    Hello does anybody have cross section pictures for the DOHC Colombo V12 engine? I found one for the SOHC Colombo V12 engines and i was wondering if anybody had similar cross section view of the DOHC Colombo V12 engine like in the picture below in the attached file which is for the SOHC Colombo engine?

    Ferrari by Fitzgerald, Merritt & Thompson has similar cross-sections on the inside pages of the front and back covers, although I don't recall more specific detail.

    Not that I have such drawings but which DOHC are you thinking of? 290/315 or 275 4 cam?

    Jeff: The 290/315 engines are not Colombo designed. They are Bellantani designed. The 4Cam engine could be considered a Colombo by a pretty good stretch of the imagination, so he must mean the 1948-49 125 DOHC Formula One engines.

    IIRC, those shown are SOHC, noted as a 290 MM 1956 and a 275 GTB 1966.

    That is what I was leading to; was the OP to that level of what was and wasn't Columbo.

    Sorry for confusion, i meant mostly the 275 gtb/4 engines with dohc heads. I thought those had colombo block but with dohc heads?

    AlpenJäger1914 - I know that’s still a single cam motor, and you are looking for a twin cam, but it had been referenced above and I didn't want you spending time looking for the book (if you don't have it) only to find that it’s a single cam. I have not come across a sectional view of a twin cam.

    Page 27 of "World Supercars 1: Ferrari 365 GTB/4 Daytona" has a basic cross-section.

    Its a stretched 365 block obviously, but the basic architecture should be the same I would think.
