BTW,
Just for "You's guys" information, the last time I talked to Kent Wilcox, we discussed fabricating a test fiberglass air dam or front spoiler for the Tiger. He liked the idea. We hope to give it a whirl later on this fall. Want to wait until we can give it some time to look at the aesthetics as well as improved performance.
Regards,
Allan

<< Message: Re: Radiators (3.84 KB)>> Ray,
I am re-sending you my best sources of aluminum radiators that I sent you yesterday. I suggest they will be of more help on that.
I have asked Allan Connell to forward my own 4 row information, which includes Modine part numbers, and other tricks recommendations, cause I can't find my original in the 4000 sent mails.
As to spoilers, I haven't considered changing external looks. AS to blocking holes, good idea, and I have done that with the horns. These are little aids, not illness cure-alls. My straight bladed non-pancake motor fan (per Bob Palmeer's recommendation) is good for slow speed and heavy/stopped traffic. Won't do much at speed. The LAT hood is a good idea because of the rear NASA duct extractors, rather than the front scoop, unless you have carb clearance problems. Mine is arriving today, so I've no direct experience yet.
Watch your coolant concentration, no more than 2 years old antifreeze, distilled, not de-ionized water, overflow recovery system, calibrate temp gauge. Share information.
What more can I say?
Steve
