Yes.. but we aren't building a motor in 1971.... not one single person here would build a motor using all stock parts.. i'm not saying the outcome would be different just that all this talk about stock numbers and factory parts makes no sense..
I think there are two scenarios for this topic. One is this is a swap with what can be found as an ok motor that should run and the other is a full build before the swap.
In the case of dragging home whatever can be found, I think the stock comparisons from years ago are somewhat helpful, assuming time hasn't colored the memory too much. And I think any 360 (2bbl or 4bbl) versus a 383 2bbl only is the most helpful as most people aren't going to end up with an HP 383 when they find one. Not everyone, certainly there are those that get lucky, but chances are what is found is going to be a low compression 383 2bbl.
In the case of a build before the swap, it would be interesting to see how they stack up. My personal criteria would be stock stroke, zero deck pistons and a budget for cylinder heads that could buy 440Source Stealth heads or whatever SB head that cost the same or lower. Not sure there is a SB head that fits that budget, but if not then it is a knock against the 360. Maybe the trade off is the 383 can have either a roller cam or Stealth heads (but not both), while the 360 has a cheap option for a roller cam but is limited in cylinder head options.
BTW, in my opinion this discussion should be limited to stock stroke 360's and 383's. While a 408 or 496 are based on those, they aren't the same motor.
