273 4-bbl Hi-PO Engine Appraisel?

I have to respectfully disagree with mrmopartech on his statement that the 273 Hi-Po "its not going to beat much." I ran my 273 for two years on the street and didn't run a 283 chevy or 289 ford that could beat it. It wasn't stock but it did run. I replaced it with a 68 340 motor in 80 nwhen I built it for show. I still have my "baby" today.
