The new abridged format is great for cutting out the duplication problem that has plagued this site for so long, but it has left us with another problem. None of the posts are identified by whoever wrote them. Very difficult.
This morning, I'd like to know who wrote the following: " Taking a break from my Elites and Sevens, to examine some boxes of old Lotus records, including original USA dealer order sheets...", because I'd like to discuss these records with him. I am just about to take possesion of another Lotus 20, that was one of the two team Rosebud 20s. Lotus records show that the first 22 went to them, but they must have bought the 20s from one of the US dealers, Kyback or Chamberlain. Since Rosebud was in Texas, they'd be right in the middle. My new car was bought from Rosebud after it was crashed at the Sebring 1962 FJr support race and brought back to Ohio. Over the years, the rear part of the frame was modified to accept an Alfa motor, but the unique Rosebud rollbar remains. Please contact me off list at roger.siel...@telesistech.com . Hopefully your list covers racecars too. Roger

Valves - 2 new -------------- Hello Ian, The Mansell letter from Peter Yoeman ? had an awful lot of information. My thoughts are that when using an amalgamation of parts for any engine and not following a previously designed or specified engine ( all FWA or FWE or FWB) is that you must engineer your own. What rpm are you searching for, where do you want your torque to start (rpm), that will tell your cam supplier what to design and what compression he wants, what ratios in your gearbox and differential, and what flow figures would be necessary and then you look at your 1020 or 1500 (4000-13U) block and you look at your installed piston height and then determine what combustion chamber volume you will need to accomplish your desired compression and them you look at your valve and intake manifold and try to design enough flow to accomplish all of that and then look at your pump head or ? and weld-up or shave or buy a #5000 blank head to work your own magic on....it is so hard to buy off the shelf parts for a one off engine and have any hope that it will work. The neat thing about using an engine builder that has experience is that he will probably have made most of the mistakes you might make starting from scratch. I have blocks that are .450 different in height from crank center, pistons that are made for each block and heads that have been screwed around with by the best intentioned individuals and none of the parts are interchangeable. Valve and spring packages, guides retainers, buckets, and manifolds are all different.... developing an inventory of parts, a matrix of possibilities will not work unless you incorporate all variables and that is very difficult. - Wed, Apr 23 2008 8:43 pm 2 messages , 2 authors http://groups.google.com/group/Lotus-History/t/cc4ef4fb764793b9?hl=en

Dear Roger,
I am the administrator of this Group and was very surprised to learn
that it now has a new "abridged" format. I feel that Google might
have let me know!
When I looked at your message it was clearly stated at the top that it
was from you, and the same applies to the message from Mike Ostrov
that you queried.
It may be that we should all now subscibe to the "FEED" as they call
it. I have, and the layout seems fairly clear.
