I agree. After the 318 high hp nonsense on YT its like why do people think doing it the hard way is effective? whats to prove? I mean build a 273 but dont expect much over 200 horse and be happy. Not being negative just why put all that stress on yourself...
Um , factory commando 273s had 235 hp with exhaust manifolds and a 500 cfm carb and they can easily make over 300 hp with some good bolt ons. Just think if you built one from the Pan up.
