the soft header problem isn't just in 95s, it is true for all the years...valve guides were 95... |

The 95's have the OBDIO-1 engine management unit, while the 96+ have the OBDIO-2 engine management unit. The 95's have a triffling richer mixture, and maybe a less restrictive intake, they also have the tripple input exhaust system. All told, maybe 5 HP, maybe 7 HP; but nothing to get all worded up about.
The early 95 cylinder heads were assembled with the same kind of valve guides as the last 348's. Near the middle of the 95 run, feedback from the 348 challenge cars indicated marginality in the wear characteristics of the valve guides, and they were changed from bronze to steel. But unless you intend to track the car, or use redline RPM levels more or less constantly, the whole problem has been overrated. Ferrari has also been very gracious in updating many customer engines under warentee. |

Some of the later 95s had the single intake tube which split later. A friend of mine has a sypder with a serial number of 104330 (approx) and while it is a 95, it has the 96 mods (different suspension, changes to the intake, changes to the injection system, etc. I think that the valve guide problem was in the earlier 95s, as was the ring problem. The exhaust manifolds also had a tendency to crack. All of these problems were allegedly fixed in the 96 mods. That's why there are two markets: 95s, and 96 throuh 99.

Giving it would be 10HP more, even if you are a good driver you would likely never realize the added 10HP on a 380HP car. You would probably see it on the track if you are capable of driving the car to its full capacity, which most of us don't (with some exceptions Matt, Jon, William etc.)and then you would likely see it only in lap times coming down fractions of seconds.

There's only one way to find out. Who wants to drag race? I need someone with a '95 355.

I have heard this also, to the tune of approx. 5-7hp or so more. |

The '95 has 2 separate air intake tunnels, rather than the 1 tunnel that splits into 2 after the hotfilm air mass sensor. Some mechanics believe that that results in more torque & HP due to the engine's ability to draw in more air. Not sure if it's true... |

$5,000 if you go independent and $ 10,000 if you have a little more to do and go F-service center!
As for the HP never heard that rumor. The 1995 had some problems with the valve adjustments and I believe some had cracked heads. If you have reasonable miles on the car I would not worry about that though, likely has been all sorted out! |

A dealer once told me that the '95 355 has the most HP than any other year the 355s were made. Is this true?
Also, what price range should the 30,000 mile service fall into? I've read anything from 5000-10000. |
