Difference between 365bb and 512bb?

365 has the 6 exhausts, wet sump vs dry etc

 

No the 365BB's engine is only 4.4 ltrs (365cc x 12) while the 512BB's is 5 ltrs.

The easiest way to tell the difference is the 6 (365 BB) vs 4 (512 BB) exhaust pipes and the 6 vs 4 rear light sets. Also the 365 BB does not have air ducts in front of the rear wheels.

 

Nor the front spoiler....

also don't forget there were several versions of the 512BB

365 BB = 380 bhp
512 BB (carb) = 360 bhp
512 BB (Injection) = 340 bhp

the last ones (injection) had more torque - forget the actual numbers and the bhp values of the earlier cars were always suspect in those days...

 

Here are all of the differences I can think of:

365 has no front spoiler while 512 does
365 does not have NACA duct in front of rear wheels
365 has same width rear wheels as front; 512 has wider rears
365 has three tail lights/reflectors per side vs two per side in 512
365 has wire mesh rear grill material while 512 has horizontal slats
365 has three exhaust tips per side vs. two per side in 512
512 has three rows of ventilation louvers in rear deck vs. none or one for 365 (early 365s had none but later had one set in center)
Early 365s has one piece seats while later 365s and 512s have two piece seats with adjustable back rests.
365s have narrower rear track and bodywork.
365s have 4.4 liter flat-12 vs 4.9 liter for 512s
Power outputs:
365 = 360 DIN or 344 SAE net hp, 302 lb-ft. torque
512BB = 360 DIN hp, 333 lb-ft. torque
512BBi = 340 hp (DIN?), 333 lb-ft torque

365 compression ratio is 8.8 vs. 9.2 for 512s
365s have lower gearing (3.75 final drive vs. 3.21 for 512s)
365s have 34 mm carb chokes vs. 32 mm for 512 BB, BBi is fuel injected
365s tachometer red-lined at 7700 rpm vs 6800 (or 7000?) rpm for 512s
365 and 512BB speedo reads to 330 kph vs 512BBi at 320 kph
365s have window switches positioned in different position on console
512BBis have metric size wheels
365s and 512BBs have front grills extending completely accross with parking lights behind, 512BBis have truncated front grill with parking lights on each end.
512BBis have full size side mirrors on each side. 365s and 512BBs had none or small tear-drop ones.

I am sure that I have missed something.
