HP/Performance progression from 250 GTE to 365 2+2...

I think you can find the HP numbers here. Not the performance, though.

I think that finding reliable numbers is a little difficult.

The factory owner's manuals for the cars suggest 235 DIN horsepower for the 250 GTE, and 300 for the 330 engines. Those same sources are silent on acceleration figures for the 250. Oddly enough, the factory literature for the 330 claims a fairly wide range of 7.5 to 8.5 for a 0-60, and 25.5 to 27.5 seconds for 0-125.

On all of these 2+2, independent tests showed a variety of both 0-60 and quarter miles times. I think that the variation reflected both a variation between different examples of the same car, but also different launch techniques that were used.

One thing can be said, though: the cars definitely increased in power and (more important to perceived performance) torque throughout the years.

At some point I'd like to take my 330 to a dyno and find out how accurate the 300 DIN horsepower claim is.

I concour with the 250 Numbers - Mine was 0-64Kms in about 7.6 seconds and I have a couple of old docs saying about the same (old Italian Mag from 1963)... Of course I cannot verify the 125mph numbers - Since I did not take mine over 100mph - no seatbelts in my 61 - so I was a little scared to do much more than that

 

The 300 to 320 HP increase was the same as that going from a 330GTC to a 365GTC. A couple of old FML articles I have says the increase in torque was the more significant improvement, but they contain no figures.

It's been a long time since I drove a 330 GTC, but I do recall feeling much stroner acceleration in the 365. And the FML article indicates pretty healthy performance improvement of 0 to 100 times, from 16.7 down to 14.7.

 

for the 365, the manual says 320hp @6600, and it weighs 3223 lbs.
The old road tests I've seen say 0-60 in 7.1
