I have been away from the list for a while and am now finally in the = process of restoring my '68 400 convertible. I have a couple of questions: 1. 1968 header bars on the windshield were dull finish on the inside. I have just had mine replated by Tri-City and they did a great job. = However, they are now bright chrome all over. This may have been discussed before but I missed it and I need to know how is the best way to return the back side to a dull finish. Some have said that it is painted on but mine did not appear to be painted before I sent them to the platers. 2. I also need to know how the radiator is attached to the core support on the left or drivers side. There are two large holes that appear to have = had some form of grommet with bolts as compared to the right side that is attached to the two welded cage nuts. Any suggestions? Also, does anyone know where you can find the rubber grommets that contain the nuts for attaching the voltage regulator? Thanks to all in advance, Ed 68 400 conv.

(back) Subject: Re: Ram Air 101 From: <David_S_Smith@amat.com> Date: Mon, 2 Apr 2001 14:21:41 -0500 Rowan, Lots of the latest sport bikes use the "ram air" to force more air through = the carburator. From what I have read, the effect is minimal until the = motorcycle gets up well over 100mph. The way they prevent 'upsetting the carb' is by venting the carb to the = intake track so that the float boal sees the same pressure as the intake track. = If the float boal is not vented to the same pressure as the intake track, then = the fuel would be pressurized out of the float boal. They also jet the carb richer on the high end so that it can use the extra = air. Unfortunately, the engine runs rich at full throttle when at lower road = speeds. I remember reading about ram air in one of my issues of Roadracing World (motorcycle related), so maybe you can find something in their archives. http://venus.13x.com/roadracingworld/index.html Even if you don't find anything in the Roadracing World site, I would = still look through other motorcycle sites because the ram air is so common on modern = sport bikes. So, just how fast do you plan on taking that Hwy 17 pass? Dave

One thing to consider when = discussing compression is that a smaller motor will not have as many = problems as a large displacement engine with high compression.

(back) Subject: Water Pump Plates From: "Andy" <fbird68@ix.netcom.com> Date: Mon, 02 Apr 2001 23:25:26 -0700 I recall once reading somewhere (here?) that the holes in the plates behind a V8 water pump are supposed to be connected by small tubes and rubber grommets. My car has the plates but no tubes. Is anyone here familiar with this, and if I recall all of this stuff correctly, are the tubes, etc. still available? I've pretty much solved my cooling problems by putting in a high-flow thermostat and a four row radiator, but it still can reach 200 degrees sitting in traffic on a hot day. Thanks, Andy

I can't believe it is that easy to get the octane levels up, maybe it is. Does anyone else have opinions on the tolulene thing? Keith 68 H.O. Subject: Fuel additives From: "Dan Lawrence" <danl@fdn.com> Date: Sun, 01 Apr 2001 10:43:14 -0400 Several weeks ago I asked the group what to do about octane and what the 110 octane fuel was. After the aircraft fuel was explained it seemed to be a last resort for me because of all the trouble obtaining, transporting, etc. Curt left this link for a possible solution. http://www.wauknet.com/douthitt/pumpgas.htm I tried adding the 10% tolulene and couldn't believe the performance improvement. Actually, I had about 8% added in. I got a slight ping occasionally at full temp and when I should have down shifted. I got the gallon of tolulene from Ace Hardware for $8.50. This seems much easier to obtain and the results were fantastic. Thanks a million for the help. I would have never known about the info on the web.
