Fine engines, main thing to know with regards to the 360 is that they were/are (unless someone before you has spent the money to change it) externally balanced ie you need a harmonic balancer and torque converter that are balanced for the engine, or as far as the torque converter you can buy a flexplate that has a big "bite" out of it (that is how they balance them) or if you want to use a four speed you'll have to have a balanced flywheel. Performance parts like headers, intake, carbs, ign. etc are interchangeble thru out the small block family. I have run my 73 with a 360 to a best of 15.3 @90 in the 1/4 and that was in drive (shifts at 4 grand, my cam makes power from 3 to 7 grand supposedly) on street tires thru full exhaust, if I manually shift, drop the exhaust and put a set of slicks on it I have no doubts 14.3's are there to be had. Only mods to the engine before installation were intake & carb, cam, headers and flex plate from B&M. You can use the magnum heads with only minor modding (which will bump CR a little) or else use of a crosswind intake or the like to make them usable on the 360 (due to the fact the manifold bolts go into the heads differently. Good engine in my opinion.
