At redline, Does a Daytona have a rev limiter/governor?
Mine did not. Be careful, though, the official redline is 7500 rpm, but the tach is marked for 7700-7800 rpm.
In my experience I have never had the feeling I was going to over rev it like in other cars. It lets you know when you are getting there. The gears are long and fabulous.
It is a stretch to even call a Daytona's a Colombo engine. Owes more to the DOHC 290S, 315S, and 335S engines than the SOHC Colombo engines.

That one cost a head, piston, rod, all the valves, springs, 12 liners (rusted from the coolant). Although today I would just repair the head. But in 1998 I actually found a good set of heads and replaced them both after updating the valves and valve job.
375+- Affirmative, there is too much out there on Colombo vs Lampredi engines. Folks seem to think if the heads come off it is Colombo engine, and if the liners are attached to the head, it is a Lampredi engine. Colombo only worked for Ferrari for a short period of time and many Lampredi features were incorporated into the "Colombo" SOHC V12s fairly early in their lives and well after Colombo had left. Last engine that could realistically be called a Colombo engine is the 365 GT 2+2, 4.4 liter, SOHC V12. Even that is a stretch. Not in Wikipedia, though.
I had the throttle stick wide open on a 365 GTS (a 2-cam engine) during a test drive. When I pushed the clutch in to shift to the next gear, it pinned the tach needle, I'm sure that the engine revved to more than 9000 rpm. It scared the crap out of me, but caused no engine damage at all. These engines are very robust. I would bet that the missed down-shift mishap revved the engine even higher.
Even the best can't take too much. I had a very expensive (read $45k) SB2 race engine that the driver took to almost 12,000. Left an exhaust valve some where in the grass near turn 10A at Road Atlanta. The interesting part was the in car video. 5 speed, from 5 to 2 to 3. It was so quick that he had no idea. It just started running rough. The tach memory however told the tale. The owner didn't let me have the in car video.
Before the paddle shift and ratchet shifters in race cars, missed shifts could be catastrophic to the engine!
he Daytonas have relatively short chain compared to other 4 cams as cams are gear driven, not directly by tchain.
It was a great design and kept the chain to a reasonable length. It was the motor that should have been kept and that other disaster phased out.
C4/400/412 The cam drive and cylinder head, carb lay out was terrible. Rumor was it was an Agnelli family member designed it for an engineering school project and it needed to get built. With the C4 limited to 500 units it was OK but the decision was made to keep it and discontinue the Daytona design. Excuses were made why, hood height etc but were excuses. If the C4 400i motor will fit, so will the Daytona. Daytona is narrower and just as low.
