Alright, it's time to plan my big block build. It's a stock 454 out of my 76 c20. My goals are to build it to make 400-500 hp. I'm not sure of right now of I am going to bore it over yet, as I don't no how the cylinder walls look. I would like to keep the stock bottom end if all possible. Could a good set of heads intake cam and carb accomplish 500 hp with stock bottom end? This is my first build, still have a lot to learn. What would you guys recommend as a good combo, and let's say I accomplished these numbers, will the good ole th400 hold up to that? I've heard they can hold up to 800 by some people but wounder if they were talking out there rear. I'm assuming I would at least have to get a new torque converter and trans cooler. I'm not really wanting to go over 5g on the motor but not sure if that will be enough lol . Looked at some superchargers, but those are pretty pricey, so I dicided to stay naturally aspirated. What have some of the you guys done with your bbc? Oh and it's going to be a weekend cruiser and something to haul something hear and there.
