420 hp 305?

somwone a while ago had a page with several 305 buildups on it. Yes I know its a 305, but it has to work until I get a 350-383

I saw this same buildup on someones Monte Carlo SS page. It made 400 plus horsepower but it was at i think 7200 rpm. Also,after running those ET's,the motor spun a rod bearing,probably from those high rpm's. Just something to think about for a street car.
