Degreeing cams, new 1.659" Intakes

PostPost by: ggrenz » Sat Aug 29, 2009 4:00 am

Now fitted with new 1.659? intake valves (head work by John Edwards)- http://www.youtube.com/watch?v=5nyt_peHnQo and some clever suspension and brake work by Eric (AGE 19 and now an Elan/Alfa Fanatic!!) , it is now time to trade in your clunker/weak V10/M3/5 BMW, Viper, 800 HP Porshe, Lambo and similar ill begotten ilk/transmogrification for an Elan. You have until 8pm EDT yesterday.
Pay homage!, and bow low before the king of all the roads. http://www.youtube.com/watch?v=5OgDn0NYOcg

Somewhat closer to reality: Here is some data for my .375 lift cams with the new valves ('67Lotus 45/6378 Weber head)
