Some people built racing motors before the Internet.
I dont know Murray, but based upon his age and the many magazine articles that I cant read (I dont have the magazines) I suspect that he did build a few motors. The 356 registry is not populated with all the 356 guys...many of them avoid forums for this exact reason. Many of the top 356 engine builders never visit these forums and its not because they are scared, its because they dont like all the drama. Its also a time suck they would rather avoid. I have met quite a few, and many of these guys do know what they are doing and have built some really cool motors and hotrod stuff. On the head venting question, I have a few that have always puzzled me and hopefully one of you guys may have a theory....we have discussed this before with no answer. So, Early Djet has head vents. Later Djet does not have head vents, but has air injection Ljet has no head vents. Does anyone have a theory why the factory kept flip flopping on this specific issue? I know racing was not on the line here, but was is longevity? Rich |

I know racing was not on the line here, but was is longevity? Remember that this was very early in the day of tighter emissions control and the advent of various types of FI systems. Some of these changes may have had to do with apparently unrelated issues (e.g. idle stability). Unless we've got a direct line to the engineers who made the changes, I suspect the exact reasons are lost. These cars were an amazing advancement in terms of emissions over the previous generation. Crankcase scavenging, evaporative fuel systems, tight mixture control over a wide engine speed and manifold vacuum range, etc. And to make it worse, they were all open-loop! I'm continuously amazed by where this has led us to today. Modern engine designs with engine management systems do an incredible job of managing all operating conditions while maintaining low emissions, good fuel economy, and drivability. |
