed. Big motor, lightweight car, downshift in a curve in the rain, cut the car in half around a utility pole. The TR7 is very light, and has a very short wheelbase. With a big motor that has at least twice the power as the stock one, and weighs twice as much as well, when this car breaks loose you will not be able to control it. Don't say no one warned you.
