Reply to "Engine overhaul"

I have owned two or three cars with a weight / power ratio, driver included, of 3kg / hp and I wanted at least as much with the Pantera, so I want around 450hp but without having to run too fast, hence the choice of a slight strocker which, according to George, saves 500 rpm.
I chose to keep the iron heads, even if they are a little more expensive and maybe work a little worse than modern aluminum heads, because I like the idea of the rustic american engine over 50 years old , all in cast iron, which still produces not far from  80hp per liter (80hp / 61 CI).
