Re: What is this fascination with DOHC?
Hi Tony, guys----------------I guess the only reason I can think of for a DOHC head would be the ease of working a hemispherical combustion chamber into the head design. This would be impractical and horribly expensive for a Z, but many, many years ago I owned a '58 MGA Twin Cam car that was set up this way. DOHC with a hemi combustion chamber, good for about 7500 rpm. That car was fast! There were only about 750 ever produced, for F Production racing against Porsches and Alfas. Close ratio 4-speed, about 70mph in second gear at redline. Great car for the "stoplight grand prix".
