I have an additional question. I will be having my 1966 Mustang 200 I6 rebuilt and the cylinders bored out, new intake manifold, carb, headers, etc to increase horsepower. I will be doing this through my local classic car mechanic. My question is: when a V8 is placed in a I6 car, the suspension, etc has to switched out to handle the V8. When a I6 is modified, will the 6 cylinder body need those same parts upgraded or will the suspension, etc be sufficient?
