Yes its a 365 you can see the oil dipstick, the 512 has the sump tank on the other side next to the firewall Yes both the 365 and 512BB use 4 triple choke Weber carbs from the factory, whomever is selling one saying it has 6 twin chokes must be misinfomed as the twin chokes will not fit in the intake runners.
I think the 250 series (ALL engines) looked great. So does the posted P4. As far as the more modern cars go... I like what Ferrari did with the F430 and Enzo, and I like the 612 motor more than the 550/456 motors.
