I dont think members are being negative or underestimating the 360- We are simply pointing out what prevents any engine by any manufacturer from making impressive power- pistons too far down at TDC! A 360 400 and 440 is soooo far from its potential and so not ideal with those smog era pistons. I understand if one has to run what they got though. If it were me Id have the engine add ons based around those low comp pistons- RV torque cam, stock 4bbl (Performer/Action Plus) intake headers turbo mufflers- ect.
